ICD-10 Code I70.2 – Atherosclerosis of native arteries of the extremities (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.2 – Atherosclerosis of native arteries of the extremities
What it is
This code identifies plaque buildup in the patient’s own leg or arm arteries, causing narrowing or blockage. Use it when documentation states atherosclerosis of native extremity arteries without a more specific site.
Clinical signs
Patients may have limb pain with walking, reduced pulses, cool skin, or poor wound healing. Clinical features vary; refer to documentation.
When to use this code
Use I70.2 when the provider documents atherosclerosis affecting native arteries of an extremity and does not specify a more detailed subcategory. It fits chronic peripheral arterial disease descriptions involving the patient’s own arteries. Check documentation if the record also mentions ulceration, gangrene, or bypass graft involvement.
Do not use for
Do not use this code for atherosclerosis of bypass grafts, implanted devices, or non-native vessels. If the note describes another vascular disorder or a more specific atherosclerosis site, code that instead.
Coding tip
Verify whether the documentation names native arteries, because graft-related disease requires a different code.
