ICD-10 Code I70.232 – Atherosclerosis of native arteries of right leg with ulceration of calf (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.232 – Atherosclerosis of native arteries of right leg with ulceration of calf
What it is
This code identifies atherosclerosis in the native arteries of the right leg when it is associated with an ulcer on the calf. It documents both the arterial disease and the ulcer location on the right lower extremity.
Clinical signs
Typical findings include peripheral arterial disease with poor blood flow, a nonhealing calf ulcer, and signs of ischemic tissue injury. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly states atherosclerosis of the native arteries of the right leg and documents an ulcer of the calf. The ulcer must be linked to the arterial disease, not described as venous, diabetic, pressure-related, or traumatic.
Choose this code when laterality and site are specified as right leg and calf. If the documentation does not confirm the ulcer cause or location, check documentation before coding.
Do not use for
Do not use this code for ulcers from other causes, such as pressure, diabetes, venous disease, or injury. It is also incorrect if the record does not identify native right leg arteries or the calf site.
Coding tip
Verify that the provider links the ulcer to atherosclerosis and documents the right leg and calf location before assigning I70.232.
