Infrarenal abdominal aortic aneurysm, without rupture

This code identifies an aneurysm located in the abdominal aorta, specifically below the renal arteries, that has not ruptured. It signifies a localized dilation of the infrarenal segment of the aorta, indicating a weakening of the vessel wall.

Apply this code when documentation clearly states an infrarenal abdominal aortic aneurysm without evidence of rupture. This is typically diagnosed via imaging studies such as ultrasound, CT, or MRI. The physician's report must explicitly confirm the location and absence of rupture.

• Ensure documentation specifies "infrarenal" to differentiate from other abdominal aortic aneurysm locations.
• Do not use this code if rupture is present; refer to the appropriate ruptured aneurysm codes.
• Confirm the absence of rupture; if rupture is suspected but not confirmed, query the provider.
