ICD-10 Code I70.435 – Atherosclerosis of autologous vein bypass graft(s) of the right leg with ulceration of other part of foot (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.435 – Atherosclerosis of autologous vein bypass graft(s) of the right leg with ulceration of other part of foot
What it is
This code identifies atherosclerotic narrowing in an autologous vein bypass graft in the right leg, with an associated ulcer on another part of the foot. Use it when the record links the graft disease and the ulcer.
Clinical signs
Findings may include reduced graft perfusion, limb ischemic symptoms, and a documented foot ulcer. Clinical features vary; refer to documentation, especially for graft location, laterality, and ulcer site.
When to use this code
Use I70.435 when the provider documents atherosclerosis affecting an autologous vein bypass graft in the right leg and specifies ulceration of another part of the foot. The ulcer must be clinically tied to the same vascular condition. Check documentation if the graft type, side, or ulcer location is unclear.
Do not use for
Do not use this code for ulcers without documented atherosclerotic graft disease, or for disease in a native artery or a different bypass graft type. Do not assume the right leg if laterality is not stated.
Coding tip
Verify all three elements: autologous vein graft, right leg, and ulceration of other part of foot.
