ICD-10 Code I70.368 – Atherosclerosis of unspecified type of bypass graft(s) of the extremities with gangrene, other extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.368 – Atherosclerosis of unspecified type of bypass graft(s) of the extremities with gangrene, other extremity
What it is
This code identifies atherosclerotic narrowing or blockage in an unspecified bypass graft in an extremity, with gangrene affecting the other extremity. Use it when documentation clearly links graft disease and gangrene.
Clinical signs
Clinical features may include poor limb perfusion, tissue necrosis, skin discoloration, and nonhealing wounds. Clinical features vary; refer to documentation for the affected extremity and graft type.
When to use this code
Use this code when the provider documents atherosclerosis in an unspecified bypass graft of an extremity and gangrene in the other extremity. It is appropriate when laterality and graft details are not specified beyond the coded description. Confirm that the record supports both the bypass graft disease and gangrene.
Do not use for
Do not use this code if gangrene is absent or if the bypass graft type is specified differently and a more exact code applies. Check documentation.
Coding tip
Verify the operative history and laterality carefully, because “unspecified” here still requires documentation of bypass graft atherosclerosis and gangrene.
