ICD-10 Code I70.762 – Atherosclerosis of other type of bypass graft(s) of the extremities with gangrene, left leg (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.762 – Atherosclerosis of other type of bypass graft(s) of the extremities with gangrene, left leg
What it is
This code identifies atherosclerotic narrowing or blockage in a bypass graft in the left leg, with gangrene present. Use it when the graft, not the native artery alone, is the documented site of disease.
Clinical signs
Findings may include ischemic pain, coolness, poor wound healing, skin color change, and necrotic tissue in the left leg. Clinical features vary; refer to documentation for the graft type and evidence of gangrene.
When to use this code
Use this code when the provider documents atherosclerosis affecting an “other type” bypass graft in the left lower extremity and gangrene is present. The record should clearly link the disease to the graft and specify the left leg. If the note only mentions peripheral arterial disease or graft occlusion without gangrene, check documentation before coding.
Do not use for
Do not use it for native vessel atherosclerosis, graft disease without gangrene, or gangrene without documented atherosclerotic graft involvement. Check documentation if the bypass graft type or laterality is unclear.
Coding tip
Confirm both the graft location and the gangrene documentation before assigning I70.762.
