CPT code 33366: TAVR, transapical approach2026 Medicare rate & RVUs

Medicare pays $1,400.50 for 33366 nationally in a facility.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 33366 covers

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.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
