What 33405 covers

A cardiac surgeon removes the diseased aortic valve and implants a prosthesis during open surgery, typically using cardiopulmonary bypass. Common indications include severe aortic stenosis or regurgitation requiring surgical replacement. The implanted valve may be mechanical or a stented tissue prosthesis; this code distinguishes those options from a homograft or stentless tissue valve. These operations are performed in a hospital operating room, and CMS recorded 18,664 facility services for the code in 2024.

Report the code when the operative record supports open aortic valve replacement and identifies the implanted prosthesis sufficiently to distinguish it from the valve types represented by neighboring codes. 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 subject to the standard multiple-procedure reduction. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
