Athscl nonbiol bypass of the right leg w ulcer of unsp site

This code describes the presence of atherosclerosis, a hardening and narrowing of arteries due to plaque buildup, specifically affecting a nonbiological (synthetic) bypass graft located in the right leg. The condition is complicated by ulceration, an open sore, at an unspecified location on the leg. This indicates a significant and symptomatic vascular compromise in the grafted vessel.

Use this code when documentation confirms atherosclerosis within a synthetic bypass graft of the right leg, accompanied by an ulcer. This typically applies to patients with a history of peripheral artery disease who have undergone bypass surgery using a prosthetic graft. The medical record must clearly state the presence of an ulcer and specify the right leg and nonbiological graft.

• Ensure the documentation explicitly states "nonbiological" or "synthetic" graft; otherwise, a different code for biological grafts would be appropriate.
• Verify the laterality (right leg) is clearly documented. If the leg is not specified, an unspecified laterality code should be used.
• This code requires an additional code to specify the exact site of the ulceration if known, as this code indicates an "unspecified site."
