Athscl nonbiol bypass of the right leg w ulceration of thigh

This code describes the presence of atherosclerosis, a hardening and narrowing of arteries due to plaque buildup, specifically affecting a non-biological (synthetic) bypass graft located in the right leg. A key feature is the development of an ulceration on the patient's thigh, indicating a severe complication of the underlying vascular disease and graft failure.

This code is appropriate when documentation confirms atherosclerosis impacting a synthetic bypass graft in the right lower extremity, accompanied by an open sore or lesion on the thigh. Supporting documentation should clearly specify the laterality (right leg), the type of graft (non-biological), and the presence and location of the ulceration.

• Ensure the documentation specifies "nonbiological" or "synthetic" graft; biological grafts (e.g., saphenous vein) have different codes.
• Verify the laterality is explicitly stated as "right leg."
• Confirm the ulceration is located on the "thigh" as specified; ulcerations on other parts of the leg would require a different code.
