ICD-10 Code I70.628 – Atherosclerosis of nonbiological bypass graft(s) of the extremities with rest pain, other extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.628 – Atherosclerosis of nonbiological bypass graft(s) of the extremities with rest pain, other extremity
What it is
This code identifies atherosclerotic narrowing in a nonbiological bypass graft in an extremity, with ischemic pain present at rest. It applies to the “other extremity” when the affected limb is not specified as right or left.
Clinical signs
Typical documentation includes peripheral arterial disease in a bypass graft plus rest pain, often worse when the limb is elevated or during the night. Clinical features vary; refer to documentation.
When to use this code
Use I70.628 when the provider documents atherosclerosis affecting a nonbiological bypass graft in an extremity and specifically notes rest pain. Choose this code when the record identifies the graft as synthetic or nonautologous and the limb is documented as other extremity. If laterality is missing, check documentation before coding.
Do not use for
Do not use this code for native artery atherosclerosis, acute graft occlusion, or bypass graft problems without documented atherosclerosis. Check documentation if the pain is exertional only or if the limb laterality is clearly stated elsewhere.
Coding tip
Verify both the graft type and the presence of rest pain before assigning I70.628.
