ICD-10 Code I70.234 – Atherosclerosis of native arteries of right leg with ulceration of heel and midfoot (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.234 – Atherosclerosis of native arteries of right leg with ulceration of heel and midfoot
What it is
This code identifies peripheral atherosclerosis in the native arteries of the right leg when there is an associated ulcer on the heel or midfoot. It combines the vascular disease site, laterality, and ulcer location.
Clinical signs
Findings may include reduced blood flow to the right foot, nonhealing ulceration, pain, cool skin, diminished pulses, or tissue loss. Clinical features vary; refer to documentation.
When to use this code
Use I70.234 when the record clearly documents atherosclerosis of native right leg arteries with an ulcer specifically on the heel or midfoot. The ulcer must be linked to the arterial disease, not another cause. Confirm laterality and ulcer site in the note.
Do not use for
Do not use this code for ulcers without documented atherosclerosis, or for ulcers in other locations. Check documentation if the ulcer is caused by diabetes, pressure, venous disease, or trauma.
Coding tip
Verify both the arterial diagnosis and the exact ulcer location before assigning the code.
