ICD-10 Code I70.62 – Atherosclerosis of nonbiological bypass graft(s) of the extremities with rest pain (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.62 – Atherosclerosis of nonbiological bypass graft(s) of the extremities with rest pain
What it is
This code identifies atherosclerotic narrowing in a nonbiological bypass graft in an arm or leg, with pain present at rest. It reflects impaired blood flow through the graft rather than disease in a native artery.
Clinical signs
Typical findings include ischemic rest pain, often worse when the limb is elevated and relieved by dependency. Clinical features vary; refer to documentation for graft type, limb location, and evidence of atherosclerotic disease.
When to use this code
Use this code when the provider documents atherosclerosis affecting a synthetic or other nonbiologic bypass graft in an extremity and specifically notes rest pain. It may apply after prior bypass surgery when the graft becomes narrowed by plaque. Confirm that the pain is attributed to the graft disease and not another cause.
Do not use for
Do not use this code for atherosclerosis of native arteries, graft occlusion without documented atherosclerosis, or pain from nonvascular causes. Check documentation if the graft material or symptom pattern is unclear.
Coding tip
Code only when both the nonbiological graft and rest pain are documented together; otherwise, verify the exact vascular site and diagnosis wording.
