ICD-10 Code I70.245 – Atherosclerosis of native arteries of left leg with ulceration of other part of foot (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.245 – Atherosclerosis of native arteries of left leg with ulceration of other part of foot
What it is
This code identifies atherosclerosis in the native arteries of the left leg with an associated ulcer on another part of the foot. Use it when the record clearly links the arterial disease to the ulcer.
Clinical signs
Typical findings include peripheral arterial disease in the left lower extremity and a documented foot ulcer in a non-heel, non-toe location. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents atherosclerosis of native left leg arteries and specifies ulceration of another foot site. The ulcer location should be documented clearly, and the condition should be tied to the left leg arterial disease. Check documentation if laterality or ulcer site is unclear.
Do not use for
Do not use this code for atherosclerosis without ulceration, or for ulcers not linked to arterial disease. Do not use it when the ulcer is on the heel or toe, or when the laterality is not left. Check documentation.
Coding tip
Confirm both the arterial disease and the exact ulcer location before assigning I70.245.
