ICD-10 Code I70.729 – Atherosclerosis of other type of bypass graft(s) of the extremities with rest pain, unspecified extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.729 – Atherosclerosis of other type of bypass graft(s) of the extremities with rest pain, unspecified extremity
What it is
This code identifies plaque buildup in a bypass graft supplying an extremity, with ischemic rest pain. It is used when the graft type is not otherwise specified and the affected limb is not documented.
Clinical signs
Typical findings include pain in the foot or leg at rest, often worse when the limb is elevated and relieved by dependency. Clinical features vary; refer to documentation for evidence of graft-related peripheral arterial disease.
When to use this code
Use this code when the record documents atherosclerosis affecting an extremity bypass graft and the patient has rest pain. Choose it when the provider does not specify the limb or the graft is described as another type. Confirm that the pain is ischemic and related to the graft.
Do not use for
Do not use this code for native artery atherosclerosis without a bypass graft, or for claudication only. Check documentation if the pain is due to another cause or if the extremity is specified elsewhere.
Coding tip
Verify both the bypass graft involvement and rest pain in the note before assigning I70.729.
