CPC Leak Questions

00813 = Anesthesia for colonoscopy

QK = Medical direction of 2–4 cases

99100 = Extreme age

99140 = Emergency anesthesia

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.

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.

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.
