ICD-10 Code I70.235 – Atherosclerosis of native arteries of right leg with ulceration of other part of foot (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.235 – Atherosclerosis of native arteries of right leg with ulceration of other part of foot
What it is
This code identifies atherosclerosis in the native arteries of the right leg, complicated by an ulcer on another part of the foot. Use it when documentation links the arterial disease to the foot ulcer.
Clinical signs
Findings may include peripheral arterial disease, reduced foot perfusion, and a documented ulcer on the right foot. Clinical features vary; refer to documentation for the exact ulcer location and arterial involvement.
When to use this code
Use this code when the record states right-leg native artery atherosclerosis and a foot ulcer, and the ulcer is not on the heel or midfoot. The documentation should connect the ulcer to the vascular disease. If the site or laterality is unclear, check documentation.
Do not use for
Do not use this code for ulcers without documented atherosclerosis, or when the ulcer is in a different foot location than described. Do not guess the laterality or ulcer site.
Coding tip
Confirm both laterality and ulcer location in the note before assigning I70.235.
