Atherosclerosis of aorta

This code signifies the hardening and narrowing of the aorta due to plaque buildup. It represents a systemic arterial disease affecting the body's largest artery, potentially leading to compromised blood flow to various organs.

Apply this code when documentation explicitly states atherosclerosis of the aorta. This includes findings from imaging studies (e.g., CT, MRI, angiography) or surgical reports describing atherosclerotic changes in the aortic wall.

• Do not use for atherosclerosis of other arteries; ensure the documentation specifies the aorta.
• Consider additional codes for any associated complications, such as aneurysm or dissection, if documented.
• This is a diagnosis code; it does not represent a procedure.
