ICD-10 Code I70.734 – Atherosclerosis of other type of bypass graft(s) of the right leg with ulceration of heel and midfoot (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.734 – Atherosclerosis of other type of bypass graft(s) of the right leg with ulceration of heel and midfoot
What it is
This code describes atherosclerotic narrowing or blockage in a bypass graft in the right leg, with an associated ulcer on the heel or midfoot. Use it when the record links the ulcer to the graft-related arterial disease.
Clinical signs
Findings may include a chronic nonhealing ulcer of the heel or midfoot, poor wound healing, and evidence of peripheral arterial disease in the bypass graft. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents atherosclerosis in an “other type” bypass graft of the right leg and specifies ulceration of the heel and/or midfoot. The ulcer location must be documented, and the right leg laterality must match the record. Check documentation if the graft type or ulcer site is unclear.
Do not use for
Do not use this code for ulcers without documented atherosclerosis of the bypass graft, or for disease in the left leg or unspecified leg. Do not use if the ulcer is not on the heel or midfoot.
Coding tip
Verify the graft type, laterality, and exact ulcer location before assigning I70.734.
