About 33364: Transcatheter aortic valve replacement via iliac access
Reports transcatheter aortic valve replacement when the prosthetic valve is delivered through surgically exposed iliac artery access.
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.

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