Cardiac surgery
About 33496: Thrombus repair of prosthetic heart valve
Open cardiac surgery with cardiopulmonary bypass to clear thrombus affecting an existing prosthetic heart valve when the valve is repaired rather than replaced.
A cardiac surgeon uses cardiopulmonary bypass to address thrombus obstructing or impairing an implanted prosthetic heart valve. The operation treats the clot-related problem while retaining and repairing the prosthesis, rather than removing it for valve replacement. It is a facility-based cardiac surgery service, not a separately reported diagnostic or catheter-based clot treatment.
Report the code when the operative work addresses thrombus involving a prosthetic valve. The operative report should identify the affected valve, document the thrombus and the repair performed, and clarify whether the prosthesis was retained or replaced. Medicare assigns 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. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation. Team surgery is not permitted.

33496 billing questions
How is this code distinguished from a valve replacement code?
Use this code when surgery treats thrombus affecting a prosthetic valve and the valve is retained and repaired. If the surgeon removes the prosthesis and implants a replacement, select the applicable replacement code instead.
Does this code include replacement of the prosthetic valve?
No. It describes repair directed at the thrombus problem with the prosthesis retained; replacement is a different operative service.
What documentation supports reporting this service?
The operative report should identify the prosthetic valve involved, describe the thrombus and the repair, and make clear whether the prosthesis was retained or replaced.
How does the 90-day global period affect postoperative reporting?
The day-before preoperative visit and 90 days of related postoperative care are included in the global period.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation.
