Athscl nonaut bio bypass of r leg w ulcer of heel and midft

This code signifies the hardening and narrowing of a non-native biological bypass graft located in the right leg, specifically complicated by open sores on the heel and midfoot. This condition impairs blood flow through the graft, leading to tissue damage and ulcer formation in the distal extremity. It represents a specific type of peripheral artery disease affecting a previously implanted bypass.

Apply this code when documentation clearly indicates atherosclerosis affecting a non-autologous (e.g., bovine, synthetic) bypass graft in the right lower limb, with co-occurring ulceration of the heel and/or midfoot. This is typically seen in patients with a history of peripheral revascularization who are now experiencing graft failure and ischemic tissue loss. Supporting documentation should specify the graft type, location, and the presence and location of the ulcers.

• Ensure the documentation specifies "nonautologous biological" graft; do not use for autologous grafts or other graft types.
• Verify the laterality is explicitly "right leg" and that ulceration is present on the "heel and midfoot."
• Consider sequencing this code after any underlying systemic conditions contributing to atherosclerosis, if applicable.
