Aortic aneurysm of unspecified site without mention of rupture

This code signifies an abnormal localized dilation of the aorta, the body's largest artery, where the specific anatomical location of the aneurysm (e.g., thoracic, abdominal) is not documented. It indicates that the aneurysm has not ruptured, meaning the arterial wall remains intact.

This code is appropriate when documentation clearly states "aortic aneurysm" but provides no further specificity regarding its location within the aorta. It should be used when the physician explicitly notes that there is no evidence of rupture. Supporting documentation would include imaging reports (e.g., ultrasound, CT, MRI) or physician notes identifying an aortic aneurysm without site specification or mention of rupture.

• Avoid using this code if the aneurysm's site (e.g., thoracic, abdominal) is documented; instead, use a more specific code.
• Do not use this code if rupture is indicated; select a code that specifies rupture.
• Query the provider for clarification on the aneurysm's site if possible, to allow for more precise coding.
