ICD-10 Code I72.8 – Aneurysm of other specified arteries (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I72.8 – Aneurysm of other specified arteries
What it is
This code identifies an aneurysm in an artery that is not named in a more specific ICD-10 category. Use it when the record clearly documents an arterial aneurysm, but the vessel is described only as “other specified.”
Clinical signs
Clinical features vary; refer to documentation. Imaging may show focal arterial dilatation, and the report should identify an aneurysm in a specified artery that is not covered by a more precise code.
When to use this code
Use I72.8 when the provider documents an aneurysm of an artery that is specified, but no dedicated code exists for that vessel. It may appear in imaging, operative, or specialist notes. If the artery is named and a more specific code exists, use that code instead.
Do not use for
Do not use this code for aortic aneurysm, cerebral aneurysm, or arteriovenous malformation. Check documentation if the vessel is not clearly identified or if the condition is described only as arterial ectasia.
Coding tip
Code the artery named in the record first, then confirm that I72.8 is the most specific available option.
