What 33363 covers
This code describes TAVR using an open axillary artery approach: the artery is surgically exposed to deliver and deploy a prosthetic aortic valve. The valve is placed by catheter rather than through conventional open valve replacement. The procedure is typically performed by a cardiac surgery and interventional cardiology team in a hospital operating room or hybrid suite for a patient with aortic valve disease, commonly severe aortic stenosis, when axillary access is selected.
Select this code based on the documented access route, not simply because the procedure is called “open.” The operative report should identify surgical exposure of the axillary artery and transcatheter valve delivery. CMS assigns 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 other procedures are subject to the standard 50% reduction. Assistant-at-surgery payment requires documented medical necessity; co-surgeons are permitted, and team-surgery payment requires supporting documentation.

- Both describe TAVR with open arterial access. Choose 33362 for the femoral artery and 33363 for the axillary artery.
- 33364TAVR
- This is the open iliac artery access option; 33363 identifies open axillary artery access.
- 33361TAVR
- This describes TAVR using percutaneous femoral access. Code 33363 requires surgical exposure of the axillary artery.
- 33366TAVR
- This identifies the transapical TAVR route, not open axillary artery access.
33363 billing questions
How does 33363 differ from conventional open aortic valve replacement?
The valve is delivered and deployed by catheter through surgically exposed axillary artery access. It does not describe direct surgical replacement of the valve through an open-heart approach.
How do I choose between 33363 and 33362?
Use 33363 for open axillary artery access and 33362 for open femoral artery access. The documented access route distinguishes these TAVR codes.
Does the 0-day global period include same-day care?
Yes. CMS includes same-day preoperative and postoperative care in the 0-day global period.
Can an assistant surgeon or co-surgeon be reported?
Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeons are permitted; team-surgery payment requires supporting documentation.
Should modifier 50 be used for bilateral access?
No. CMS identifies bilateral adjustment as inappropriate for this code.
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.
