ICD-10 Code I70.76 – Atherosclerosis of other type of bypass graft(s) of the extremities with gangrene (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.76 – Atherosclerosis of other type of bypass graft(s) of the extremities with gangrene
What it is
This code identifies atherosclerosis affecting a non-coronary bypass graft in an extremity when gangrene is present. It reflects severe loss of blood flow through the graft, with tissue death in the limb.
Clinical signs
Findings may include ischemic pain, cool or pale skin, weak pulses, and black or necrotic tissue in the affected area. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record documents atherosclerosis in an “other type” bypass graft of an arm or leg and gangrene is present. The diagnosis should link the graft disease to the gangrenous extremity findings. Check documentation if the graft type or site is unclear.
Do not use for
Do not use this code for native artery atherosclerosis without bypass graft involvement, or for graft disease without gangrene. If the chart does not specify gangrene, choose the more appropriate non-gangrenous code.
Coding tip
Verify the graft type, extremity site, and presence of gangrene before assigning I70.76.
