ICD-10 Code I70.768 – Atherosclerosis of other type of bypass graft(s) of the extremities with gangrene, other extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.768 – Atherosclerosis of other type of bypass graft(s) of the extremities with gangrene, other extremity
What it is
This code identifies atherosclerotic narrowing or blockage in a bypass graft in an extremity, with gangrene present in the other extremity. Use it when the record clearly links the graft disease and gangrene to the documented site.
Clinical signs
Findings may include poor limb perfusion, tissue necrosis, blackened or dead tissue, and diminished pulses. Clinical features vary; refer to documentation for the affected limb and the bypass graft involvement.
When to use this code
Use I70.768 when the provider documents atherosclerosis affecting an “other type” bypass graft in an extremity and gangrene in the other extremity. The note should support both the graft location and the gangrenous site. If the laterality or site is unclear, check documentation before assigning the code.
Do not use for
Do not use this code for atherosclerosis without gangrene, or for native artery disease without bypass graft involvement. Do not assign it when the chart does not specify the other extremity or the graft type.
Coding tip
Verify the exact graft type, limb laterality, and gangrene location in the operative note or assessment before coding.
