What 33406 covers

Code 33406 represents open aortic valve replacement performed with cardiopulmonary bypass using a homograft or stentless valve. A cardiac surgeon removes the diseased native valve and implants the selected replacement during major heart surgery, typically in a hospital operating room. The implanted valve type—not simply the diagnosis or the fact that the valve is biologic—distinguishes this service from other aortic valve replacement coding.

Report the code when the operative record supports open replacement, cardiopulmonary bypass, and use of a homograft or stentless valve. The procedure has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. CMS may pay an assistant at surgery; co-surgeon payment requires supporting documentation, and team surgery payment is not permitted. Modifier 50 is inappropriate for this code.
