ICD-10 Code I70.248 – Atherosclerosis of native arteries of left leg with ulceration of other part of lower leg (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.248 – Atherosclerosis of native arteries of left leg with ulceration of other part of lower leg
What it is
This code identifies hardening and narrowing of the native arteries in the left leg, with an ulcer located on another part of the lower leg. Use it when the documentation links the ulcer to atherosclerotic disease in that limb.
Clinical signs
Findings often include peripheral arterial disease with poor blood flow to the left lower leg and a documented ulcer. Clinical features vary; refer to documentation for the ulcer site, chronicity, and whether the artery disease is native vessel disease.
When to use this code
Use I70.248 when the provider documents atherosclerosis of native arteries in the left leg and specifies an ulcer on another part of the lower leg, not the heel or midfoot. The record should clearly connect the ulcer to the arterial disease. Check documentation if laterality or ulcer location is unclear.
Do not use for
Do not use this code for ulcers without documented atherosclerosis, or for disease in the right leg or unspecified limb. Do not use it when the ulcer site is the heel or midfoot, because another code applies.
Coding tip
Verify both laterality and ulcer location in the note before assigning this code.
