ICD-10 Code I70.534 – Atherosclerosis of nonautologous biological bypass graft(s) of the right leg with ulceration of heel and midfoot (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.534 – Atherosclerosis of nonautologous biological bypass graft(s) of the right leg with ulceration of heel and midfoot
What it is
This code identifies atherosclerotic narrowing or blockage in a nonautologous biological bypass graft in the right leg, with an associated ulcer on the heel or midfoot. It combines the vascular graft problem and the ulcer location in one diagnosis.
Clinical signs
Typical findings include reduced blood flow in the graft, limb ischemia, and a documented ulcer on the right heel or midfoot. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents atherosclerosis affecting a nonautologous biological bypass graft in the right leg and specifies ulceration of the heel or midfoot. The ulcer must be linked to the documented vascular disease. Check documentation if laterality, graft type, or ulcer site is unclear.
Do not use for
Do not use it for native artery atherosclerosis, unrelated ulcers, or bypass graft disease without ulceration. If the graft type or ulcer location is not documented, check documentation.
Coding tip
Verify both the graft type and the exact ulcer site before assigning I70.534.
