About 33406: Open aortic valve homograft or stentless replacement
Open replacement of a diseased aortic valve using a homograft or stentless valve, reported when the operative record supports that implant type.
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.

33406 billing questions
How is 33406 different from 33405?
33406 applies when the operative record identifies a homograft or stentless valve. Code 33405 is for a prosthetic valve other than those types.
Is cardiopulmonary bypass included?
Yes. The code describes open aortic valve replacement performed with cardiopulmonary bypass.
Can another procedure be reported during the same operation?
A separately reportable procedure may be subject to the standard multiple procedure reduction when performed in the same session. The operative documentation must support each reported service.
Which modifiers or surgical assistance rules should the biller consider?
Modifier 50 is inappropriate. CMS may pay an assistant at surgery, while co-surgeon payment requires supporting documentation; team surgery payment is not permitted.
What care is included in the global period?
The 90-day global includes the day-before preoperative visit and 90 days of related postoperative care.
