CPC Sample Questions Answers

CPT Code 62290: Discography, lumbar, single or multiple levels, radiological supervision and interpretation

This code accurately describes the procedure performed. The documentation indicates a lumbar discography was performed at a single level (L3-4) with radiological supervision (C-arm visualization).

ICD-10-CM Code M54.50: Low back pain, unspecified

This code is the most appropriate diagnosis based on the documentation. The preoperative diagnosis states " Low back pain possible spinal stenosis L3-4. " While spinal stenosis was considered, it was not confirmed. The postoperative diagnosis indicates no evidence of spinal stenosis or discogenic pathology. Therefore, the definitive diagnosis is low back pain.

Why other options are incorrect:

62292: This code is for a discography with injection of contrast and/or medication for therapeutic purposes. The documentation doesn ' t indicate any therapeutic injection was performed.

M48.061 and M48.07: These codes represent spinal stenosis, which was not confirmed in the postoperative diagnosis.

The operative service is anamputation of the left third toe at the metatarsophalangeal (MTP) joint. CPT28820describes toe amputationthrough the MTP joint, matching the “amputation at the metatarsophalangeal joint” language and the incision encircling the joint with removal of the toe after dividing tendons/ligaments. ModifierT2correctly identifies theleft foot, third digit. Diagnosis coding must capture the ischemic disease withgangreneplus thenon-pressure chronic ulceron the toe. In the answer set,I70.262represents lower-extremity atherosclerosis/PVDwith gangrene(left side per the option). The chronic ulcer is separately reported using the providedL97.528non-pressure ulcer code for the left foot/toe severity category offered by the choices. Antibiotic prophylaxis (Ancef), anesthesia type, tourniquet use/time, and technique details support the procedure but do not change the core CPT/ICD-10-CM selection. Therefore, the correct combination is28820-T2, I70.262, L97.528.

The provider documents history of COVID-19, not active COVID-19.

Z86.16 = Personal history of COVID-19

J18.9 = Pneumonia, unspecified organism

Codes U07.1 and U09.9 are for current or post-COVID conditions, which are not documented here. Therefore, A is correct.

For this scenario, two surgeons are working together, each as a primary surgeon. Therefore, the correct coding requires the use of the modifier -62, which indicates co-surgeons.

The transthoracic approach to excise the damaged portion of the vertebral body is coded with 63087.

The insertion of the bone graft and metal plate is coded with 63088.

Both codes are appended with modifier -62 to indicate that two surgeons worked together as primary surgeons on this case.

The Schede thoracoplasty for empyema is accurately described by CPT code 32905, which covers the radical procedure involving the resection of multiple ribs and often the obliteration of the pleural cavity to treat chronic empyema.

Penile prosthesis coding is determined by thetype of deviceand whether the procedure is asimple insertion, areplacement, or a more complex scenario. Anon-inflatable(malleable or semi-rigid) penile prosthesis is specifically reported withCPT 54416. Inflatable devices are coded differently (commonly with a different code family), and replacement/revision services may also have distinct codes depending on what is removed and replaced. In this question, the vignette is straightforward: erectile dysfunction treated with insertion of anon-inflatable prosthesis—no mention of prior implant, revision, or removal—so the correct code is the primary insertion code for that device type. The distractors include other penile procedures and prosthesis-related codes that do not match “non-inflatable insertion.” CPC exam tip: lock onto “non-inflatable” vs “inflatable,” and then confirm the action isinsertionrather than revision or replacement. That leads to54416.

K0001 = Standard wheelchair

Other K000 codes represent specialized wheelchairs

1. Procedure and CPT® Code Selection:

The patient received IV hydration therapy with normal saline, which lasted for 1 hour and 30 minutes.

CPT® Code 96360 is used for initial IV hydration for the first hour. This code applies to the first 31-60 minutes of hydration therapy.

CPT® Code 96361 is used for each additional hour of IV hydration. Since the hydration lasted 1 hour and 30 minutes, 96361 should be reported once to cover the additional 30 minutes after the initial hour.

2. Rationale for Excluding Other Options:

Code 96365 is for initial IV infusion for therapeutic, prophylactic, or diagnostic purposes, rather than hydration, and is not applicable in this case.

Code 96366 is used for additional therapeutic, prophylactic, or diagnostic infusions and does not apply to hydration services.

Option A (96360) would only cover the initial hour of hydration, missing the additional 30 minutes, which is appropriately coded with 96361.

3. AAPC and CPT® Coding Guidelines:

According to AAPC and CPT® guidelines, 96360 should be used for the first hour of IV hydration, and 96361 should be used for each additional hour or portion of an hour beyond the initial 60 minutes.

Therefore, the correct answer is D. 96360, 96361.

In ICD-10-CM coding, personal history codes are used to indicate a patient’s past medical conditions that no longer exist and are not receiving active treatment, but that may influence current care or require continued monitoring.

A. is correct because a personal history code can indeed be reported as a primary code if the encounter is specifically for screening due to a past condition.

B. is correct because personal history codes can be reported with follow-up codes to indicate that the patient is being monitored for recurrence of the past condition.

D. is correct because a personal history code is used when the patient no longer has or is being treated for that condition, but it remains relevant to the patient’s health history.

C. is false because a personal history code is not used indiscriminately on any medical record; it is only appropriate when the past condition is relevant to the current encounter or impacts current patient care.

Therefore, the correct answer is C. A personal history code is acceptable on any medical record regardless of the reason of the visit.

Medicare Part B provides coverage for outpatient services, including physician services, preventive care, outpatient procedures, diagnostic tests, and durable medical equipment. Part B is a key component of Medicare, covering medically necessary services and some preventive services.

A. Part C (Medicare Advantage) includes all benefits and services covered under Parts A and B and often additional services, but it is provided through private insurance companies.

C. Part A covers inpatient hospital care, skilled nursing facility care, hospice, and some home health services.

D. Part D provides coverage for prescription drugs.

Therefore, the correct answer is B. Part B.

Procedure: Hepatitis B vaccine administration for a Medicare patient on dialysis.

CPT® and HCPCS Codes:

G0010: Administration of Hepatitis B vaccine.

90740: Hepatitis B vaccine, dialysis or immunosuppressed patient dosage, 3-dose schedule.

ICD-10-CM Codes:

Z23: Encounter for immunization.

N18.6: End-stage renal disease.

Z99.2: Dependence on renal dialysis.

Code Selection Justification: G0010 is used for the administration of the vaccine for Medicare patients, and 90740 captures the specific vaccine for dialysis patients. The ICD-10 codes represent the encounter for vaccination and the patient ' s dialysis status.

Dr. Burns is providing initial hospital or birthing center care for the evaluation and management of a normal newborn infant. CPT code 99460 is used to report initial hospital or birthing center care, per day, for evaluation and management of a normal newborn infant. This includes a comprehensive history, examination, and medical decision-making. The description of the service provided fits this CPT code accurately. References: CPT® Professional Edition (current year), AMA.

Omalizumab is a drug reported withHCPCS J2357, and the dose is converted into billable units based on the code’s unit definition. In CPC-style questions,150 mgis commonly represented asJ2357 × 30 units(i.e., 5 mg per unit → 150/5 = 30). Administration is atherapeutic subcutaneous injection, reported with96372(therapeutic, prophylactic, or diagnostic injection; subcutaneous or intramuscular). Vaccine administration codes (90460/90471) are not appropriate because omalizumab is not a vaccine. For diagnosis, the statement includesstatus asthmaticusbut does not specify severity category (mild/moderate/severe persistent). In the options provided,J45.902is the “unspecified asthma with status asthmaticus” concept, whereas J45.52 requires severe persistent asthma with status asthmaticus (not documented). Therefore, the correct pairing is96372 + J2357 × 30 + J45.902. CPC exam tip: match administration code type (therapeutic injection vs immunization) and choose the most specific ICD-10-CM supported by documentation.

Complex (arm, 4 cm) → 13121

Intermediate legs total = 20.5 cm → 12036

Simple face closures coded separately:

12013 (cheek)

12011 (nose)

Modifiers allow separate anatomical reporting.

Correct answer: A

CPT biopsy codes for the skin are selected bytechniqueand whether the biopsy istangential (shave), punch, or incisional. In this scenario, three different biopsy techniques are performed onthree separate lesions: anincisional biopsyof a deep lesion (upper arm), apunch biopsy(forearm), and ashave biopsy(shoulder). The correct primary codes are11106(incisional biopsy, single lesion),11104(punch biopsy, single lesion), and11102(tangential/shave biopsy, single lesion). Because each is a distinct lesion and a distinct technique, CPT coding uses the appropriatebase codesfor each technique rather than “add-on additional lesion” codes, and you do not automatically apply modifier-51in CPT-answer logic unless the question specifically tests payer/claim-processing conventions. The CPC exam typically expects the straightforward reporting of all three correct biopsy codes when performed on separate lesions with separate specimens submitted. Therefore, optionBis the best match.

This is a subsequent nursing facility care visit.

MDM Analysis (2021+ E/M Guidelines):

Problems: Multiple chronic conditions → Moderate

Data: 4 labs + telemetry → Moderate

Risk: Prescription drug management → Moderate

99309 – Subsequent nursing facility care, moderate MDM

Why others are incorrect:

99307 / 99308 – Low complexity

99305 – Initial nursing facility care

For a patient in observation care, selecting the correct E/M codes requires evaluating each day ' s service level and the provider ' s documentation.

Day 1: The patient was admitted for observation, and the physician prescribed IV and SQ insulin, noting diabetes with hyperglycemia requiring complex management. The CPT® code 99235 is appropriate here because it represents an initial observation or inpatient care for patients with high-complexity medical decision-making (MDM), which aligns with the patient ' s unstable glucose and the management requirements.

Day 2: The patient ' s glucose levels improved, and the provider documented spending 25 minutes with the patient in continued observation care. Since this is an established patient with continued observation, 99231 applies here, indicating subsequent observation care with low MDM complexity.

Day 3: The provider documented spending 15 minutes with the patient, whose glucose levels normalized, and then discharged the patient from observation care. Code 99238 is used for a discharge from observation care and is selected based on discharge times under 30 minutes.

These codes were selected based on CPT® guidelines for observation care and the provider’s time-based documentation. This matches the medical decision complexity documented per the case and code descriptions available for observation care management.

1. Procedure and CPT® Code Selection:

The urinalysis performed was non-automated and without microscopy.

CPT® Code 81002 is appropriate for a non-automated urinalysis without microscopy. This code accurately reflects the test performed in the office.

2. Diagnosis and ICD-10-CM Code Selection:

ICD-10-CM Code R30.0 is used for dysuria, which was one of the patient ' s presenting symptoms.

ICD-10-CM Code R10.30 is used for lower abdominal pain, another presenting symptom.

Since the urinalysis ruled out a urinary tract infection, N39.0 (UTI) is not appropriate as a final diagnosis.

3. Rationale for Excluding Other Options:

Code 81000 (in options A and B) is for a urinalysis with microscopy, which was not performed here.

N39.0 is used when a UTI is confirmed, which is incorrect for this case since the urinalysis was negative, ruling out UTI.

4. AAPC and CPT® Coding Guidelines:

AAPC guidelines recommend coding based on the symptoms when a specific diagnosis (such as UTI) is ruled out. Therefore, R30.0 and R10.30 are appropriate symptom codes for this encounter.

Thus, the correct answer is C. 81002, R30.0, R10.30.

This scenario involves anon-pressure chronic ulcerwithgangrene. For non-pressure chronic ulcers of thethigh, ICD-10-CM usesL97.1-codes. “Fat layer exposed” indicatesseverity with fat layer exposed, which corresponds to the specific 6th character level (not just skin breakdown). The correct thigh code here isL97.112(non-pressure chronic ulcer of right thigh with fat layer exposed). Because the ulcer is described asgangrenous, ICD-10-CM instructs tocode additional gangreneusingI96when gangrene is present with an L97 non-pressure ulcer. Sequencing places the ulcer code first (it fully describes site and depth), then the gangrene codeI96as additional. ThereforeI96 + L97.112are both required, and the correct option presented isI96, L97.112(Option C). Mnemonic:L97 = Location/Layer,I96 = Ischemic gangrene add-on.

00813 = Anesthesia for colonoscopy

QK = Medical direction of 2–4 cases

99100 = Extreme age

99140 = Emergency anesthesia

The emergent endovascular repair of an infrarenal abdominal aortic aneurysm with an aorto-aortic tube endograft is coded with CPT 34702. This code includes the deployment of the endograft and the necessary balloon angioplasty for sealing the proximal and distal attachment zones.

This operative report documents anew permanent dual-chamber pacemaker implantation: creation of a subcutaneouspocket, placement oftwo transvenous leads(oneatrialand oneventricular) via a peel-away sheath, confirmation of thresholds, and connection/insertion of thepulse generatorinto the pocket with layered closure. CPT pacemaker insertion coding is determined by thenumber of chambers/leads placedduring the session.33208is the correct code for insertion of adual-chamberpermanent pacemaker system (atrial and ventricular leads with generator).33206is for asingle-chamber ventricularsystem and33207is for asingle-chamber atrialsystem, so neither matches a dual-lead implantation. Reporting 33206 and 33207 together is not correct because CPT provides the single comprehensive dual-chamber code when both leads are placed. The fluoroscopic guidance and catheterization lab setting support how the leads were placed but do not change the CPT selection, and “challenging due to agitation” does not by itself create a separate reportable service. Therefore, report33208.

The prefix “sub-” means below or under.

Common examples include subcutaneous (below the skin) and sublingual (under the tongue).

This is a core concept tested under medical terminology on the CPC exam.

1. Procedure and CPT® Code Selection:

The physician administered the MMRV (measles, mumps, rubella, and varicella) vaccine subcutaneously and dose 3 of Hepatitis B vaccine intramuscularly. The physician also provided counseling on routine immunizations.

CPT® Code 90460 is used for immunization administration with counseling by the physician for patients 18 years or younger for the first or only component of each vaccine.

CPT® Code 90461 is used for each additional component in a vaccine with counseling.

90710 is the code for the MMRV vaccine.

90744 is the code for the Hepatitis B vaccine (pediatric).

2. Application of 90460 and 90461:

For the MMRV vaccine (which has four components: measles, mumps, rubella, and varicella), 90460 is reported once for the first component, and 90461 is reported three times (once for each additional component).

For the Hepatitis B vaccine, 90460 is reported again since it is a separate vaccine with one component.

3. Rationale for Excluding Other Options:

Option A (90471, 90472 x 4, 90707, 90746) uses codes for vaccine administration without counseling and incorrect vaccine codes (90707 for MMR instead of MMRV and 90746 for adult Hepatitis B instead of pediatric).

Option B and Option D also contain incorrect vaccine codes and do not correctly apply the counseling administration codes.

4. AAPC and CPT® Coding Guidelines:

According to AAPC guidelines, 90460 and 90461 are the appropriate administration codes for vaccines with counseling provided to pediatric patients, with each component of a multi-component vaccine coded separately.

Therefore, the correct answer is C. 90460 x 2, 90461 x 3, 90710, 90744.

1. Procedure and CPT® Code Selection:

The scenario describes a labial gland biopsy of the salivary gland, performed in the office with a local anesthetic. The provider made an incision in the lower labial mucosa and took tissue samples from the salivary gland for biopsy.

Code 42400 is the correct CPT® code for a biopsy of a salivary gland. This code is specific to a biopsy without a more extensive excision or major surgery, aligning perfectly with the scenario of sampling salivary gland tissue.

2. Ruling Out Other Options:

Code 42408 is for the excision of a deep lobe of a parotid gland, which is a more extensive procedure than a simple biopsy and does not apply to this case.

Code 42405 is for the removal of an entire submandibular gland, which is a full excision and not applicable here.

Code 42450 is used for the removal of a sublingual gland, not for a biopsy of the labial salivary gland.

3. AAPC and CPT® Coding Guidelines:

AAPC and CPT® guidelines direct coders to use 42400 for minor biopsies of salivary gland tissue, particularly when only tissue samples are taken for diagnostic purposes, as described in this case.

Based on CPT® coding guidelines, the correct answer is C. 42400.

The physician performed anorthopedic manipulation of the elbow under anesthesia, which is reported withCPT 24300(manipulation, elbow, under anesthesia). The anesthesia service is separately reported by theanesthesia provider(the anesthesiologist/CRNA) using an anesthesia CPT code, but the question asks specifically what is reportedfor the physicianperforming the manipulation—not the anesthesiologist. Therefore, you donotassign the anesthesia code (e.g., 01710) to the manipulating physician. Option A is incorrect because it includes anesthesia coding under the physician. Options B and D include24605, which represents a different service (not the correct manipulation-under-anesthesia code for this vignette). CPC exam strategy: identifywhois billing (surgeon vs anesthesiologist) and select the CPT code that describes the physician’s operative service. Here, the physician’s work is the manipulation itself, accurately captured by24300alone.

This is destruction of malignant lesions (SCC).

17261 = Malignant lesion destruction, trunk/arms/legs, 0.6–1.0 cm

17262 = Same location, 1.1–2.0 cm

Feet are included in trunk/arms/legs.

Therefore, 17262, 17261 is correct.

Debridement coding depends ondeepest tissue removedand thetotal surface areadebrided at each depth. Debridement “tomuscle and/or fascia” is coded with11043for thefirst 20 sq cm (or part thereof)at that depth. The lower-back wound involvesfascia, so report11043(no add-on 11046 is needed because the described size is below an additional 20 sq cm threshold). The shoulder (8) and lower-leg (16) wounds involvesubcutaneous tissue, which is coded with11042for thefirst 20 sq cm (or part thereof)at the subcutaneous depth. Their combined area is24 sq cm, so you report11042plus add-on11045for theadditional 4 sq cmbeyond the first 20. Because two different depth families are billed (fascia vs subcutaneous), adistinct procedural servicemodifier (here-59on 11042) supports reporting both depths when documentation shows separate wounds/levels treated. This matches optionD.

Medicare provides specific codes for screening colonoscopy based on the patient ' s risk factors. For a Medicare patient scheduled for a screening colonoscopy who is at high risk (such as those with a history of intestinal polyps), the appropriate code is G0105.

G0105 is used for colorectal cancer screening; colonoscopy on individuals at high risk.

HCPCS Level II, current year

Medicare Guidelines for Colorectal Cancer Screening

72080 – Radiologic examination, spine; thoracolumbar junction, 2 views

Correct anatomy and number of views

Why Other Options Are Incorrect:

72020 – Single view only

72114 / 72084 – Standing or scoliosis series

In this scenario, the procedure involved the excision of a large sacral pressure ulcer with deep tissue damage that required muscle and bone removal and was followed by a layered flap closure. The coding reflects both the extent of the ulcer and the procedure performed:

1. CPT® Code 15937: This code describes excision of a pressure ulcer with muscle and bone removal followed by flap closure, which matches the detailed procedure performed on the sacral ulcer.

2. ICD-10-CM Code L89.156: This code is used for a stage 4 sacral pressure ulcer, indicating the presence of deep tissue damage down to muscle and possibly bone, which aligns with the clinical findings.

Explanation of other options:

A. 15933, L89.153 and B. 15931, L89.153: These codes do not adequately describe the excision with muscle and bone removal nor the stage 4 severity of the ulcer.

C. 15935, L89.156: Although L89.156 is correct for a stage 4 ulcer, 15935 does not account for both muscle and bone excision with flap closure.

Therefore, the correct answer is D. 15937, L89.156, accurately capturing the procedure performed and the severity of the ulcer.

Shave removal → CPT 11300–11313, not excision (11400–11646).

Face (nose) → 11310–11313

0.6–1.0 cm → 11311

Inflamed seborrheic keratosis → L82.0

11765 = Excision of nail fold (wedge excision), ingrown toenail

TA = Left great toe

Other codes are incorrect:

11730 = Partial nail avulsion

11750 = Nail excision

11755 = Biopsy

Correct answer: 11765-TA

The epididymis is a structure attached to the testes that stores and transports sperm.

It is part of the male reproductive system, not the urinary system.

This concept falls under anatomy and physiology, a core CPC exam domain.

99222: This code is used for initial hospital care, per day, for the evaluation and management of a patient, which requires a detailed or comprehensive history, a detailed or comprehensive examination, and medical decision making of moderate complexity.

The documentation shows a detailed history (including HPI, ROS, PMH, SH, and FH) and a detailed examination (covering multiple organ systems). The medical decision making involves the management of an acute asthma exacerbation, which includes admitting the patient to observation status, administering oral steroids, and planning for further diagnostic testing.

1. Procedure and CPT® Code Selection:

The scenario describes the repair of a bleeding vessel in the patient’s right hand. The procedure involved clamping, cleaning, preparing the wound, suturing the vessel, and confirming blood flow post-repair using a Doppler probe.

Code 35207 is the correct CPT® code for a repair of a blood vessel in the hand or finger. This code specifically covers the repair of an injured vessel in the extremities, which includes the hand.

Code 35206 is for vessel repair in the upper arm or elbow, which does not apply to this case, as the injury is located in the hand.

Code 35702 is for exploration of a vessel but does not cover vessel repair, making it unsuitable for this procedure.

Code 35236 pertains to the repair of vessels in the lower extremities and is not relevant here.

2. Modifier:

Modifier RT is used to indicate that the procedure was performed on the right side of the body.

3. AAPC and CPT® Coding Guidelines:

AAPC guidelines specify the use of codes in the 35201–35286 series for direct repair of blood vessels in specific anatomical areas. For hand vessel repair, 35207 is the precise and recommended code according to CPT® guidelines.

Thus, based on the CPT® guidelines and procedural details, the verified answer is A. 35207-RT.

Procedure Code:

90945 – Continuous renal replacement therapy (CRRT), daily

Includes repeated low-level E/M monitoring

Correct for CVVH

Diagnosis Codes:

I10 – Essential hypertension

N18.9 – Chronic kidney disease, unspecified

Why others are incorrect:

90935 / 90937 – Intermittent hemodialysis

90947 – Pediatric CRRT

ICD-9 codes (112.9, 110) are invalid

The CPT code 10005 is for fine needle aspiration biopsy, including ultrasound guidance, for the first lesion. CPT code 10006 is for each additional lesion with ultrasound guidance. Since the provider aspirated tissue from three nodules, the coding should be 10005 for the first nodule and 10006 x 2 for the additional two nodules.

AMA ' s CPT® Professional Edition (current year)

“Three-view imaging of both hips and the pelvis” corresponds toCPT 73523(bilateral hips with pelvis, 3–4 views). Because the same study is repeated laterthe same daydue to a new event (fall from bed) and is interpreted by thesame radiologist, the correct repeat modifier concept is-76(repeat procedure by thesamephysician/qualified health professional). The most accurate reporting is73523for the first study and73523-76for the repeat study. Among the provided options,Dis the only choice that includes both73523and the correct repeat-by-same modifier-76. The inclusion of-51in option D reflects a multiple-procedure concept that is not the primary modifier logic for a true repeat of the same radiologic service; however, the CPC exam intent here is to recognize73523and that the repeat isby the same radiologist, requiring-76(not -77). Key learning point: select the correctstudy code by views, then apply-76for same-provider repeat interpretation.

The suffix in medical terminology provides information about a condition, procedure, disorder, or disease. The term " neuralgia " contains the suffix " -algia, " which refers to pain, indicating a painful condition of the nerves. In contrast:

A. malaise has no identifiable suffix related to a specific medical condition or disease.

B. ambidextrous has no suffix indicating a disease, condition, or procedure.

D. hypotension includes the prefix " hypo- " (indicating low), but the core term " tension " refers to pressure without an additional suffix specific to condition.

Thus, " neuralgia " is the correct answer as it directly includes a suffix ( " -algia " ) that denotes a pain-related condition in medical terms.

The clinical scenario involves a diagnostic angiography (not separately reportable in this case as the therapeutic intervention occurs in the same session and the diagnosis is already known) and a percutaneous transluminal angioplasty (PTA) with stent placement in the left iliac artery.

To code this correctly:

CPT Code 37267: Transluminal stent placement(s), includes angioplasty within the same vessel, when performed; iliac artery.

This code includes the angioplasty if it is performed in the same vessel as the stent (which is true here — both procedures are done in the left iliac artery).

Since angioplasty is inherent to the stenting (to open the narrowed vessel before stent placement), only the stent code is reported.

No need to report angioplasty separately (e.g., 37263) when performed in the same vessel as the stent.

Other options explained:

A. 37267, 37263 – Incorrect. 37263 (angioplasty in the iliac artery) would only be reported if angioplasty was done in a separate iliac artery segment without stenting. Reporting both codes for the same vessel would be unbundling and against CPT/NCCI guidelines.

B. 37258, 37254 – Incorrect. These codes relate to renal artery procedures, not iliac artery.

C. 37258 – Also incorrect, as this refers to renal stent placement, not iliac.

Official CPT® Guideline Reference:

In the CPT® manual (Category I codes, 37220–37235), specific instructions state that angioplasty is included when performed in the same vessel as a stent and should not be reported separately.

This scenario describesconjunctival provocation testing: an allergenic extract is placed into theconjunctival mucous membraneof the eye and the patient is observed for a localized allergic response (redness, itching, tearing). CPT95060is the code that representsconjunctival (ophthalmic) allergy testing/provocation. The distractors are other allergy testing codes that do not match the site and method described. For CPC exam logic, the key is identifying theroute/siteof allergen exposure: not intradermal (skin), not percutaneous prick, not inhalation/bronchial challenge—this is specificallyocular mucosal testing. The wording “introduced into the mucous membrane inner lining of the eye” is the classic cue. Also note that the code selection is driven by thetype of test, not the suspected diagnosis alone. Therefore, conjunctival provocation testing is correctly reported with95060, and the other options represent different categories of allergy testing or challenge methods.

The urinalysis performed is described asautomated, without microscopy, which corresponds to CPT81003(urinalysis, automated, without microscopy). CPT81001includes microscopy and is not supported because the question explicitly states “without microscopy.” For diagnosis coding, the providersuspecteda UTI, but the urinalysis is negative andUTI is ruled outas the final diagnosis. Under ICD-10-CM reporting principles, conditions documented asruled outarenot codedin the outpatient/office setting; instead, you code thesigns and symptomsthat prompted the visit and testing. The symptoms documented aredysuriaandlower abdominal pain, which are coded asR30.0andR10.30(as presented in the answer choices). Therefore, the correct combination is81003withR30.0andR10.30only. CPC exam tip: outpatient “rule out” → codesymptoms, not the excluded diagnosis.

When hypertension and chronic kidney disease (CKD) are documented together, ICD-10-CM assumes a cause-and-effect relationship.

I12.9 = Hypertensive chronic kidney disease with stage 1–4 CKD

N18.2 = CKD stage 2

I12.0 is only for CKD stage 5 or ESRD, which does not apply here.

Therefore, the correct code combination is I12.9, N18.2.

Procedure Coding (CPT®):

33533 – CABG, arterial graft; single arterial graft (LIMA to LAD)

Correct for left internal mammary artery → LAD

33519 – CABG, venous grafts; three coronary venous grafts

Saphenous vein grafts placed to:

Obtuse marginal

Ramus intermedius

Posterior descending artery

Total = 3 venous grafts

33508 – Endoscopic harvest of saphenous vein

Separately reportable only when endoscopic

Add-on code (no modifier required)

Why Other Options Are Incorrect:

A / C – Incorrect arterial graft code (33536 = multiple arterial grafts)

B – Incorrect venous graft count (33512 = two grafts)

CPT® Guideline Reference:

CABG codes are selected based on:

Type of conduit (arterial vs venous)

Number of distal anastomoses

Endoscopic harvest is add-on and separately reportable

For a patient with type 1 diabetes mellitus and diabetic retinopathy with macular edema in the right eye, the correct ICD-10-CM code is E10.3511. This code specifically captures:

E10: Type 1 diabetes mellitus.

35: Diabetic retinopathy with macular edema.

1: Right eye.

Each choice addresses different severities or eye specifications:

A. E10.3211: Indicates mild nonproliferative diabetic retinopathy with macular edema in the right eye, not the general diabetic retinopathy category.

B. E10.3519: Refers to diabetic retinopathy with macular edema without specification to the right eye.

D. E10.311: Refers to nonproliferative diabetic retinopathy without macular edema in the right eye.

Thus, the correct answer is C. E10.3511, as it fully captures type 1 diabetes with diabetic retinopathy with macular edema in the right eye.

Emergency department visit with high severity

99285 = High complexity ED E/M

The scenario involves a secondary repair of two flexor tendons in the forearm. CPT® code 25272 describes the repair of a secondary flexor tendon injury, including a graft, in the forearm and/or wrist, which fits the description provided. This code should be reported once, as the procedure encompasses the repair of multiple tendons.

93000 = ECG with tracing, interpretation, and report

93010 = Interpretation only

29827: Arthroscopic rotator cuff repair is correctly coded as 29827.

29828: Arthroscopic biceps tenodesis is an additional procedure and should be coded as 29828 with modifier -51 (Multiple Procedures).

29824: Arthroscopic claviculectomy (partial resection of the distal clavicle) is coded as 29824 with modifier -51.

29826: Arthroscopic subacromial decompression, including coracoacromial ligament release, is coded as 29826.

All these procedures were performed arthroscopically and documented in the operative report, justifying the use of these codes and the use of modifier -51 for multiple procedures.

CPT® Professional Edition, AMA

The procedure documented is a modified Fontan procedure → 33615 (Fontan-type single-ventricle repair per the choices given).

The congenital diagnosis documented is double inlet ventricle → Q20.2.

Why the other options are incorrect based on the statements provided:

Q20.4 is not “double inlet ventricle” as stated in the question.

Adding Q20.1 is not supported by the documentation (the question only states double inlet ventricle).

Therefore, the best match is 33615, Q20.2 → A.

This question is testing recognition of amaxillofacial prosthetic servicerather than an ophthalmology procedure code. The vignette describesfabrication of a prosthesis using silicone materialswithmodificationsintended to restorecosmetic appearanceafter loss/damage of an eye. Among the provided options,21086is the CPT code that corresponds to fabrication of afacial prosthesis(commonly silicone-based) with the intent of external restoration. The other codes in this small cluster represent different facial/craniofacial repair or prosthetic services and do not match silicone prosthesis fabrication described in the scenario. CPC exam technique: focus on the key nouns—“fabricates a prosthesis,” “silicon materials,” “cosmetic appearance restoration”—which point away from repair codes and towardprosthetic fabrication. Also note the question is not about insertion of an ocular implant during enucleation/evisceration, but about crafting an external prosthetic device. Therefore, the correct selection is21086.

Injection of atropine: Atropine is administered to reduce sialorrhea.

Bilateral submandibular salivary glands: The physician administers the injections into the salivary glands.

Total of four glands: Indicates that multiple glands are treated in the same session.

CPT code 64611 accurately represents chemodenervation of the salivary glands, bilateral. The use of -50, -52, or x4 modifiers is not appropriate since CPT guidelines include bilateral procedures in this code without needing additional modifiers or codes.

Cesarean Delivery with Antepartum and Postpartum Care: The procedure involved the cesarean section delivery of twins, including antepartum and postpartum care.

CPT Code 59510: This code is used for routine obstetric care including antepartum care, cesarean delivery, and postpartum care. The code is not reported per fetus but per delivery, even when delivering multiples.

1. Procedure and CPT® Code Selection:

The patient underwent a percutaneous needle biopsy of the liver with ultrasound guidance to assess primary biliary cirrhosis.

Code 47000 is the CPT® code for a percutaneous liver biopsy. This code encompasses the biopsy procedure itself.

Ultrasound guidance is commonly inherent to biopsy procedures, and guidance is not separately reported if the main code (47000) includes the technique used.

2. Diagnosis and ICD-10-CM Code Selection:

ICD-10-CM Code K74.5 is the correct code for primary biliary cirrhosis, which is specifically indicated in this case.

K74.3 is the code for other specified cirrhosis of the liver but is less specific than K74.5, making K74.5 the appropriate choice here.

3. Exclusion of Other Codes:

Code 47100 (option A) is for an open liver biopsy, which does not apply to this percutaneous procedure.

Codes 10005 (biopsy with imaging guidance) and 76942 (ultrasound guidance) would be redundant or incorrect since the main procedure code, 47000, sufficiently describes a percutaneous liver biopsy.

4. AAPC and CPT® Coding Guidelines:

AAPC guidelines state that guidance is included in certain biopsy codes when performed for the targeted organ, such as in 47000 for a liver biopsy.

Therefore, based on CPT® and ICD-10-CM coding rules, the correct answer is C. 47000, K74.5.

The National Correct Coding Initiative (NCCI) was developed by CMS to:

Prevent unbundling

Define procedure-to-procedure (PTP) edits

Identify when modifiers (such as -59) may be appropriate

NCCI edits are critical for accurate CPT® coding and proper reimbursement.

69642 = Tympanoplasty with mastoidectomy and ossicular chain reconstruction

Other codes represent variations without ossicular reconstruction or canal wall work

56633 = Radical partial vulvectomy

Deep subcutaneous tissue involvement = radical, not simple

VIN II is coded as D07.1 (carcinoma in situ of vulva) per ICD-10-CM guidelines

Lesion excision codes in the CPT® codebook include the removal of the lesion along with the necessary margins and a simple (nonlayered) closure when performed. These codes do not cover intermediate or complex closures, which are reported separately if performed. The measurement for selecting the appropriate lesion excision code includes the lesion and the margins required for complete excision.

AMA ' s CPT® Professional Edition, lesion excision guidelines.

For the injections, CPT® code 64642 is used for chemodenervation of one extremity; 64643 for each additional extremity, and 64647 for chemodenervation of muscles in the paraspinal region. The modifier -50 is added to 64642 and 64643 to indicate bilateral procedures. According to CPT® guidelines, when multiple sites are treated, each site is coded separately, and appropriate modifiers are used.

AMA ' s CPT® Professional Edition (current year), Surgery section, Nervous System.

1. Procedure and CPT® Code Selection:

The patient requires a surgical nasal sinus endoscopy to repair a cerebrospinal fluid (CSF) leak caused by a skull fracture that resulted in CSF draining into the nasal passage.

Code 31291 is the correct CPT® code for an endoscopic repair of a cerebrospinal fluid leak in the sphenoid sinus. This procedure code is appropriate because it specifically addresses surgical endoscopy for CSF leak repair in the sinus region.

Other codes provided, such as 31287 (nasal/sinus endoscopy with balloon dilation) and 31235 (nasal endoscopy with biopsy), do not match the description for surgical repair of a CSF leak and are therefore inappropriate for this case.

2. Diagnosis and ICD-10-CM Code Selection:

ICD-10-CM Code S02.19XA is used to describe a fracture of the anterior cranial base, which fits the described injury of the skull with cerebrospinal fluid leakage.

External cause code V47.5XXA is used for motor vehicle accidents involving a car hitting a stationary object.

Y92.411 is the appropriate code to describe the location of the accident as a highway.

3. Exclusion of Additional Procedure Codes:

There is no need for a second endoscopy code or a modifier, as 31291 fully describes the endoscopic repair procedure for the CSF leak.

4. AAPC and CPT® Coding Guidelines:

Per AAPC guidelines, procedure codes for sinus endoscopy are chosen based on the specific type of intervention (e.g., CSF leak repair). The guidelines for ICD-10-CM stress including external cause codes and location codes for trauma cases related to motor vehicle accidents.

Thus, the correct answer based on CPT® and ICD-10-CM coding standards is B. 31291, S02.19XA, V47.5XXA, Y92.411.

ICD-10-CM has a clear hierarchy when the same substance is documented with multiple levels of severity.Dependencerepresents a higher severity classification thanabuse, andabuseis higher thanuse. When two or more of these are documented for the same substance, you generally assignonly one code, selecting thehighest level of severitysupported: dependence over abuse, and abuse over use. Therefore, if bothuse and dependenceare documented, you assigndependence only(Option D). Option A is incorrect because you do not code both use and abuse for the same substance; you choose the higher severity (abuse). Option B is incorrect because if abuse and dependence are both documented, you would codedependence, not abuse. Option C is incorrect because ICD-10-CM does not support reporting all three separately for the same substance; doing so would be duplicative and noncompliant. CPC exam tip: remember the mnemonicD-A-U→Dependence > Abuse > Use(pick the highest).

Anesthesiaphysical status modifiersare the ASA modifiersP1–P6, which describe the patient’s overall systemic health (e.g., P1 = normal healthy patient; P2 = mild systemic disease; up to P6 = brain-dead patient whose organs are being removed for donor purposes). Among the choices,P1is the only ASA physical status modifier.QSis an anesthesia modifier indicatingMonitored Anesthesia Care (MAC), not physical status.AAidentifies the anesthesia service performedpersonally by an anesthesiologist, which is a provider/service modifier, not a physical status.2Pis not an ASA physical status modifier; physical status modifiers are specifically formatted asP1–P6. CPC exam tip: separate anesthesia modifiers into categories: (1)physical status(P1–P6), (2)who provided/medical direction(AA, QK, QX, QY, etc.), and (3)service circumstancemodifiers (like QS for MAC when applicable). Here, the question explicitly asks for physical status—soP1is correct.

Selective catheter placement coding follows thehighest-order selective catheterization achievedwithin a vascular family, plus additional selective placements when adifferent vascular familyis entered. Here, access is via femoral artery into theabdominal aorta(nonselective aortic position), then selective advancement into theleft inferior phrenicand further into theleft superior suprarenal (adrenal) artery. The code set offered indicates reporting36245(selective, first-order or initial selective placement as represented by the item’s structure) and36246(additional selective advancement). Imaging is also reported:75731represents the angiographic imaging component matching the described abdominal/visceral angiography in the options. Options with-50are incorrect because the study is on theleftside only, not bilateral. Option C omits a necessary catheter placement level from the option set, and option D substitutes a different catheter placement code while still incorrectly using bilateral imaging. Therefore, optionAbest reflects the catheter placement progression and associated angiography per the question’s choices.

Basal cell carcinoma is amalignantskin neoplasm, so the excision is coded from11600–11646(malignant lesion excision), not11400–11446(benign lesion excision). The scalp is in the anatomic group that includesscalp/neck/hands/feet/genitalia, and the excised diameterincluding marginsdetermines the malignant excision code range. A size of3.7 cmfalls into the3.1–4.0 cmcategory, which corresponds to11624for malignant excision in that location group. Closure is separately reportable when it is anintermediate (layered) repair, so you add12032(intermediate repair, scalp/axillae/trunk/extremities;2.6–7.5 cm) when documentation supports layered closure beyond simple repair. Diagnosis coding should reflectbasal cell carcinoma of scalp/neck, which isC44.41. Options that use benign excision or benign diagnosis codes are incorrect for basal cell carcinoma.

1. Procedure and CPT® Code Selection:

The emergency department physician placed an indwelling catheter into the lumbar region for continuous infusion for pain management with fluoroscopic guidance.

CPT® Code 62327 is appropriate for injection or catheter placement for continuous infusion of anesthetic or analgesic in the lumbar or sacral region using imaging guidance.

CPT® Code 77003 represents the fluoroscopic guidance used during the catheter placement, which is separately reportable in this case.

2. Rationale for Excluding Other Options:

Code 62326 (in options B and D) is for the injection or catheter placement without imaging guidance. Since fluoroscopic guidance was specifically mentioned, 62327 is the appropriate choice.

Code 77003 must be reported separately when fluoroscopy is used in conjunction with 62327 for pain management catheter placement.

3. AAPC and CPT® Coding Guidelines:

According to AAPC guidelines, the combination of 62327 and 77003 is correct when catheter placement for continuous infusion is performed with fluoroscopic guidance.

Therefore, the correct answer is C. 62327, 77003.

71048 – Radiologic examination, chest; complete, minimum of 4 views

Includes 6 views

CPT codes are based on ranges, not per-view billing

Why Other Options Are Incorrect:

71047 – 2 views only

CPT does not allow “× view” reporting

Procedure: Albumin Cobalt Binding (ACB) test to determine ischemic nature of chest pain.

CPT® Code:

83857: This code is used for the Albumin Cobalt Binding test.

Code Selection Justification: The ACB test specifically measures ischemia-modified albumin, making 83857 the appropriate code for this laboratory test.

CPT® code 36252 describes selective catheter placement of the main renal artery with angiography of both kidneys, which matches the procedure of selectively catheterizing the right and left renal arteries and performing angiography. Additionally, CPT® code 75625-26 is for an abdominal aortography with interpretation and report. The -26 modifier indicates that the professional component of the service was performed.

Burn coding requires (1) code each burn site bylocation, laterality, and degree, and (2) add aTBSAcode when appropriate. The patient hasthird-degree burnsof both thighs (right and left), so the correct site/degree codes areT24.311A(third-degree burn of right thigh, initial encounter) andT24.312A(third-degree burn of left thigh, initial encounter). He also hassecond-degree burnsof the right anterior chest wall and the upper back, reported withT21.21XA(second-degree burn of chest wall, initial encounter) andT21.23XA(second-degree burn of back wall, initial encounter). TBSA is24%(falls in the 20–29% category), andthird-degree is 10%(falls in the 10–19% third-degree category), so the correct TBSA code isT31.21. Option D matches the required site/degree codes and the correct TBSA/third-degree percentage code pairing.

The CPT code 12002 is used for simple repair of superficial wounds of 2.5 cm or less. This code includes the repair of both the 3 cm laceration on the right arm and the 2 cm laceration on the nose as both are simple repairs. The other options suggest more complex repairs or multiple separate procedures, which are not necessary in this scenario.

AMA ' s CPT® Professional Edition (current year)

Formultiple gestation vaginal deliveries, CPT global obstetric care is generally reported as the global code for thefirst fetus(here59400: antepartum + vaginal delivery + postpartum), and an additionaldelivery-onlycode for each additional fetus (here59409) with an appropriate modifier (commonly-51in exam-style choices). You donotreport59400 twicebecause the global package is not duplicated for each baby; only the additional delivery service is added for the additional fetus. Diagnosis coding: this is atwin pregnancy, dichorionic/diamniotic, third trimester→O30.043. Delivery outcome for twins →Z37.2, and weeks of gestation →Z3A.36. Because delivery occurred at36 weeks(preterm threshold is < 37 weeks), and the options use thepreterm labor with preterm deliverycategory with fetus identifiers, the correct pairing shown isO60.14X1 and O60.14X2(fetus 1 and fetus 2). Option D is the only one matching correct CPT multiple-delivery structure and appropriate diagnosis set.

1. Procedure and CPT® Code Selection:

The patient underwent a needle biopsy of the liver using CT guidance to obtain two core biopsy samples.

CPT® Code 47000 is for a percutaneous needle biopsy of the liver, which covers the liver biopsy procedure.

CPT® Code 77012 is the correct code for CT guidance for needle placement in soft tissue, which includes the guidance required to obtain accurate liver biopsy samples.

2. Rationale for Excluding Other Options:

Code 47001 in option A is an add-on code for a liver biopsy performed during another procedure (such as a laparoscopic or open procedure) and is not applicable in this case, as 47000 is sufficient for a percutaneous approach.

Code 76942 (in option A) represents ultrasound guidance, not CT guidance, and thus is incorrect.

Code 77002 (in option B) is used for fluoroscopic guidance for needle placement, which is not applicable since CT guidance was used.

Option C incorrectly includes 47001, which is not needed as 47000 fully covers the percutaneous needle biopsy.

3. AAPC and CPT® Coding Guidelines:

According to AAPC guidelines, 47000 is used for percutaneous liver biopsies, and 77012 should be reported for CT guidance for needle placement in the liver.

Therefore, the correct answer is D. 47000, 77012.

The outermost protective layer of the skin is called the epidermis. It serves as a barrier to protect the body against environmental elements, pathogens, and helps to retain moisture. The epidermis itself is composed of several sub-layers, with the stratum corneum being the outermost layer.

00537 – Anesthesia for electrophysiologic procedures including ablation

Patient is otherwise healthy → P1

Why others are incorrect:

1. Procedure and CPT® Code Selection:

The patient underwent a partial nephrectomy (removal of part of the left kidney) via a laparoscopic approach.

CPT® Code 50543 is specifically used for a laparoscopic partial nephrectomy, which is an accurate description of this procedure.

2. Rationale for Excluding Other Options:

Code 50548 is used for a laparoscopic radical nephrectomy, which involves the complete removal of the kidney and surrounding structures; therefore, it does not apply to this partial nephrectomy.

Code 50220 represents an open partial nephrectomy, not a laparoscopic approach, and is therefore incorrect for this procedure.

Code 50546 is for a laparoscopic radical nephrectomy with bilateral removal of kidneys, which is not applicable in this case where only a partial removal of the left kidney was performed.

3. AAPC and CPT® Coding Guidelines:

AAPC and CPT® guidelines indicate that the use of 50543 is appropriate for any laparoscopic partial nephrectomy, regardless of the laterality, and it specifically identifies laparoscopic technique over open surgery.

Therefore, based on CPT® guidelines, the correct answer is C. 50543.

Dacryocystitis is the inflammation of the lacrimal sac, which is part of the tear drainage system located in the inner corner of the eye. The lacrimal sac is connected to the nasolacrimal duct, which drains tears into the nasal cavity. Inflammation in this area can cause pain, redness, and swelling near the inner corner of the eye.

ICD-10-CM, medical dictionaries

When a prior malignancy has been eradicated and the patient is no longer receiving treatment for the primary site, ICD-10-CM directs you to use apersonal history of malignant neoplasmcode rather than an active primary cancer code. Here, the breast cancer was treated successfully last year and no further therapy was required, so the breast cancer ishistory, not active. The new current condition ismetastatic cancer to the liver, which is coded as asecondary malignant neoplasm of liver and intrahepatic bile duct (C78.7). Because the primary breast cancer is not documented as active or under current treatment, you donotcode an active breast malignancy (C50.-). Instead, you addZ85.3 (personal history of malignant neoplasm of breast)to show the prior cancer history relevant to the current metastatic disease. Option A incorrectly codes a primary liver cancer. Option C incorrectly codes active breast cancer. Option D codes metastasis to the adrenal gland, not the liver.

1. Procedure and CPT® Code Selection:

The patient underwent an appendectomy performed via laparoscopic approach. The procedure involved removal of the appendix using a scope inserted through an umbilical incision.

CPT® Code 44970 is specific for a laparoscopic appendectomy, which is the correct code for this procedure.

Code 44950 would be used for an open appendectomy, but since this case was performed laparoscopically, 44970 is appropriate.

2. Diagnosis and ICD-10-CM Code Selection:

The diagnosis given by the physician is chronic appendicitis.

ICD-10-CM Code K36 is used to report chronic appendicitis, which is the definitive diagnosis in this case.

Additional codes for symptoms such as nausea (R11.2) and right lower quadrant pain (R10.31) are not necessary because the primary diagnosis of chronic appendicitis (K36) fully explains the symptoms, according to ICD-10-CM guidelines on coding symptoms when a definitive diagnosis is available.

3. AAPC and CPT® Coding Guidelines:

AAPC guidelines indicate that when a definitive diagnosis is established, symptom codes should not be reported separately. The use of 44970 for laparoscopic appendectomy and K36 for chronic appendicitis is fully supported by these coding standards.

Therefore, the correct answer is C. 44970, K36.

60220 = Total lobectomy, unilateral thyroid

60500 = Parathyroidectomy (single gland)

Modifier -59 is appropriate to indicate a distinct procedure

1. Procedure and CPT® Code Selection:

The procedure performed was a hysteroscopy to examine the uterine cavity due to abnormal vaginal bleeding. This is a diagnostic hysteroscopy.

CPT® Code 58555 is specifically for a diagnostic hysteroscopy to examine the uterine cavity, which aligns with the procedure performed in this case.

2. Rationale for Excluding Other Options:

Code 58558 is for a hysteroscopy with a surgical procedure, such as biopsy or removal of a lesion or polyp, which was not performed in this case.

Code 58579 is an unlisted procedure code for the female genital system and is unnecessary here because there is a specific code (58555) for diagnostic hysteroscopy.

Code 58578 is also an unlisted hysteroscopic procedure code and is not appropriate when a specific diagnostic code exists.

3. AAPC and CPT® Coding Guidelines:

AAPC guidelines indicate that 58555 should be used for diagnostic hysteroscopy procedures without any surgical intervention.

Therefore, the correct answer, following CPT® guidelines, is C. 58555.

54160 = Circumcision using surgical excision other than clamp

Modifier -63 is not appended to circumcision codes (CPT® exempt list)

54150 is for clamp technique (not used)

Frozen section pathology coding rules:

88331 – Frozen section, first tissue block, each specimen

88332 – Frozen section, each additional tissue block, same specimen

Breakdown:

Specimen 1

Block 1 → 88331 × 1

Block 2 → 88332 × 1

Specimen 2

Block 1 → 88331 × 1

Block 2 → 88332 × 1

However, multiple frozen sections per tissue block are separately reportable:

Total first blocks = 4 frozen sections → 88331 × 4

Total additional blocks = 3 frozen sections → 88332 × 3

CPT® pathology guidelines require coding by tissue block and specimen, not by polyp alone.

20552 = Injection(s); single or multiple trigger points, 1–2 muscles

Total muscles injected = 2 (trapezius + pectoralis)

Number of injections does not determine code selection—number of muscles does

This procedure is not a simple diagnostic lumbar puncture; it includestherapeutic drainageof CSF to relieve elevated intracranial pressure. CPT62272is used forspinal puncture with drainage of cerebrospinal fluid(therapeutic), which matches the “actively drain CSF” language. The physician also performed the puncture underCT guidance, and when imaging guidance is documented and not bundled into the primary code, you report the appropriate CT guidance code77012for needle placement. Option D (62270) is the classic diagnostic lumbar puncture/spinal puncture code and does not capture active drainage as the purpose. Options A and B are for different catheter/needle procedures and do not best match “spinal puncture with drainage” plus CT guidance in this vignette. CPC exam tip: when the stem emphasizespressure relief/drainage, thinktherapeutic drainage coderather than diagnostic LP, and then add imaging guidance when specifically documented and supported.

Frozen section pathology coding rules:

88331 – Frozen section, first tissue block, each specimen

88332 – Frozen section, each additional tissue block, same specimen

Breakdown:

Specimen 1

Block 1 → 88331 × 1

Block 2 → 88332 × 1

Specimen 2

Block 1 → 88331 × 1

Block 2 → 88332 × 1

However, multiple frozen sections per tissue block are separately reportable:

Total first blocks = 4 frozen sections → 88331 × 4

Total additional blocks = 3 frozen sections → 88332 × 3

CPT® pathology guidelines require coding by tissue block and specimen, not by polyp alone.

1. E/M Service Code Selection:

On day two, the urologist provided an evaluation and management (E/M) service for a hospitalized patient with a low level for the number and complexity of problems addressed, minimal complexity for data reviewed, and moderate risk of complications.

CPT® Code 99232 is for a subsequent hospital care E/M service with a level of " Expanded Problem Focused " history and examination, with Medical Decision Making (MDM) of Moderate complexity. This matches the description provided, as the MDM includes a low number of problems, minimal data, and moderate risk.

2. Rationale for Excluding Other Options:

Code 99233 is for a subsequent hospital care visit with high complexity MDM (e.g., addressing a high number of problems or higher levels of data review), which does not align with the moderate risk described here.

Code 99221 is for initial hospital care, not a subsequent visit.

Code 99231 represents a lower level of subsequent hospital care with straightforward or low complexity MDM, which does not meet the moderate risk criteria in this scenario.

3. AAPC and CPT® Coding Guidelines:

AAPC and CPT® guidelines indicate 99232 as appropriate for subsequent hospital visits with moderate MDM, such as this visit with moderate risk but minimal data complexity.

Therefore, the correct answer is B. 99232.

Pressure ulcer excision with bone involvement → CPT 15937 (sacral, with ostectomy)

Stage 4 pressure ulcer → L89.156 (sacral region with necrosis of bone)

62272 = Lumbar puncture with catheter for CSF drainage

77012 = CT guidance for needle placement

Brackets [ ] in the ICD-10-CM Alphabetic Index are used to identify manifestation codes.

These codes cannot be reported as the principal diagnosis and must be sequenced after the underlying condition.

This is a frequently tested ICD-10-CM guideline concept.

CABG coding is based on the number of conduits, not distal anastomoses

33533 = single arterial graft (IMA)

33518 is incorrectly listed here but is the closest exam-supported option

The gallbladder is part of the digestive system. It stores and concentrates bile, which aids in the digestion of fats.

It works closely with the liver and biliary tract, all of which belong to the digestive system, making C the correct answer.

Procedure: Caloric vestibular testing performed on both ears with three irrigations.

CPT® Code:

92537: Caloric vestibular test with recording, bilateral; bithermal (i.e., one warm and one cool irrigation in each ear).

Modifier -50: Bilateral procedure.

Code Selection Justification: The procedure performed was bilateral caloric vestibular testing with bithermal irrigation, appropriately coded with 92537 and modifier -50 for bilateral procedures.

AMA CPT® Professional Edition (current year)

This scenario describes an anterior discectomy and arthroplasty at two levels (L3-L4 and L5-S1) using artificial discs. CPT® code 22857 describes total disc arthroplasty (artificial disc), anterior approach, including discectomy to prepare interspace (other than for decompression), single interspace, lumbar. Since the procedure was performed at two levels, the code should be reported twice.

CPT code 99450 is used for the examination of a patient for the purpose of establishing medical baseline information or for insurance purposes. Since Eric ' s primary care provider completed the required physical exam documentation for his life insurance policy, this is appropriately reported with code 99450. References: CPT® Professional Edition (current year), AMA.

TSH testing is reported with CPT84443. The scenario describes a workup for possible thyroid dysfunction, but there isno confirmed thyroid diagnosisprovided—only symptoms (fatigue and weight gain). In outpatient coding, when a definitive diagnosis is not established, you code thesigns/symptomsthat justify the test. Therefore, the correct ICD-10-CM codes areR53.83(other fatigue) andR63.5(abnormal weight gain), as offered. You shouldnotassign a thyroid disorder code such asE07.9(unspecified disorder of thyroid) unless the provider documents an actual thyroid disorder diagnosis; suspicion alone does not support it in the outpatient setting. Options C and D list84445, which is not the standard CPT code for TSH measurement in CPC exam coding. This question is testing both correct lab code selection and the outpatient guideline principle of codingsymptomswhen the diagnosis is not confirmed. Hence,84443 with R53.83 and R63.5is correct.

1. Procedure and CPT® Code Selection:

The patient had a cochlear implant placed in the left ear and is now seeing the audiologist for initialization and programming of the implant.

CPT® Code 92603 is specific for initial programming of a cochlear implant for patients younger than 12 years old. This includes the setup and initial adjustments required for the cochlear implant, making it the correct code.

2. Rationale for Excluding Other Options:

Code 92626 is used for evaluating auditory function with the cochlear implant, focusing on assessment rather than programming, and is therefore incorrect for this programming session.

Code 92630 is for aural rehabilitation following cochlear implant, which does not apply to the programming/initiation stage.

Code 92604 is for subsequent programming sessions after the initial programming and is therefore not applicable for the first-time programming.

3. AAPC and CPT® Coding Guidelines:

According to AAPC guidelines, 92603 is the appropriate code for initial programming of a cochlear implant in children under 12 years of age.

Therefore, the correct answer is D. 92603.

IV hydration is coded byduration. CPT96360is forinitial intravenous hydration(typically the first hour). CPT96361is an add-on code foreach additional hourbeyond the initial hour, reported when the hydration time exceeds 60 minutes and meets the additional-hour threshold. The scenario documents hydration for1 hour and 30 minutes (90 minutes). That supports reporting theinitial hour(96360) plusone additional hour(96361) because the infusion extends beyond the initial hour and reaches the qualifying threshold for an additional hour as defined by CPT time rules (time is rounded/assigned based on midpoints, not per minute). The other options usetherapeutic infusioncodes (96365/96366), which are for medications/drugs, not for hydration with normal saline when the primary purpose is hydration. CPC exam tip: if the service is specifically “hydration” and the fluid is normal saline for dehydration/heat exhaustion, use96360/96361and apply time-based logic.

This operative note describes two major components: (1)revision mastoid surgeryto treat chronic infection/osteomyelitis and remove diseased tissue, and (2)replacement/placement of a BAHA osseointegrated implantin a new location. In the answer set,69502-RTrepresents the revision mastoidectomy-type service (appropriate because this is not a first-time mastoidectomy and includes significant revision/debridement work).69714-RTrepresents theimplantation of an osseointegrated skull devicesuch as a BAHA. The case uses magnifying loupes, not an operating microscope, so69990is not supported; CPT 69990 requires anoperating microscope(explicitly documented), and loupes alone do not meet that threshold. Options using 69717 do not match the described implant service in this question’s choices. Therefore, the correct reporting per the options is69502-RT and 69714-RT.

Pregnancy guidelines require O codes first.

O98.513 = COVID-19 infection complicating pregnancy, third trimester

U07.1 = COVID-19

Z3A.32 = 32 weeks gestation

Symptoms (SOB, fever) are not coded separately when integral to COVID-19.

Correct sequencing makes A correct.

24300 = Manipulation of elbow under anesthesia

Anesthesia codes (01710) are not reported by the surgeon, only by the anesthesiologist

24605 is for closed treatment of elbow dislocation, which is not documented

Medical terms here are very literal.Peri-meansaround,cardirefers to theheart, and-itismeansinflammation. Sopericarditisis inflammation of thepericardium, thefibrous sac surrounding the heart. “With effusion” indicatesfluid accumulationin that pericardial space (pericardial effusion), which can be clinically important because significant effusion may impair heart filling (tamponade risk), but the question is strictly asking which structure is inflamed. Distractors map to other “card-” terms:myocardium(heart muscle) would be “myocarditis,”endocardium(inner lining of chambers/valves) would be “endocarditis,” and blood vessels supplying the heart arecoronary arteries(inflammation would not be termed pericarditis). On CPC exams, identifyingprefix + root + suffixis the fastest method: peri (around) + cardi (heart) + itis (inflammation) → pericardium inflamed.

To select the correct HCPCS Level II code for a non-emergency ambulance service, we focus on the following components:

A0428 represents " Ambulance service, Basic Life Support (BLS), non-emergency transport, " which is appropriate here as the patient was transported with non-emergency BLS following a fainting episode. This eliminates options B and D, which indicate " emergency " (A0429).

QM Modifier indicates " Ambulance service provided under arrangement by a provider of services, " relevant when a physician arranges the ambulance transport.

PH Modifier specifies " Physician’s office to hospital " transport, matching the scenario where the patient was taken from the physician’s office to the hospital.

Thus, A0428-QM-PH accurately describes a non-emergency BLS transport arranged by a provider from a physician ' s office to the hospital, aligning with choice A.

Warthin ' s tumor, also known as papillary cystadenoma lymphomatosum, is a benign tumor of the salivary glands, most commonly affecting the parotid gland. It typically presents as a painless, slow-growing mass near the angle of the jaw.

For the procedure involving access to the subclavian vein and advancing a catheter to the inferior vena cava for injection and imaging, the following codes are used:

36010 for the catheter placement.

75825-26 for the supervision and interpretation of the imaging.

Modifier -26 indicates the professional component of the radiological supervision and interpretation.

The place of service code 22 is used for services performed in an outpatient hospital setting, including outpatient surgical floors. This code indicates that the procedure was done in a hospital but not requiring an inpatient admission.

AMA ' s CPT® Professional Edition (current year), Place of Service Codes.

Chest radiography codes are selected by thenumber of viewsperformed. CPT71047is for chest X-ray with2 views, while71048is for chest X-ray with3 or 4 views. When the number of views exceeds a code’s defined range, you generally donotreport the code multiple times per extra view; instead, you select the CPT code that best describes the service family and view count as structured by the code set and payer rules. In CPC-style question design, “6 views of the chest” is often included to test whether you incorrectly multiply per view. The answer options provided do not include a dedicated “6+ view chest” code, and the correct choice in this question’s answer set is to report71048(the higher view-count chest radiograph code offered)once, not “×6” or doubling 2-view codes. Option A and B reflect incorrect per-view/per-unit reporting. Therefore, within the provided choices, the correct answer is71048.

This is anestablished patient office visitcoded byMDM(or time, but time is not provided). Problems:one acute, uncomplicated illness(URI) → supportslowproblem complexity. Data: no labs/imaging ordered or reviewed →minimal/nonedata. Risk: although a prescription is given, MDM level is determined by2 of 3elements (Problems, Data, Risk). Here, only the risk might approach moderate due to prescription management, butproblems and data remain low/minimal, so the overall MDM doesnotmeet moderate. Therefore, the visit is best supported atlow MDM, which corresponds to99213for an established patient. It is more than minimal (99212) because a focused exam and management plan are documented, but it does not meet the higher complexity required for 99214/99215 (multiple problems, significant data review, or high-risk management). CPC exam focus: don’t let a single element (like antibiotics) automatically “force” a higher code—MDM requires meeting the level intwo elements.

This is arepeatdecompression at apreviously operatedlumbar level, described as “repeat exploration laminotomy,” which aligns with there-explorationcode family rather than a primary discectomy code. The procedure includesbilateral foraminotomyat a single lumbar interspace (L1–L2), meaning it is performed onboth sidesat the same level. In the answer choices,63042represents re-exploration/decompression (repeat procedure) and is appropriately markedbilateralwith-50. The foraminotomy component at the lumbar level is represented by63044, also performed bilaterally, so63044-50is appropriate when the code is unilateral by descriptor and the work was done on both sides. Options C and D reference63030/63035, which are associated with lumbar discectomy/decompression primary coding patterns, not the “repeat exploration laminotomy” scenario presented. Option A incorrectly lists 63044 twice rather than using bilateral reporting. Therefore,63042-50, 63044-50is the best match within the provided options.

55970 = Female-to-male sex transformation

55980 is for male-to-female transformation

Unlisted codes (58999, 55899) are not used when a specific CPT® code exists

In medical terminology, the suffix -graph refers to an instrument used for recording data or the process of recording. This suffix is commonly tested on the CPC exam.

Examples include:

Electrocardiograph – instrument used to record heart activity

Angiograph – instrument used to record images of blood vessels

To distinguish from related suffixes:

-gram = the record or image itself

-graphy = the process of recording

Thus, option A is correct.

Observation E/M coding is chosen by thetype of serviceprovided on each calendar date. Day 1 includes initiation of observation with significant work (IV insulin drip, multiple labs, discussion with endocrinologist), supporting an observation initial care code. In this option set,99235represents an observation “admit and discharge on same date” style service; however, the patient stays multiple days. The question’s answer choices are structured around using99235as the initial observation care code offered, then a subsequent observation code for day 2, and a discharge code for day 3. Day 2 includes ongoing management with documented time of 25 minutes, supporting asubsequent observation carecode such as99231(as provided). Day 3 isobservation discharge, which is99238(30 minutes or less) given the documented 15 minutes. While the most current observation framework in CPT has evolved, the CPC-style expected pattern in these choices is99235 (initial), 99231 (subsequent), 99238 (discharge). Therefore, optionBmatches the intended coding sequence across the observation stay dates.

In CPT® fracture and dislocation care, manipulation refers to the application of force or traction to restore a bone or joint to its normal anatomic position.

This is a key distinction between with manipulation and without manipulation, which directly affects CPT code selection (e.g., 23505 vs. 23500).

Manipulation may be performed closed (no incision) or open (with incision).

1. Procedure and CPT® Code Selection:

The otolaryngologist was asked to perform a general otolaryngologic examination of the patient under general anesthesia to evaluate for injuries sustained from a traumatic fall.

CPT® Code 92502 is appropriate for a general otolaryngologic examination under general anesthesia. This code is used specifically when an ENT examination is performed under anesthesia, as was the case here.

2. Rationale for Excluding Other Options:

Code 92512 is for nasal function studies, such as rhinomanometry, which does not apply to a general otolaryngologic examination.

Code 21310 is for the treatment of a nasal fracture (closed treatment), which would only be appropriate if the otolaryngologist had performed a fracture reduction or repair. Since only an examination was performed, 21310 is not appropriate.

Code 92502-51 (option B) is incorrect because the -51 modifier (multiple procedures) is unnecessary; only a single examination was performed.

3. ICD-10-CM Code:

Since only the examination was performed and not treatment, the ICD-10-CM code for nasal fracture (likely S02.2XXA for unspecified fracture of the nasal bones, initial encounter) would be reported separately by the facility or based on final documentation.

4. AAPC and CPT® Coding Guidelines:

AAPC guidelines support the use of 92502 for general ENT examinations performed under anesthesia, especially in cases of trauma evaluation without surgical intervention.

Therefore, the correct answer is D. 92502.

Procedure Coding:

56633 – Radical vulvectomy (removal of > 80%), including deep subcutaneous tissue

Documentation supports greater than 80% vulvar removal

Deep tissue involvement confirms radical procedure

Diagnosis Coding:

D07.1 – Carcinoma in situ of vulva

VIN III = high-grade squamous intraepithelial lesion

Classified as carcinoma in situ, not benign dysplasia

Why Other Options Are Incorrect:

56620 / 56625 / 56630 – Partial or simple vulvectomy

N90.1 – Mild vulvar dysplasia (incorrect severity)

ICD-10-CM Official Guideline:

VIN III is coded as D07.1, not N90.x.

Procedure Coding (CPT®):

44212 – Laparoscopic partial colectomy with end colostomy and closure of distal segment (Hartmann-type procedure)

Correct because:

Sigmoid/descending colon resection

Proximal colostomy created

Distal rectal stump closed

44213 – Laparoscopic mobilization of splenic flexure

Separately reportable because:

Mobilization was necessary to exteriorize colon for colostomy

Not bundled into 44212

Modifier not required (no multiple-procedure discount with add-on logic)

Diagnosis Coding (ICD-10-CM):

K57.33 – Diverticulitis of large intestine with perforation and bleeding, without abscess

Documentation supports:

Diverticulitis

Active bleeding

No abscess reported

Why Other Options Are Incorrect:

A / B – 44206 = colectomy with anastomosis (not performed)

A / B – K57.41 includes abscess (not documented)

C – Missing splenic flexure add-on explanation

CPT® & ICD-10-CM Guideline Alignment:

Hartmann procedure ≠ anastomosis

Bleeding elevates diagnosis specificity

Splenic flexure mobilization is separately reportable when clinically required

Procedure Coding (CPT®):

31287 – Nasal/sinus endoscopy, surgical; with sphenoidotomy

Correct because the surgeon performed a surgical endoscopic sphenoidotomy to evaluate and treat sphenoid sinus injury.

No CSF leak repair was performed, so codes 31290–31291 are not appropriate.

31231-59 – Nasal endoscopy, diagnostic

Diagnostic endoscopy is separately reportable because:

It was performed to evaluate traumatic injury

It is not bundled into the surgical service when it provides distinct diagnostic information

Modifier -59 indicates a separate and distinct service per NCCI edits.

Diagnosis Coding (ICD-10-CM):

S02.109A – Unspecified fracture of base of skull, initial encounter for closed fracture

The anterior cranial fossa fracture with sphenoid sinus involvement qualifies as a skull base fracture

No CSF leak is documented

Correct 7th character “A” for initial encounter

Why Other Options Are Incorrect:

A – Incorrect format and duplicated CPT logic

B – 31267 = maxillary sinus, wrong sinus

D – 31291 includes CSF leak repair, which was not performed

The documented study is atransvaginal pelvic ultrasound, which is coded with76830(ultrasound, transvaginal). Because the service is billed by anindependent radiologist providing only the interpretation, the correct reporting is theprofessional componentwith modifier-26(interpretation and report), not the global code. That makes76830-26the correct CPT selection. Code76817is fortransvaginal ultrasound in pregnancy/obstetric contexts, which is not supported here (the patient is menopausal and no pregnancy evaluation is described). For diagnosis, the chief complaint isuterine cramping, and the options provide pelvic pain codes;N94.89(other specified conditions associated with female genital organs and menstrual cycle) is the best match among the choices provided for uterine cramping/pelvic symptom documentation.N94.9is less specific (“unspecified”), so when a more specific option is available in the answer set, selectN94.89. Therefore, the correct combination for the interpreting independent radiologist is76830-26, N94.89.

1. Procedure and CPT® Code Selection:

The patient underwent a repair of a ruptured aneurysm in the popliteal artery, involving incision, dissection, clamping, removal of the aneurysmal section, and patch grafting.

Code 35151 is the correct CPT® code for the repair of an aneurysm in the popliteal artery, as it specifically describes aneurysm repair in this location.

Code 35081 applies to aneurysm repair in the abdominal aorta, which does not pertain to the popliteal artery location.

Code 35152 is for an aneurysm repair involving the popliteal artery with vein graft, but there is no mention of a vein graft in this scenario, only a patch graft.

Code 35045 is used for repair of an aneurysm in the brachial artery and does not apply to the popliteal artery.

2. AAPC and CPT® Coding Guidelines:

According to AAPC guidelines, CPT® codes for aneurysm repair should be chosen based on the specific artery involved. Code 35151 is precisely for popliteal artery aneurysm repair without a vein graft, making it the most accurate choice.

Thus, based on CPT® guidelines and procedural details, the verified answer is B. 35151.

1. Procedure and CPT® Code Selection:

The cardiologist provided remote monitoring over a 30-day period for a hemodynamic pulmonary artery pressure monitor implanted in a patient with congestive heart failure.

CPT® Code 93264 is appropriate for remote monitoring of a hemodynamic system for up to 30 days. This code includes services such as weekly data transmissions, interpretation, trend analysis, and reporting—exactly as described in this case.

2. Rationale for Excluding Other Options:

Code 93286 is for in-person interrogation and programming of pacemakers or defibrillators, not for remote monitoring of a hemodynamic monitor, making it incorrect.

Code 93288 is for interrogation device evaluation (remote), specifically for pacemakers or defibrillators, and does not apply to a pulmonary artery pressure monitor.

Code 93279 is for in-person programming of certain cardiac devices, which does not match the remote monitoring described in this scenario.

3. AAPC and CPT® Coding Guidelines:

AAPC and CPT® guidelines specify that 93264 is the correct code when reporting remote hemodynamic monitoring for a pulmonary artery pressure device over a period of up to 30 days, including data review and interpretation.

Therefore, the correct answer is B. 93264.

Systematically billing all office visits at a predetermined level—without documentation supporting the requiredmedical decision making (MDM)ortime—is a classic compliance red flag and is generally treated asabuse(often described as upcoding when higher levels are billed than supported). E/M levels must reflect what was actually performed and documented for that encounter, using the E/M rules (MDM elements or total time, depending on code selection). Even if a provider treats complex patients, not every visit will meet the same level; stable follow-ups may be lower complexity than acute exacerbations or new problems. “Waste” generally refers to inefficient or unnecessary use of resources without intent to misrepresent; a blanket instruction to code moderate levels suggestssystematic misbillingrather than inefficiency. Option D is incorrect because providers cannot select any level at will—coding must be supported by documentation. This type of pattern is exactly what audits target, and it can trigger overpayment recoupment, penalties, and corrective action plans.

Codes69209(removal of impacted cerumen by irrigation/lavage) and69210(removal of impacted cerumen requiring instrumentation) are intended forimpacted cerumen, so documentation must support that the wax isimpacted—not merely present. That makes optionBthe most accurate statement. OptionAis incorrect because you generally donotreport both methods for thesame earin the same session; you select the code that reflects the method required for that ear. OptionCis not reliably correct for CPT rules because bilateral reporting for cerumen removal is typically handled using the payer’s bilateral instructions (often modifier50or separate line items depending on payer), not a universal “report twice” instruction. OptionDcan be true in certain circumstances (significant, separately identifiable E/M), but it is not the core parenthetical principle tested here. CPC exam focus: impacted requirement + select the correct method code.

90960 = ESRD services, 4 or more visits/month

N18.6 = End-stage renal disease

Z99.2 = Dependence on renal dialysis

93280 – In-person interrogation device evaluation with programming; dual-chamber pacemaker

Includes:

Full electronic analysis

Lead function

Battery status

Threshold testing

Programming changes

Why others are incorrect:

93281 – Single-chamber pacemaker

93283 / 93284 – ICD device codes

The operative approach is explicitlyopen surgery, so the correct CPT procedure code is44950(appendectomy; open). Code44970is thelaparoscopicappendectomy code and is not supported because the scenario states “open surgery.” For diagnosis, the physician’s final diagnosis ischronic appendicitis, which is reported withK36(other appendicitis) in the context of this question’s choices;K35.80represents acute appendicitis (unspecified acute) and does not match “chronic.” You also do not report symptom codes (nausea/vomiting/abdominal pain) once a definitive diagnosis is established and documented as the reason for the surgery, unless a guideline or scenario specifically requires them as additional reporting (this question does not). Therefore, the correct pairing is44950withK36only. CPC exam tip: always matchapproach(open vs laparoscopic) and code thefinal confirmed diagnosisrather than presenting symptoms when the definitive diagnosis is known.

Esotropia of the right eye: Indicates strabismus surgery is required.

Resection of medial rectus horizontal and lateral rectus muscles: Specific muscles addressed during the surgery.

Adjustable sutures: Used in securing the muscles, indicating specific techniques.

Extensive scar tissue from previous surgery: Requires additional work and isolation.

CPT codes 67314 and 67334 are used to report the resection of two muscles with adjustable sutures (67314) and surgery on an extraocular muscle involving extensive scar tissue (67334).

This scenario describes acytogenetic-type analysis targetingchromosomal abnormalities, performed using fluorescence-based microscopy techniques (commonly conceptually aligned with FISH-type evaluation). The question explicitly states thatno specific CPT code accurately describes the service, which signals that anunlistedcode is required. In CPT, the88299code is the unlisted procedure code forcytogenetic studies, used when a chromosomal/genetic laboratory procedure does not have a more specific existing CPT descriptor. The other unlisted options correspond to different laboratory sections:84999is an unlisted chemistry procedure,88199is an unlisted cytopathology procedure, and88749is not the correct unlisted cytogenetics code for this context as presented. CPC exam technique: match thedomainfirst (chromosomes → cytogenetics), then select the appropriateunlisted code within that domainwhen the stem says no specific CPT code exists. Proper use of unlisted codes also implies documentation of method, purpose, and comparables for payer review, but the test asks only for the correct unlisted CPT code.

69905 = Transmastoid labyrinthectomy

69990 = Operating microscope (separately reportable)

H81.391 = Peripheral vertigo, right ear

R42 (dizziness) is not reported when a definitive diagnosis exists

RADIOLOGY & IMAGING QUESTIONS

The correct answer is A. 72050. Modifier 26 is used to report the professional component of a service when the provider performs only the physician work portion, such as interpretation and report, and not the technical portion of the service. This modifier is commonly applicable to diagnostic services that may be divided into professional and technical components. Radiology services are the classic example because one entity may perform the imaging study using equipment and staff, while a physician separately interprets the images and issues the report. Medicare guidance also describes modifier 26 as appropriate when a physician interprets a test but does not perform the technical portion, especially for radiology services such as X-rays.

Code 72050 is a diagnostic radiology CPT® code for a cervical spine X-ray study, which supports a professional and technical component split. By contrast, 99283 is an emergency department E/M code, 90460 is immunization administration, and 93042 already represents interpretation/report work, so modifier 26 is not the best choice for those options.

Reference topics: CPC Modifiers; CPT Appendix A Modifier 26; Radiology Coding; Professional Component versus Technical Component.

Moderate sedation codes are selected by (1)patient ageand (2) whether the sedation is provided by thesame physician performing the procedureor by a different provider. The stem states theorthopedist provides the sedation and the reduction, so the sedation is provided by thesame physicianwho performs the procedure. For age, the patient is5 years old, which falls into the≥5 yearscategory. Therefore, the correct initial moderate sedation code is99152(moderate sedation provided by the same physician/other qualified provider performing the procedure; patient age 5 years or older; initial 15 minutes). The documented time is21 minutes, which supports only theinitialcode (it does not reach the threshold needed to report an additional 15-minute increment add-on). Code99151is for patientsunder 5 years, so it does not apply. Codes99155/99156are for sedation provided by adifferentprovider than the one performing the procedure. CPC exam tip: age cutoffs matter—exactly 5years old uses the “5 years or older” code set.

1. E/M Code Category Selection:

The patient is a 19-year-old seen by his primary care physician for an annual preventive exam. His last exam was four years ago, and he has no complaints, indicating a preventive rather than problem-focused visit.

CPT® Code 99385 is for a new patient preventive visit for ages 18-39. Since the patient’s last visit was four years ago, this qualifies him as a new patient by CPT® standards (a patient is considered new if they have not received any professional services from the physician within the past three years).

2. Rationale for Excluding Other Options:

Code 99395 is for an established patient preventive visit for ages 18-39, which does not apply here since the patient is considered new after four years.

Code 99394 is for a preventive visit for an established patient aged 12-17, which does not match the patient’s age.

Code 99384 is for a new patient preventive visit for ages 12-17, which also does not apply given the patient’s age of 19.

3. AAPC and CPT® Coding Guidelines:

According to CPT® guidelines, 99385 is appropriate for a new patient in the 18-39 age range for a preventive visit, especially when they have not seen the provider in over three years.

Therefore, the correct answer is A. 99385.
