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

This code signifies a diagnosis of atherosclerosis affecting a bypass graft in the right leg, where the specific type of bypass graft is not documented. A key feature is the presence of an ulceration located on the ankle, indicating a complication of the atherosclerotic disease within the graft.

Apply this code when documentation clearly states atherosclerosis of a right leg bypass graft, the graft type is unspecified, and an ankle ulceration is present. This is typically seen in patients with peripheral artery disease who have undergone bypass surgery and subsequently developed graft failure with skin breakdown. Supporting documentation would include operative reports for the bypass, vascular studies confirming graft atherosclerosis, and wound care notes detailing the ankle ulcer.

• Ensure the documentation specifies "unspecified type" of bypass graft; otherwise, a more specific code for the graft type should be used.
• Verify the laterality (right leg) and the specific location of the ulceration (ankle).
• Consider additional codes for any associated conditions, such as diabetes mellitus with peripheral circulatory complications, if documented.
