About 33335: Aortic graft placement with bypass
Reports placement of an aortic graft during open surgery using cardiopulmonary bypass to support circulation while the aorta is treated.
This code captures placement of an aortic graft during an operation that uses cardiopulmonary bypass (CPB). A cardiac surgeon performs the reconstruction in an operating room, commonly when an aortic segment requires graft replacement or reconstruction. CPB supports circulation while the aorta is treated. The operative report should identify the aortic work and document use of bypass.
Report the code when the documented service is aortic graft placement with CPB, rather than direct vessel repair or graft placement without bypass. Documentation should establish the aortic segment treated, graft reconstruction, and CPB. The code has a 90-day global period: the day-before preoperative visit and 90 days of related postoperative care are included. For same-session multiple procedures, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

What documentation supports reporting this code?
The operative report should describe the aortic segment treated, graft placement or reconstruction, and use of cardiopulmonary bypass.
Are related postoperative visits separately included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation, while team surgery is not permitted.
Can modifier 50 be used for bilateral work?
