ICD-10 Code I70.418 – Atherosclerosis of autologous vein bypass graft(s) of the extremities with intermittent claudication, other extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.418 – Atherosclerosis of autologous vein bypass graft(s) of the extremities with intermittent claudication, other extremity
What it is
This code identifies atherosclerotic narrowing in an autologous vein bypass graft in an extremity, with intermittent claudication affecting the other extremity. Use it when the graft is the documented site and the claudication is part of the diagnosis.
Clinical signs
Typical findings include exertional leg pain that improves with rest, along with evidence of peripheral arterial disease in a bypass graft. Clinical features vary; refer to documentation.
When to use this code
Use I70.418 when the provider documents atherosclerosis in an autologous vein bypass graft of an extremity and specifies intermittent claudication in the other extremity. Confirm that the graft is autologous vein, not prosthetic or unspecified. If laterality or the affected extremity is unclear, check documentation.
Do not use for
Do not use this code for native artery atherosclerosis without a bypass graft, or for prosthetic graft disease. Do not use it when claudication is absent or when the documentation does not support the specified extremity.
Coding tip
Verify graft type, affected extremity, and the presence of intermittent claudication before assigning I70.418.
