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

This code signifies the hardening and narrowing of a synthetic (nonbiological) bypass graft located in the right leg, leading to symptomatic intermittent claudication. This condition indicates compromised blood flow through the graft, causing pain and cramping in the leg during exercise that is relieved by rest.

Use this code when documentation confirms atherosclerosis affecting a nonbiological bypass graft in the right lower extremity, and the patient experiences intermittent claudication as a direct result. This typically applies to patients with a history of peripheral artery disease who have undergone bypass surgery using a synthetic graft. Documentation should specify the graft type, location, and the presence of claudication.

• Ensure documentation explicitly states "nonbiological" or "synthetic" graft material.
• Verify the laterality (right leg) and the presence of intermittent claudication; do not use for asymptomatic atherosclerosis or other symptoms.
• Consider sequencing this code after a more specific code for the underlying peripheral artery disease if still active and contributing.
