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

This code signifies a specific type of peripheral artery disease where atherosclerosis has developed within a bypass graft previously implanted in the left leg. The condition is complicated by the presence of an ulcer located on the heel or midfoot region of that same left leg. This indicates a severe manifestation of graft failure and tissue damage.

Use this code when documentation clearly states atherosclerosis affecting a bypass graft in the left leg, specifically noting an ulceration on the heel or midfoot. This typically applies to patients with a history of peripheral bypass surgery who are now presenting with graft stenosis or occlusion and associated tissue loss. Supporting documentation would include operative reports detailing the bypass, vascular studies confirming graft atherosclerosis, and wound care notes describing the heel/midfoot ulcer.

• Ensure the documentation specifies "atherosclerosis" of the graft, not just "occlusion" or "stenosis" without an atherosclerotic etiology.
• Verify the laterality (left leg) and the exact location of the ulceration (heel and midfoot) are explicitly stated.
• Always sequence this code after any underlying systemic conditions contributing to the atherosclerosis, if applicable, and consider additional codes for the specific type of ulcer if further detail is provided (e.g., pressure ulcer, diabetic ulcer).
