ICD-10 Code I70.761 – Atherosclerosis of other type of bypass graft(s) of the extremities with gangrene, right leg (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.761 – Atherosclerosis of other type of bypass graft(s) of the extremities with gangrene, right leg
What it is
This code identifies atherosclerotic disease in a bypass graft supplying the right leg, with gangrene present. Use it when documentation shows graft-related arterial narrowing or blockage and tissue death in the right lower extremity.
Clinical signs
Findings may include a cold, painful, or poorly perfused right leg, absent or diminished pulses, and black or necrotic tissue. Clinical features vary; refer to documentation.
When to use this code
Use I70.761 when the record specifically documents atherosclerosis affecting an “other type” bypass graft in the extremities and gangrene in the right leg. The diagnosis should link the vascular graft disease to the gangrenous limb. If the side, graft type, or gangrene is not clearly documented, check documentation.
Do not use for
Do not use this code for native-artery atherosclerosis without a bypass graft, or for gangrene without documented graft involvement. If the graft type or laterality differs, choose the more specific documented code.
Coding tip
Confirm both the graft location and the right-leg gangrene in the note before assigning I70.761.
