Oth athscl type of bypass of the extremities, right leg

This code describes the presence of atherosclerosis affecting a bypass graft located in the right leg, where the specific type of atherosclerosis is not further specified as native artery, autologous vein, or nonautologous biological. This indicates a hardening and narrowing of the graft due to plaque buildup, impairing blood flow to the distal extremity.

Use this code when documentation clearly indicates atherosclerosis within a bypass graft in the right lower extremity, and the type of graft (e.g., saphenous vein, synthetic) or the specific type of atherosclerosis (e.g., native artery, autologous vein, nonautologous biological) is not specified. This code is appropriate for patients presenting with symptoms of peripheral artery disease (PAD) or graft failure due to atherosclerosis in a right leg bypass.

• Ensure the documentation specifies "other" atherosclerosis and "other type of bypass graft" to justify this specific code.
• Always specify the laterality (right leg) as indicated in the code.
• Sequence this code as a secondary diagnosis when the primary reason for the encounter is a complication directly related to the atherosclerosis, such as claudication or rest pain.
