A diagnostic mammogram performed on both breasts with computer-aided detection (CAD) is reported with CPT® code 77066. This code is used when CAD is utilized to further analyze the images for possible lesions, and it covers both breasts.

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.

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.
