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

This code signifies the presence of atherosclerosis affecting a synthetic or non-biological bypass graft in the left leg, complicated by ulceration. This condition indicates a narrowing or hardening of the graft due to plaque buildup, leading to impaired blood flow and tissue breakdown in the left lower extremity.

Use this code when documentation explicitly states atherosclerosis of a non-biological bypass graft in the left leg, along with the presence of an ulcer. This typically applies to patients with a history of peripheral artery disease who have undergone bypass surgery using a synthetic graft and are now experiencing graft failure with associated tissue loss.

• Ensure the documentation specifies "nonbiological" or "synthetic" graft; otherwise, a different code for biological grafts may be appropriate.
• Confirm the laterality is "left leg" and that an ulceration is present.
• This code requires an additional code to specify the type of ulcer (e.g., pressure ulcer, chronic ulcer of lower limb).
