Athscl unsp type bypass of the right leg w ulcer of thigh

This code signifies the presence of atherosclerosis affecting a bypass graft in the right leg, specifically when the type of bypass graft is not documented. A key feature is the development of an ulceration on the thigh, indicating a severe complication of the underlying atherosclerotic disease. This condition represents a failure or compromise of the revascularization procedure due to progressive plaque buildup within the graft.

Use this code when documentation clearly indicates atherosclerosis of a bypass graft in the right leg, with an associated ulcer on the thigh, and the specific type of bypass graft (e.g., femoropopliteal, aortofemoral) is not specified. This code is appropriate for patients presenting with ischemic ulcers on the thigh in the context of a previously placed right leg bypass graft. Supporting documentation would include operative reports detailing the bypass graft, vascular studies confirming atherosclerosis, and wound care notes describing the thigh ulcer.

• Always seek clarification from the provider if the specific type of bypass graft is not documented, as more specific codes exist.
• Ensure the ulceration is explicitly documented as being on the thigh, as other locations would require different codes.
• Code also any associated infections of the ulcer (e.g., L97.313 for non-pressure chronic ulcer of right thigh with bone exposure).
