ICD-10 Code I70.568 – Atherosclerosis of nonautologous biological bypass graft(s) of the extremities with gangrene, other extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.568 – Atherosclerosis of nonautologous biological bypass graft(s) of the extremities with gangrene, other extremity
What it is
This code identifies atherosclerotic disease affecting a nonautologous biological bypass graft in an extremity, with gangrene present in the other specified limb. Use it when documentation links the graft disease and gangrene to the same clinical picture.
Clinical signs
Findings may include poor limb perfusion, tissue necrosis, blackened or nonviable skin, and loss of distal circulation in the affected extremity. Clinical features vary; refer to documentation.
When to use this code
Use I70.568 when the provider documents atherosclerosis involving a nonautologous biological bypass graft in an extremity and gangrene in the other extremity specified by the record. Confirm the graft type, laterality, and gangrene location before assigning the code.
Do not use for
Do not use this code if gangrene is absent, if the bypass graft is autologous or synthetic, or if the documentation does not support atherosclerotic graft disease. Check documentation.
Coding tip
Verify the graft material and the exact extremity involved, because laterality and graft type determine whether I70.568 is appropriate.
