Abdominal aortic aneurysm, without rupture, unspecified

This code signifies an abdominal aortic aneurysm (AAA) that has not ruptured and where the specific location or extent of the aneurysm within the abdominal aorta is not documented. It represents a localized dilation of the abdominal aorta, exceeding its normal diameter, without evidence of acute hemorrhage or dissection.

Use this code when documentation clearly states an unruptured abdominal aortic aneurysm but lacks further specificity regarding its precise anatomical segment (e.g., juxtarenal, infrarenal). This code is appropriate when the physician's assessment confirms an AAA without rupture, and no additional details are provided in the medical record.

• Avoid using this code if the documentation specifies the aneurysm's location (e.g., infrarenal, juxtarenal); instead, use a more specific I71.4x code.
• Ensure the documentation explicitly states "without rupture" or implies an intact aneurysm; otherwise, consider codes for ruptured aneurysms.
• This code is often a placeholder when initial documentation is vague, and coders should query for more specific anatomical detail if available.
