Structural heart intervention
About 33366: Transapical transcatheter aortic valve replacement
Reports aortic valve replacement using a catheter-delivered prosthesis introduced through the heart’s apex rather than a peripheral artery.
This code represents transcatheter aortic valve replacement performed through a surgical opening at the heart’s apex. A cardiothoracic surgeon, often working with an interventional cardiologist as part of a heart team, introduces the prosthetic valve through the left ventricular apex and advances it across the native aortic valve. The procedure is typically performed in a hospital operating room or hybrid suite for a patient who needs aortic valve replacement and whose planned access route is transapical.
Select the code from the documented access route: transapical access distinguishes this service from peripheral arterial and transaortic approaches. The operative report should support valve implantation and identify the route; report a bypass-specific family code when cardiopulmonary bypass is used. This procedure has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard multiple procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment requires medical-necessity documentation; co-surgeons are permitted, and team-surgery payment requires supporting documentation.

33366 billing questions
When should 33366 be selected instead of another TAVR code?
Use 33366 when the prosthetic valve is delivered through transapical access at the heart’s apex. The documented route, rather than the diagnosis alone, distinguishes it from other TAVR approach codes.
How does 33366 differ from a bypass-specific TAVR code?
33366 identifies the transapical approach without the bypass-specific designation. If cardiopulmonary bypass is used, select the applicable bypass code for the documented approach.
Can modifier 50 be reported?
No. The CMS bilateral adjustment does not apply to this code, and modifier 50 is inappropriate for the procedure.
Is same-day postoperative care included?
Yes. The 0-day global period includes same-day preoperative and postoperative care.
When is assistant-at-surgery payment allowed?
Payment for an assistant at surgery requires documentation that the assistant was medically necessary. Co-surgeons are permitted, while team-surgery payment requires supporting documentation.
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 performed in that session are paid at 50%.
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.
