ICD-10 Code I70.732 – Atherosclerosis of other type of bypass graft(s) of the right leg with ulceration of calf (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.732 – Atherosclerosis of other type of bypass graft(s) of the right leg with ulceration of calf
What it is
This code identifies atherosclerotic narrowing in an other type of bypass graft in the right leg, with an ulcer located on the calf. Use it when the record links the graft disease and the ulcer to the same limb.
Clinical signs
Findings may include poor limb perfusion, diminished pulses, delayed wound healing, and a chronic ulcer on the right calf. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents atherosclerosis affecting an other type of bypass graft in the right leg and specifies ulceration of the calf. The ulcer must be documented as part of the same condition, not as a separate unrelated wound. Check documentation for laterality and graft type.
Do not use for
Do not use this code if the ulcer site, leg laterality, or graft type is not documented. Do not use it for native-vessel peripheral arterial disease or for ulcers unrelated to the bypass graft.
Coding tip
Verify the operative history and the exact ulcer location before assigning I70.732.
