Athscl nonaut bio bypass of extrm w intrmt claud, left leg

This code signifies the hardening and narrowing of a biological bypass graft, not originating from the patient's own body, located in the left leg. This atherosclerotic process is causing intermittent claudication, characterized by pain or cramping in the leg during exercise that is relieved by rest. It indicates a complication of a previous revascularization procedure in the left lower extremity.

Use this code when documentation specifies atherosclerosis affecting a non-autologous (e.g., bovine, synthetic) bypass graft in the left leg, and the patient presents with symptoms of intermittent claudication. This code is appropriate for patients experiencing graft failure or compromise due to atherosclerotic changes in the implanted bypass conduit.

• Ensure documentation clearly specifies "nonautologous biological bypass graft" and "left leg" to support this specific code.
• Distinguish from atherosclerosis of native arteries or autologous grafts, which have different code assignments.
• Code any associated complications, such as ulceration or gangrene, as secondary diagnoses.
