ICD-10 Code I70.744 – Atherosclerosis of other type of bypass graft(s) of the left leg with ulceration of heel and midfoot (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.744 – Atherosclerosis of other type of bypass graft(s) of the left leg with ulceration of heel and midfoot
What it is
This code identifies atherosclerotic narrowing in a nonautologous bypass graft in the left leg, with an associated ulcer on the heel and midfoot. Use it when documentation links the graft disease to that specific ulcer location.
Clinical signs
Typical findings include reduced leg perfusion, graft-related ischemic symptoms, and a documented ulcer involving the heel or midfoot. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record states atherosclerosis affects an other-type bypass graft in the left leg and the same encounter documents ulceration of the heel and midfoot. You should verify laterality, graft type, and ulcer site in the note. If the ulcer location is not specified, check documentation.
Do not use for
Do not use this code for native artery disease, bypass graft disease in the right leg, or ulcers at other sites without heel and midfoot involvement. Check documentation.
Coding tip
Confirm that the ulcer is linked to the graft disease and that the graft is not autologous before assigning I70.744.
