Rheumatic aortic insufficiency

This code identifies a condition where the aortic valve, due to rheumatic fever, fails to close completely, leading to a backflow of blood into the left ventricle during diastole. This insufficiency can cause symptoms such as shortness of breath, fatigue, and chest pain, and may progress to heart failure if untreated.

Use this code when documentation explicitly states "rheumatic aortic insufficiency" or "rheumatic aortic regurgitation." It is appropriate for both acute and chronic presentations of valve dysfunction stemming from a history of rheumatic fever. Ensure the physician's notes clearly link the valvular disease to a rheumatic etiology.

• Distinguish from non-rheumatic causes of aortic insufficiency (e.g., degenerative, congenital); a different code would apply.
• Always look for documentation of the underlying cause (rheumatic fever) to support this specific code.
• Consider co-reporting with codes for heart failure if present, as aortic insufficiency can lead to cardiac decompensation.
