About 33422: Open mitral valvotomy with bypass
Reports open surgical division of fused mitral valve commissures under cardiopulmonary bypass to relieve stenosis while preserving the native valve.
A cardiac surgeon performs an open mitral valvotomy with cardiopulmonary bypass, directly addressing the stenotic valve and separating fused commissures to improve valve opening. This operation is used for selected patients with mitral stenosis when the native valve can be preserved; commissural fusion, often associated with rheumatic disease, is a typical finding. It is generally performed in a hospital operating room.
Choose this code for the open operation with bypass, not for a closed valvotomy, mitral valve repair, or valve replacement. The operative report should establish the open approach, use of bypass, stenotic pathology, and the valvotomy performed. 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 others at 50%. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation. Team surgery is not permitted.

33422 billing questions
How does 33422 differ from 33420?
33422 describes open mitral valvotomy with cardiopulmonary bypass. 33420 is the closed-heart mitral valvotomy code.
When is mitral repair or replacement reported instead?
Use a repair code when the operation reconstructs the valve rather than dividing fused commissures. Use a replacement code when the native valve is removed and replaced.
What should the operative report support?
Document the open approach, cardiopulmonary bypass, mitral stenosis, and the valve-opening procedure performed. The diagnosis alone does not establish that this operation was done.
Can modifier 50 be reported?
No. The bilateral adjustment does not apply to this single mitral valve operation, and modifier 50 is inappropriate.
How are other procedures in the same session paid?
Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and other procedures are paid at 50%. The 90-day global period includes related postoperative care.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
