Athscl type of bypass of the right leg w ulceration of thigh

This code signifies a specific type of peripheral artery disease where atherosclerosis has developed within a bypass graft located in the right leg. The condition is further complicated by the presence of an ulcer on the patient's thigh, indicating severe tissue damage due to compromised blood flow. This represents a failure or complication of a previous revascularization procedure.

Utilize this code when documentation clearly states atherosclerosis affecting a bypass graft in the right leg, specifically with an ulcerated lesion on the thigh. This typically applies to patients presenting with chronic limb ischemia symptoms, non-healing wounds, or graft surveillance findings indicating stenosis or occlusion. Supporting documentation should include imaging reports (e.g., duplex ultrasound, angiography) confirming graft atherosclerosis and physical exam findings describing the thigh ulcer.

• Ensure the documentation specifies "other type of bypass graft(s)" and not an autologous vein or nonautologous biological bypass graft, which have distinct codes.
• Verify the laterality is explicitly stated as the "right leg" and the ulceration is specifically located on the "thigh."
• Sequence this code as the primary diagnosis when the atherosclerosis and ulceration are the reason for the encounter, followed by codes for any associated conditions or complications.
