Athscl nonbiol bypass of the extrm w intrmt claud, oth extrm

This code signifies the hardening and narrowing of a non-biological (synthetic) bypass graft located in an extremity, leading to symptoms of intermittent claudication. This condition indicates a failure or complication of a previous revascularization procedure using an artificial graft, resulting in pain and cramping in the affected limb during exercise.

Use this code when documentation specifies atherosclerosis affecting a synthetic bypass graft in an extremity other than the lower leg (e.g., upper extremity or thigh) and the patient experiences intermittent claudication. This code is appropriate for patients presenting with graft stenosis or occlusion due to atherosclerotic changes in a non-autogenous bypass.

• Ensure the documentation clearly specifies a non-biological (synthetic) graft and intermittent claudication.
• Verify the affected extremity is "other" than the lower leg; specific codes exist for lower leg involvement.
• Code also any associated complications or underlying conditions, such as peripheral artery disease (PAD).
