About 33877: Thoracoabdominal aortic graft replacement
Reports open graft replacement of a diseased aortic segment extending through the chest and abdomen, with or without cardiopulmonary bypass.
This code describes open replacement of a thoracoabdominal aortic segment with a graft, commonly during repair of an aneurysm or other serious aortic disease. The operation is generally performed by vascular or cardiothoracic surgeons in a hospital operating room. Cardiopulmonary bypass may be used, but its use does not change selection of this code. The operative report should identify the aortic extent treated and document graft replacement.
Report the code for the thoracoabdominal repair rather than a graft procedure limited to the thoracic aorta. Medicare assigns a 90-day global period: the day-before preoperative visit and 90 days of related postoperative care are included. 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% multiple-procedure reduction. Modifier 50 is not appropriate for this anatomy. Assistant-at-surgery payment and co-surgeon billing are permitted; team surgery is not permitted.
