ICD-10 Code I70.444 – Atherosclerosis of autologous vein bypass graft(s) of the left leg with ulceration of heel and midfoot (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.444 – Atherosclerosis of autologous vein bypass graft(s) of the left leg with ulceration of heel and midfoot
What it is
This code identifies atherosclerotic narrowing or blockage in an autologous vein bypass graft in the left leg, with an associated ulcer on the heel and midfoot. Use it when the documentation links the graft disease to that specific ulcer location.
Clinical signs
Typical findings include impaired circulation in the bypass graft and a documented ulcer involving the heel and midfoot. Clinical features vary; refer to documentation for laterality, graft type, and ulcer site.
When to use this code
Use this code when the provider documents atherosclerosis affecting an autologous vein bypass graft in the left leg and specifies ulceration of the heel and midfoot. It is appropriate when the ulcer location is clearly stated and tied to the vascular disease. Check documentation if the graft type or ulcer site is unclear.
Do not use for
Do not use this code for native artery atherosclerosis without a bypass graft, or for ulcers not documented in the heel and midfoot. Check documentation if the ulcer is on another site or the graft is not autologous vein.
Coding tip
Verify both the graft type and the exact ulcer location before assigning I70.444.
