Pararenal abdominal aortic aneurysm, without rupture

This code signifies a localized dilation of the abdominal aorta, specifically in the pararenal segment (adjacent to the kidneys), that has not ruptured. It represents an abnormal widening of the arterial wall in this region, posing a risk for future rupture if untreated.

Use this code when documentation clearly states a diagnosis of an abdominal aortic aneurysm located in the pararenal region, and explicitly confirms the absence of rupture. This is typically identified through imaging studies such as CT angiography or ultrasound.

• Ensure documentation specifies "pararenal" location to differentiate from infrarenal or juxtarenal aneurysms.
• Confirm the absence of rupture; if ruptured, a different code from the I71.3 or I71.4 series would be appropriate.
• Do not confuse with I71.42 (juxtarenal) or I71.43 (infrarenal) without specific documentation of pararenal involvement.
