Cardiac surgery
About 33405: Open aortic valve replacement with prosthesis
Reports open surgical replacement of a diseased aortic valve using a conventional prosthesis, such as a mechanical or stented tissue valve.
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.

33405 billing questions
When is 33405 selected instead of 33406 or 33410?
Use 33405 for a conventional prosthesis, such as a mechanical or stented tissue valve. The neighboring codes distinguish homograft and stentless tissue valve procedures.
What operative documentation supports 33405?
The operative report should establish open replacement of the aortic valve and identify the implanted valve type. This supports selecting the code rather than one for a homograft or stentless tissue valve.
How does the global period affect postoperative reporting?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
How are other procedures from the same session paid?
The highest-valued procedure is paid in full; other procedures performed in the same session are subject to the standard multiple-procedure reduction.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation, and team surgery is not permitted.
