ICD-10 Code I70.268 – Atherosclerosis of native arteries of extremities with gangrene, other extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.268 – Atherosclerosis of native arteries of extremities with gangrene, other extremity
What it is
This code identifies atherosclerosis in a native artery of an extremity when gangrene is present in an other, unspecified extremity. Use it when the record documents both peripheral arterial disease and tissue death from poor blood flow.
Clinical signs
Typical findings include a poorly perfused limb with black, necrotic, or dead tissue and signs of chronic arterial insufficiency. Clinical features vary; refer to documentation for the affected extremity and whether gangrene is dry or wet.
When to use this code
Use this code when the provider documents atherosclerosis of a native extremity artery with gangrene and the affected limb is not otherwise specified as lower or upper. It supports cases where the documentation clearly links gangrene to arterial disease. Check documentation if the site of the extremity is unclear.
Do not use for
Do not use this code for atherosclerosis without gangrene, or for gangrene from trauma, infection, or diabetes alone. If the record names a different extremity or a bypass graft, choose the more specific documented code.
Coding tip
Verify that “native artery” and “other extremity” are both documented before assigning I70.268.
