ICD-10 Code I70.445 – Atherosclerosis of autologous vein bypass graft(s) of the left leg with ulceration of other part of foot (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.445 – Atherosclerosis of autologous vein bypass graft(s) of the left leg with ulceration of other part of foot
What it is
This code identifies atherosclerotic narrowing or blockage in an autologous vein bypass graft in the left leg, with an ulcer on another part of the foot. Use it when documentation links the graft disease and the ulceration.
Clinical signs
Typical findings include evidence of peripheral arterial disease affecting a vein graft, plus a documented foot ulcer. Clinical features vary; refer to documentation for laterality, graft type, and ulcer location.
When to use this code
Use this code when the provider documents atherosclerosis in an autologous vein bypass graft of the left leg and also specifies ulceration of another part of the foot. The ulcer must be associated with the coded vascular condition. Check documentation if the graft type or ulcer site is unclear.
Do not use for
Do not use it for native-vessel peripheral arterial disease without a bypass graft, or for ulcers not linked to the documented atherosclerosis. Do not assume laterality or graft material; check documentation.
Coding tip
Confirm the bypass graft is autologous vein, the affected leg is left, and the ulcer site is “other part of foot” before assigning I70.445.
