CPT code 33361: TAVR, percutaneous femoral approach2026 Medicare rate & RVUs in Maryland

CMS doesn’t publish an office rate for 33361 in Maryland.

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

What 33361 covers

Code 33361 reports transcatheter aortic valve replacement for a patient whose prosthetic valve is delivered through percutaneous femoral arterial access. The procedure treats aortic valve disease such as aortic stenosis. An interventional cardiologist and cardiac surgeon commonly perform the procedure together in a hospital catheterization laboratory or hybrid operating room. The operative record should identify the valve replacement and show that the femoral artery was accessed percutaneously rather than exposed surgically or approached through another route.

Select 33361 based on the access route, not simply because a TAVR occurred. Document the approach and any conversion to a different access method. Medicare assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons are permitted, and team-surgery payment requires supporting documentation.

33367TAVR bypass supportWith cardiopulmonary bypass

33367 describes TAVR with cardiopulmonary bypass using percutaneous femoral access; 33361 identifies the percutaneous femoral approach without that bypass distinction.
