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

This code signifies a condition where a synthetic (nonbiological) bypass graft in the right leg has developed atherosclerosis, leading to impaired blood flow. This arterial hardening has resulted in open sores or wounds specifically located on the heel and midfoot regions of the same leg.

Apply this code when documentation explicitly states atherosclerosis affecting a nonbiological bypass graft in the right lower extremity, accompanied by ulceration of the heel and midfoot. This typically occurs in patients with a history of peripheral artery disease who have undergone bypass surgery using synthetic materials.

• Ensure documentation specifies "nonbiological" graft material; biological grafts would use a different code series.
• Verify the laterality (right leg) and the specific ulceration sites (heel and midfoot) are clearly documented.
• 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.
