Athscl type of bypass of the extrm w intrmt claud, right leg

This code signifies the presence of atherosclerosis affecting a previously implanted bypass graft in the right leg, leading to symptoms of intermittent claudication. This condition indicates a narrowing or hardening of the graft, impairing blood flow to the extremity, particularly during exertion.

Use this code when documentation confirms atherosclerotic changes within a bypass graft in the right lower extremity, and the patient experiences pain, cramping, or weakness in the leg that is relieved by rest. Supporting documentation should include imaging reports (e.g., angiography, duplex ultrasound) demonstrating graft stenosis or occlusion due to atherosclerosis, along with a physician's assessment of intermittent claudication.

• Ensure the documentation clearly specifies "other type" of bypass graft, as distinct codes exist for autologous vein and nonautologous biological bypass grafts.
• Verify laterality (right leg) is explicitly stated in the medical record.
• Do not use this code if the claudication is due to native vessel atherosclerosis without graft involvement, or if the graft is in an upper extremity.
