ICD-10 Code I70.361 – Atherosclerosis of unspecified type of bypass graft(s) of the extremities with gangrene, right leg (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.361 – Atherosclerosis of unspecified type of bypass graft(s) of the extremities with gangrene, right leg
What it is
This code identifies atherosclerosis affecting an unspecified bypass graft in the extremities, with gangrene present in the right leg. It indicates severe arterial disease in a graft supplying limb blood flow.
Clinical signs
Expect documentation of peripheral arterial disease in a bypass graft plus gangrene of the right lower extremity. Clinical features vary; refer to documentation for tissue necrosis, ischemic discoloration, or loss of viable tissue.
When to use this code
Use this code when the provider documents atherosclerosis in a bypass graft of an extremity and specifically states gangrene in the right leg. It applies when the graft type is not further specified. Check documentation if the record does not clearly link the gangrene to the right leg.
Do not use for
Do not use it for native artery atherosclerosis, bypass graft disease without gangrene, or gangrene in a different limb. Check documentation if the graft site or laterality is unclear.
Coding tip
Verify both the bypass graft involvement and the right-leg gangrene before assigning I70.361.
