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.

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.

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.
