What 33391 covers
A cardiothoracic surgeon opens the heart and operates on the native aortic valve using cardiopulmonary bypass to relieve congenital stenosis. The goal is to improve valve opening while retaining the patient’s own valve, rather than implanting a replacement. This major operation is generally performed in a hospital operating room; Medicare recorded facility services for the code in 2024 and no office services.
Choose this code when the operative report supports open aortic valvuloplasty for congenital stenosis with bypass. Documentation should identify the congenital valve problem, the open repair performed, and use of cardiopulmonary bypass. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are paid at 50%. Modifier 50 is not appropriate for this single aortic valve operation. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation. CMS does not permit team surgery payment for this procedure.
