ICD-10 Code I70.419 – Atherosclerosis of autologous vein bypass graft(s) of the extremities with intermittent claudication, unspecified extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.419 – Atherosclerosis of autologous vein bypass graft(s) of the extremities with intermittent claudication, unspecified extremity
What it is
This code describes plaque buildup in an autologous vein bypass graft in an arm or leg, causing intermittent claudication. Use it when the graft is the diseased vessel and the affected extremity is not specified.
Clinical signs
Typical findings include exertional leg or arm pain that improves with rest, consistent with intermittent claudication. Clinical features vary; refer to documentation for graft location, symptoms, and whether the extremity is specified.
When to use this code
Use this code when the provider documents atherosclerosis affecting an autologous vein bypass graft in an extremity and links it to intermittent claudication. It is appropriate when the record does not identify right or left extremity. Check documentation for the bypass type and symptom relationship.
Do not use for
Do not use this code for native artery atherosclerosis, graft occlusion without atherosclerosis, or claudication not documented as related to the bypass graft. Check documentation if the extremity or graft type is unclear.
Coding tip
Verify that the note names an autologous vein bypass graft and intermittent claudication before assigning I70.419.
