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

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.

Thelunulais the pale, crescent-shaped area visible at the base of some fingernails and toenails (most commonly the thumb). It is part of thenail unit, associated with the nail matrix where nail formation occurs. Because the lunula is anail structure, a biopsy “of the lunula” is anail biopsy, even though a punch tool is also commonly used in skin biopsies. CPC exam questions frequently test precise anatomical vocabulary, especially for integumentary structures (skin, nail, hair). The distractors “eye” and “brain” are unrelated, and “skin” is tempting because punch biopsies are typically skin procedures; however, the question specifically identifies thelunula, which is not a skin landmark. Coding and documentation accuracy depend on knowing these terms because nail procedures often have different code families and clinical considerations than routine skin biopsies. Correct identification starts by mapping the term to its anatomical system: lunula → nail apparatus.

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.

NCCIstands for theNational Correct Coding Initiative. Its purpose is to promote correct coding by identifying code pairs that shouldnotbe reported together in most circumstances, helping preventunbundlingand improper payment. The NCCI includesProcedure-to-Procedure (PTP) editsand guidance that reflect common clinical coding conventions (for example, when one service is considered integral to another). Importantly, NCCI edits do not “eliminate the need for modifiers”; rather, they clarify when a modifier (such as-59or an appropriate X{EPSU} modifier) may be allowedonly whendocumentation supports that the services were truly distinct (different site, session, lesion, or other qualifying circumstance). Options A and C incorrectly name the initiative and misstate its function, and option B is not the correct expansion or purpose. For CPC exam readiness, understand NCCI as a primary Medicare edit set widely used as a reference by many payers, supporting consistent and accurate reporting and reducing payment errors.

CPT70450describes aCT of the head/brain without contrast. When aradiology facilityperforms the technical portion (scanner, technologist, supplies) and theprovider only interprets and reportsthe study, the provider bills theprofessional componentusing modifier-26. That is exactly what the vignette describes: the radiology facility performed the scan, and the provider received images and provided the interpretation—so the provider reports70450-26. Reporting70450alone would imply billing the global service (professional + technical), which would be incorrect because the provider did not supply the equipment/technical resources. Modifier-TCis used to bill thetechnical component, which would be reported by the facility, not the interpreting provider in this scenario. Modifier-26-TCtogether is not appropriate because it would contradict itself (professional and technical simultaneously). CPC exam tip: always determinewho performedthe technical work andwho interpreted; then use-26for interpretation-only billing.

36223 = Selective catheterization of common carotid with imaging

36227 ×2 = Bilateral external carotid angiography

The correct CPT® code for a therapeutic drug test to monitor the total level of carbamazepine is 80156. The ICD-10-CM code G40.909 is used for epileptic seizures, not otherwise specified, which aligns with the patient ' s condition being treated for seizures.

This patient presents to the ER with syncope, requiring a comprehensive evaluation and critical care. Here ' s the breakdown of the codes:

CPT Code 99291-25: Critical care, evaluation and management of the critically ill or critically injured patient; first 30-74 minutes  

This code is appropriate because the patient ' s syncope and vital signs (low blood pressure, shallow respirations, low oxygen saturation) indicate a critical condition requiring immediate intervention.

Modifier -25: Significant, Separately Identifiable Evaluation and Management Service by the Same Physician on the Same Day of the Procedure or Other Service. This modifier is appended because the critical care services were provided in addition to the separately reported procedures below.  

CPT Code 92950: Cardiopulmonary resuscitation (eg, CPR, external cardiac massage, endotracheal intubation, ventilation)

While the documentation doesn ' t explicitly mention CPR, it states the patient was unresponsive upon arrival but had spontaneous pulse and respirations. This suggests possible resuscitation efforts were performed by the paramedics before the physician ' s assessment.

CPT Code 31500: Intubation, endotracheal, emergency procedure

Although not explicitly stated, the documentation indicates the patient was placed on " high flow oxygen, " which strongly suggests endotracheal intubation was performed to manage the patient ' s respiratory distress.

CPT Code 82803: Blood gases, arterial, pH, PCO2, PO2, with oxygen saturation; interpretation and report

This code is likely reported based on the patient ' s respiratory distress and the need to monitor their oxygenation status.

Why other options are incorrect:

99285: This is a standard emergency department visit code and doesn ' t capture the critical nature of the patient ' s condition.

99285-25, 99291-25, 92950, 31500, 82803: This includes 99285, which is not necessary as 99291 encompasses the evaluation and management.

99291-25, 99292-25, 92950, 31500: This includes 99292, which is for subsequent critical care time. There ' s no indication in the documentation that the physician provided critical care beyond the initial 74 minutes.

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
