What 33859 covers

A cardiothoracic surgeon uses this code for open graft replacement of the ascending aorta when the underlying condition is not an aortic dissection. A typical case is repair of an ascending aortic aneurysm. These operations are generally performed in an operating room, often with cardiopulmonary bypass. The operative report should establish the treated aortic segment, the non-dissection diagnosis, and the graft replacement performed.

Report this code for the non-dissection ascending-aortic procedure, distinguishing it from dissection repair and from procedures with a more specific aortic-root description. The major-surgery global period includes the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in the same session, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 is not appropriate for this aortic service. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
