ICD-10 Code I70.238 – Atherosclerosis of native arteries of right leg with ulceration of other part of lower leg (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.238 – Atherosclerosis of native arteries of right leg with ulceration of other part of lower leg
What it is
This code identifies atherosclerosis in the native arteries of the right leg with an associated ulcer on another part of the lower leg. Use it when documentation links the ulcer to arterial disease in the right lower extremity.
Clinical signs
Typical findings include peripheral arterial disease with a lower-leg ulcer and evidence of reduced blood flow. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents atherosclerosis of native right leg arteries and specifies an ulcer on another part of the lower leg. The ulcer location must match the documented site, and the relationship to arterial disease should be clear. Check documentation if laterality or ulcer site is unclear.
Do not use for
Do not use this code for ulcers without documented arterial atherosclerosis or when the affected leg is not the right leg. Do not use it if the ulcer site is different from the documented “other part of lower leg.”
Coding tip
Verify both laterality and ulcer location in the note before assigning I70.238.
