ICD-10 Code I70.769 – Atherosclerosis of other type of bypass graft(s) of the extremities with gangrene, unspecified extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.769 – Atherosclerosis of other type of bypass graft(s) of the extremities with gangrene, unspecified extremity
What it is
This code identifies atherosclerotic disease in a bypass graft supplying an extremity, with gangrene present. Use it when the graft type is “other” and the affected limb is not specified.
Clinical signs
Findings may include poor limb perfusion, tissue death, black or necrotic skin, and ischemic pain. Clinical features vary; refer to documentation for the graft type, gangrene, and limb laterality.
When to use this code
Use I70.769 when documentation states atherosclerosis affects an extremity bypass graft and gangrene is present, but the extremity is unspecified. This is appropriate for postoperative or vascular follow-up notes that clearly identify the graft as the diseased vessel. Check documentation if the record names a different graft type or does not confirm gangrene.
Do not use for
Do not use this code for native artery atherosclerosis, graft occlusion without atherosclerosis, or gangrene without documented graft disease. Do not assign it if the affected extremity is specified and a more precise code is available.
Coding tip
Verify both the graft description and the presence of gangrene before coding, and capture laterality when the record supports it.
