Cardiac surgery
About 33475: Open pulmonary valve replacement
Reports open surgical replacement of the pulmonary valve when the operation replaces the valve rather than revising it or implanting one transcatheterly.
A cardiac surgeon reports this service for an operation that replaces the pulmonary valve, often for significant valve dysfunction in a patient with congenital heart disease or after prior cardiac surgery. It is performed in an operating room, generally in a hospital setting. The operative report should establish that the pulmonary valve was replaced, rather than revised or treated with a catheter-based implant.
Choose this code based on the procedure actually performed, not just the diagnosis or the presence of a prior valve operation. Document the operative approach, the valve treated, and any additional valve procedures. Medicare includes the day-before preoperative visit and 90 days of related postoperative care in the 90-day global period. 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 50% reduction. Modifier 50 is inappropriate for this code. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

33475 billing questions
How is this code distinguished from pulmonary valve revision?
Report this code when the operation replaces the pulmonary valve. Code 33474 is the nearby revision code; use it when the documented procedure is a revision rather than replacement.
How does this differ from a transcatheter pulmonary valve procedure?
This code describes open surgical replacement. Code 33477 is the transcatheter pulmonary valve option when the valve is implanted by catheter.
Does modifier 50 apply?
No. CMS identifies bilateral adjustment as inappropriate for this code because of the descriptor or anatomy.
What postoperative care is included in the global period?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant or co-surgeon be paid?
Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
How are other procedures in the same session paid?
The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple-procedure reduction, with payment at 50%.
