ICD-10 Code I70.332 – Atherosclerosis of unspecified type of bypass graft(s) of the right leg with ulceration of calf (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.332 – Atherosclerosis of unspecified type of bypass graft(s) of the right leg with ulceration of calf
What it is
This code describes atherosclerotic narrowing or blockage in an unspecified bypass graft in the right leg, with an associated ulcer on the calf. Use it when the graft site and ulcer location are documented as such.
Clinical signs
Typical findings include reduced blood flow to the right leg, chronic limb ischemia, and a nonhealing calf ulcer. Clinical features vary; refer to documentation for graft type, laterality, and ulcer details.
When to use this code
Use I70.332 when the record clearly states atherosclerosis affects an unspecified bypass graft in the right leg and the patient has an ulcer of the calf. The ulcer must be linked to the vascular disease in the documentation. If the graft type, laterality, or ulcer site is unclear, check documentation before coding.
Do not use for
Do not use this code for ulcers without documented atherosclerosis of a bypass graft, or when the lesion is on another leg or another site. Check documentation if the graft type is specified differently.
Coding tip
Confirm the bypass graft is in the right leg and that the calf ulcer is documented as associated with the atherosclerotic disease.
