ICD-10 Code I70.65 – Atherosclerosis of nonbiological bypass graft(s) of other extremity with ulceration (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.65 – Atherosclerosis of nonbiological bypass graft(s) of other extremity with ulceration
What it is
This code identifies atherosclerotic narrowing or blockage in a nonbiological bypass graft supplying an extremity, with associated ulceration. Use it when the graft disease and the ulcer are both documented.
Clinical signs
Clinical features vary; refer to documentation. Findings may include impaired limb perfusion, diminished pulses, ischemic pain, and a documented ulcer in the affected extremity or graft territory.
When to use this code
Use I70.65 when the provider documents atherosclerosis affecting a nonbiological bypass graft in an extremity and specifically links ulceration to that condition. It is appropriate when the ulcer is part of the coded diagnosis, not merely a separate wound note. Check documentation for laterality and the exact graft site.
Do not use for
Do not use this code for native-vessel peripheral arterial disease without a bypass graft, or for ulcers without documented atherosclerosis of the graft. If the graft type or ulcer relationship is unclear, check documentation.
Coding tip
Confirm that the ulcer is documented as associated with the graft atherosclerosis before assigning I70.65.
