What 33390 covers
This operation widens or repairs a narrowed native aortic valve while preserving the valve rather than replacing it. A cardiothoracic surgeon performs the repair in an operating room, commonly for aortic stenosis when the surgical plan is to improve valve opening. The procedure uses cardiopulmonary bypass. The operative report should describe the valve abnormality, repair performed, and surgical approach; code 33391 is the related transventricular approach.
Report 33390 when the documented procedure matches its open, bypass-supported approach. 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, Medicare pays the highest-valued procedure in full and reduces others to 50%. An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation, while team surgery is not permitted.

33390 billing questions
How does 33390 differ from 33391?
Both describe open aortic valve valvuloplasty with cardiopulmonary bypass. Use 33391 when the operative report documents the transventricular approach; use 33390 for the other approach described by its code.
When should the repair be coded as valve replacement instead?
Use a replacement code when the surgeon removes or replaces the native aortic valve rather than repairing and preserving it. The operative report should establish which procedure was performed.
What documentation supports 33390?
Document the aortic valve condition, the repair performed, the open approach, and use of cardiopulmonary bypass. Include enough operative detail to distinguish the procedure from the transventricular approach represented by 33391.
How does the 90-day global period affect related care?
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?
An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
