Athscl nonbiol bypass of the right leg w ulcer oth prt foot

This code describes a specific type of peripheral artery disease involving the hardening and narrowing of a non-biological (synthetic) bypass graft located in the right leg. The atherosclerosis has progressed to cause ulceration on a part of the foot, indicating severe tissue damage due to compromised blood flow.

This code is used when documentation clearly identifies atherosclerosis affecting a synthetic bypass graft in the right leg, specifically with an associated ulcer on the foot. It applies to patients with a history of lower extremity revascularization using a non-biological graft who subsequently develop graft stenosis and foot ulceration. Supporting documentation would include operative reports detailing the graft type and location, vascular studies confirming graft atherosclerosis, and wound care notes describing the foot ulcer.

• Ensure the documentation specifies a non-biological bypass graft; biological grafts would be coded differently.
• Verify the laterality (right leg) and the presence of ulceration on the foot.
• Always code the underlying atherosclerosis first, followed by codes for any associated complications like gangrene or rest pain, if present.
