ICD-10 Code I72 – Other aneurysm (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I72 – Other aneurysm
What it is
I72 identifies an aneurysm in a location not classified elsewhere in the ICD-10-CM system. It means an abnormal focal dilation of a blood vessel or related artery, documented as “other” rather than a site-specific code.
Clinical signs
Clinical features vary; refer to documentation. Aneurysms may be found on imaging, during evaluation of pain, pulsation, or a mass, or after rupture-related symptoms. Use the documented vessel and presentation when available.
When to use this code
Use I72 when the record clearly identifies an aneurysm, but the anatomic site is not captured by a more specific ICD-10-CM code. It is also appropriate when the provider documents “other aneurysm” without further detail. Check documentation if the vessel location is stated, because a site-specific code may apply instead.
Do not use for
Do not use I72 for aneurysms with a more specific code available, or when the documentation supports a different vascular disorder. Do not assume this code for screening or suspected aneurysm without confirmation.
Coding tip
Code the exact vessel and laterality if documented; otherwise, use I72 only when the record supports an unspecified “other” aneurysm.
