What 33414 covers
Code 33414 represents surgical repair of the native aortic valve, preserving the patient’s valve rather than implanting a replacement. Cardiothoracic surgeons perform this operation in a hospital operating room; the operative report should identify the valve repair performed and distinguish it from aortic valve replacement. Medicare claims for this service are associated with facility care, consistent with its operative setting.
The code has a 90-day global period, which 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 applies the standard multiple-procedure reduction to the others. Modifier 50 is inappropriate for this valve procedure. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

33414 billing questions
When should 33414 be selected instead of an aortic valve replacement code?
Use 33414 when the surgeon repairs and preserves the patient’s native aortic valve. When the operative report documents removal of the native valve and implantation of a prosthetic valve or graft, select the applicable replacement code instead.
Does the 90-day global period include postoperative visits?
Yes. The global period includes the day-before preoperative visit and 90 days of related postoperative care.
How does Medicare handle 33414 with another procedure in the same session?
The highest-valued procedure is paid in full, and the other procedure or procedures are subject to the standard multiple-procedure reduction.
Can an assistant or co-surgeon be reported for 33414?
Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
Should modifier 50 be used for repair of the aortic valve?
No. Modifier 50 is inappropriate for this procedure because bilateral adjustment does not apply to the anatomy or service.
What operative documentation supports 33414?
Document the aortic valve repair performed and whether the native valve was preserved. The record should make clear that the service was repair rather than valve replacement.
