Athscl nonbiol bypass of the right leg w ulceration of ankle

This code signifies the presence of atherosclerosis affecting a synthetic (nonbiological) bypass graft located in the right leg, specifically complicated by ulceration on the ankle. This indicates a failure or deterioration of the artificial vascular conduit, leading to compromised blood flow and tissue breakdown in the distal extremity.

Apply this code when documentation clearly states atherosclerosis within a nonbiological bypass graft of the right leg, accompanied by an ankle ulcer. This typically occurs in patients with peripheral artery disease who have undergone bypass surgery with synthetic grafts and are now experiencing graft failure with ischemic ulceration.

• Ensure documentation specifies "nonbiological" or "synthetic" graft; otherwise, consider codes for biological grafts.
• Verify the laterality (right leg) and the specific complication (ulceration of ankle) are explicitly stated.
• Sequence this code first if it is the primary reason for the encounter, followed by codes for associated conditions like peripheral artery disease.
