Athscl nonbiol bypass of the left leg w ulceration of thigh

This code signifies the hardening and narrowing of a synthetic bypass graft in the left leg, specifically in the thigh region, which has led to the development of an open wound or sore. This condition is a complication of a previous vascular bypass surgery, where the artificial graft itself has become diseased.

Use this code when documentation confirms atherosclerosis affecting a nonbiological (e.g., Dacron, PTFE) bypass graft in the left leg, and there is a documented ulceration located on the thigh. This typically occurs in patients with a history of peripheral artery disease who have undergone revascularization with an artificial graft.

• Ensure the documentation specifies a nonbiological graft and the left leg.
• Confirm the ulceration is located on the thigh and is a direct result of the graft atherosclerosis.
• Sequence this code as a primary diagnosis when the atherosclerosis and ulceration are the focus of treatment, or as a secondary diagnosis if another condition is the primary reason for the encounter.
