2026 ICD-10-CM Diagnosis Code I70.532 – Atherosclerosis of nonautologous biological bypass graft(s) of the right leg with ulceration of calf
What it is
This code describes narrowing or blockage from atherosclerosis in a nonautologous biological bypass graft in the right leg, with an ulcer on the calf. Use it when the graft and ulcer are both documented.
Clinical signs
Findings may include reduced blood flow in the right leg, poor wound healing, and a documented calf ulcer. Clinical features vary; refer to documentation.
When to use this code
Use I70.532 when the record specifically identifies a nonautologous biological bypass graft in the right leg and notes ulceration of the calf. The ulcer location should match the documentation. Check documentation if the graft type, laterality, or ulcer site is unclear.
Do not use for
Do not use this code if the ulcer is on a different leg or another site, or if the graft type is not a nonautologous biological bypass graft. Check documentation.
Coding tip
Confirm laterality, graft type, and ulcer location in the operative or vascular note before assigning this code.
