ICD-10 Code I70.239 – Atherosclerosis of native arteries of right leg with ulceration of unspecified site (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.239 – Atherosclerosis of native arteries of right leg with ulceration of unspecified site
What it is
This code identifies atherosclerosis in the native arteries of the right leg with an associated ulcer at an unspecified site. Use it when documentation links the ulcer to peripheral arterial disease in the right lower extremity.
Clinical signs
Findings may include diminished pulses, cool skin, leg pain with walking, and poor wound healing. Clinical features vary; refer to documentation for the ulcer location and evidence of arterial disease.
When to use this code
Use I70.239 when the record states atherosclerosis of native right leg arteries and an ulcer is present, but the ulcer site is not specified. The diagnosis should clearly connect the ulcer to the arterial disease. If the documentation names a more specific ulcer location, code that level instead.
Do not use for
Do not use this code for venous, diabetic, pressure, or traumatic ulcers without documented arterial atherosclerosis. Check documentation if the ulcer is not linked to the right leg or if the site is specified differently.
Coding tip
Verify that the record states both right-leg atherosclerosis and ulceration before assigning this code.
