Athscl nonbiol bypass of left leg w ulcer of heel and midft

This code signifies a specific type of peripheral artery disease where a non-biological (e.g., synthetic) bypass graft in the left leg has developed atherosclerosis, leading to compromised blood flow. This vascular insufficiency has progressed to cause ulceration on the heel and midfoot regions of the same leg.

Use this code when documentation clearly indicates atherosclerosis affecting a synthetic bypass graft in the left lower extremity, accompanied by open sores or wounds on the heel and/or midfoot. This typically occurs in patients with a history of peripheral bypass surgery who are now presenting with ischemic ulcerations.

• Confirm the laterality (left leg) and the specific location of the ulceration (heel and midfoot).
• Ensure the graft is explicitly documented as "nonbiological" or "synthetic" to differentiate from autologous grafts.
• Look for documentation of the underlying atherosclerosis of the graft as the cause of the ulceration.
