Athscl unsp type bypass of r leg w ulcer of heel and midft

This code signifies a specific type of peripheral artery disease where a previously placed bypass graft in the right leg has developed atherosclerosis, leading to ulceration on the heel and/or midfoot. The type of bypass graft is not specified in the documentation. This indicates a severe manifestation of graft failure with tissue loss.

Use this code when documentation clearly states atherosclerosis of a right leg bypass graft (of unspecified type) and specifically mentions ulceration of the heel and/or midfoot. This code is appropriate for patients presenting with chronic limb ischemia and tissue breakdown secondary to graft disease. Supporting documentation would include operative reports detailing the bypass, vascular studies confirming graft stenosis/occlusion, and wound care notes describing the ulcer.

• Ensure the documentation specifies "unspecified type" of bypass graft; otherwise, a more specific code for the graft type should be used.
• Verify the laterality (right leg) and the specific location of the ulceration (heel and/or midfoot).
• This code inherently includes both the atherosclerosis and the ulceration; do not code these conditions separately.
