ICD-10 Code I70.244 – Atherosclerosis of native arteries of left leg with ulceration of heel and midfoot (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.244 – Atherosclerosis of native arteries of left leg with ulceration of heel and midfoot
What it is
This code identifies atherosclerosis in the native arteries of the left leg with an associated ulcer on the heel and midfoot. Use it when documentation links the arterial disease to a left-sided lower-extremity ulcer in those locations.
Clinical signs
Typical findings include peripheral arterial disease with reduced blood flow to the left leg and a documented ulcer involving the heel or midfoot. Clinical features vary; refer to documentation.
When to use this code
Use I70.244 when the provider documents atherosclerosis of native arteries in the left leg and specifies ulceration of the heel and midfoot. The ulcer site must be clearly stated, and the record should support atherosclerotic arterial disease rather than another cause. If laterality or ulcer location is unclear, check documentation.
Do not use for
Do not use this code for ulcers without documented atherosclerosis, or when the ulcer is on a different limb or site. Do not apply it if the arterial disease is in bypass grafts or if the documentation does not specify native arteries.
Coding tip
Confirm both laterality and ulcer location in the note before assigning I70.244.
