What 33364 covers

This service replaces the aortic valve with a prosthetic valve delivered by catheter through an iliac artery that has been surgically exposed. A cardiac surgeon and interventional cardiologist may perform the procedure in a hospital hybrid operating room or catheterization laboratory, commonly for a patient with aortic stenosis when the iliac route is selected for valve delivery.

Select the code from the documented access route: 33364 identifies open iliac artery access. The operative report should establish the vessel exposed, the route used to deliver the valve, and valve deployment. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. For qualifying procedures performed in the same session, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment requires medical-necessity documentation; co-surgeons are permitted, and team surgery requires supporting documentation.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

33364 billing questions

How is 33364 distinguished from other TAVR approach codes?

Choose 33364 when the valve is delivered through open iliac artery access. The operative report should identify the exposed vessel and delivery route.

Can modifier 50 be reported?

No. The aortic valve anatomy and procedure make a bilateral adjustment inappropriate.

What preoperative or postoperative care is included?

CMS assigns a 0-day global period, which includes same-day preoperative and postoperative care.

How does the multiple-procedure reduction work?

When qualifying procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%.

What documentation is needed for additional surgeons?

Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeons are permitted; team surgery 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.
