Cardiac surgery
About 33845: Aortic coarctation excision with graft
Open repair of aortic coarctation by removing the narrowed segment and restoring aortic continuity with a graft.
A cardiothoracic surgeon removes a narrowed segment of the aorta caused by coarctation and reconstructs the vessel with a graft. The operation treats congenital narrowing of the thoracic aorta when the surgeon uses graft reconstruction rather than joining the remaining aortic ends directly. It is performed in an operating room, generally as an open cardiac or vascular procedure.
Report this code when the operative record supports both excision of the coarctation and graft reconstruction; a direct end-to-end repair is a different technique. Documentation should identify the treated aortic segment, the excision, and the graft repair. This major operation has a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. 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 may be made; co-surgeon payment requires supporting documentation. Team surgery is not permitted, and modifier 50 is inappropriate.

33845 billing questions
How does this differ from 33840?
Code 33845 describes excision followed by graft reconstruction. Code 33840 is for excision with direct anastomosis of the aortic ends.
What operative documentation supports 33845?
The operative report should establish that the coarctation was excised and that a graft was used to reconstruct the aorta. A graft repair without documented excision may not support this code.
Is the preoperative visit or routine postoperative care separately reported?
The day-before preoperative visit and related postoperative care during the 90-day global period are included in the global surgical payment.
Can modifier 50 be used?
No. CMS identifies bilateral adjustment as inappropriate for this code.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation, and team surgery is not permitted.
