Athscl autol vein bypass of extrm w intrmt claud, right leg

This code signifies a diagnosis of peripheral artery disease (PAD) specifically affecting an autologous vein bypass graft in the right leg. The atherosclerosis within the graft is causing symptoms of intermittent claudication, indicating compromised blood flow during exertion.

Use this code when documentation clearly states atherosclerosis of an autologous vein bypass graft in the right lower extremity, accompanied by symptoms of intermittent claudication. This typically applies to patients who have undergone prior bypass surgery using their own vein and are now experiencing graft failure due to atherosclerotic changes.

• Ensure the documentation specifies "autologous vein" and not another type of graft (e.g., synthetic).
• Verify that the laterality is explicitly stated as "right leg" and that intermittent claudication is present.
• Do not use this code if the atherosclerosis is in a native artery or a non-autologous graft.
