Congenital insufficiency of aortic valve

This code signifies a structural defect of the aortic valve present at birth, leading to its inability to close completely. This insufficiency results in a backflow of blood from the aorta into the left ventricle during diastole, increasing cardiac workload.

Assign this code when documentation clearly indicates a congenital origin for aortic valve regurgitation or incompetence. This is typically supported by echocardiogram findings detailing the valve anomaly and a physician's diagnosis of congenital aortic insufficiency.

• Differentiate from acquired aortic insufficiency (e.g., rheumatic, degenerative), which would be coded elsewhere.
• Look for specific physician documentation stating "congenital" or "present at birth" in relation to the aortic valve insufficiency.
• Consider sequencing with other congenital heart defects if present, following official coding guidelines.
