ICD-10 Code I70.32 – Atherosclerosis of unspecified type of bypass graft(s) of the extremities with rest pain (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.32 – Atherosclerosis of unspecified type of bypass graft(s) of the extremities with rest pain
What it is
This code identifies atherosclerotic narrowing in a bypass graft supplying an extremity, with ischemic pain present at rest. Use it when documentation names an unspecified bypass graft of the arm or leg and notes rest pain.
Clinical signs
Typical findings include persistent limb pain at rest, often worse when the leg is elevated and relieved by dependency. Clinical features vary; refer to documentation for the graft type, limb involved, and evidence of ischemia.
When to use this code
Use I70.32 when the provider documents atherosclerosis affecting an unspecified bypass graft in an extremity and specifically links it to rest pain. It is appropriate for follow-up visits, vascular evaluations, or problem lists that confirm this diagnosis. Check documentation if the graft type or symptom wording is unclear.
Do not use for
Do not use this code if the record describes claudication only, no rest pain, or a native artery lesion instead of a bypass graft. If the documentation does not specify atherosclerosis of a bypass graft, check documentation.
Coding tip
Assign the code only when both the bypass graft location and rest pain are documented together; otherwise, query for clarification.
