ICD-10 Code I70.721 – Atherosclerosis of other type of bypass graft(s) of the extremities with rest pain, right leg (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.721 – Atherosclerosis of other type of bypass graft(s) of the extremities with rest pain, right leg
What it is
This code identifies atherosclerotic narrowing or blockage in a bypass graft in the right leg, with rest pain present. It applies when the graft is of another specified type and the pain occurs without activity.
Clinical signs
Typical findings include ischemic pain in the right leg at rest, often worse when the limb is elevated. Clinical features vary; refer to documentation for graft type, laterality, and evidence of peripheral arterial disease.
When to use this code
Use this code when the record clearly states atherosclerosis affecting an extremity bypass graft in the right leg and documents rest pain. It is appropriate for postoperative vascular follow-up or evaluation of graft-related ischemia. Check documentation if the graft type is not specified.
Do not use for
Do not use this code for native artery disease without a bypass graft, or for pain that is not documented as rest pain. Do not assign it if the laterality is left or unspecified.
Coding tip
Verify the graft location, graft type, laterality, and the exact phrase “rest pain” before assigning I70.721.
