What 33362 covers
This procedure replaces the aortic valve using a catheter introduced through a surgically exposed femoral artery. It is an option for a patient undergoing transcatheter treatment of aortic stenosis when open femoral access is used rather than a needle puncture through the skin. An interventional cardiologist and cardiac surgeon may work together in a catheterization laboratory or hybrid operating room. The valve is delivered through the femoral access site and positioned within the diseased aortic valve; the surgical opening is the access route, not an open surgical replacement of the valve.
Select 33362 from the documented route of access, specifically a femoral artery exposed by incision. Document the access method and valve implantation. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures at 50%. Modifier 50 is inappropriate for this valve procedure. An assistant surgeon requires documentation of medical necessity; co-surgeons are permitted, while team surgery requires supporting documentation.

33362 billing questions
When is 33362 used instead of 33361?
Use 33362 when the femoral artery is surgically exposed for valve delivery. Use 33361 when femoral access is percutaneous.
Does an open femoral incision make this an open surgical valve replacement?
No. In 33362, the incision provides arterial access; the prosthetic valve is delivered and implanted by catheter.
Is same-day postoperative care separately reported?
CMS assigns 33362 a 0-day global period that includes same-day preoperative and postoperative care.
Can modifier 50 be used for femoral access?
No. The bilateral adjustment is inappropriate for this aortic valve procedure, even though femoral arteries exist on both sides.
How does CMS treat multiple procedures and additional surgeons?
In the same session, the highest-valued procedure is paid in full and other procedures at 50%. An assistant surgeon requires documentation of medical necessity; co-surgeons are permitted, and team surgery requires supporting documentation.
