Aneurysm of other specified arteries

This code signifies the presence of an aneurysm in an artery not specifically categorized elsewhere, such as the splenic, renal, or mesenteric arteries. It indicates a localized, abnormal dilation or ballooning of the arterial wall, posing a risk of rupture and hemorrhage.

Apply this code when documentation clearly identifies an aneurysm in a peripheral artery, visceral artery, or other non-cerebral, non-aortic, and non-coronary artery. Supporting documentation should include imaging reports (e.g., ultrasound, CT, MRI, angiography) confirming the aneurysm's location and presence.

• Always seek specific documentation of the affected artery. If the artery is not specified, query the provider.
• Do not use this code for aneurysms of the aorta (I71.-), cerebral arteries (I67.1), or coronary arteries (I25.4-).
• Code any associated complications, such as rupture (I72.8 with I72.80) or thrombosis, as additional diagnoses.
