What 33894 covers

This service repairs disease of the descending thoracic aorta or aortic arch by delivering a branched endograft through vascular access and positioning it to exclude the diseased aortic segment while preserving flow through one branch vessel. Vascular or cardiothoracic surgeons typically perform it in an operating room or hybrid endovascular suite for conditions such as thoracic aortic aneurysm or dissection involving an arch branch. The branch-preserving graft configuration distinguishes this procedure from standard thoracic endografting.

Report the code when the documented repair uses a branched endograft involving one branch vessel; the operative report should support the aortic treatment and branch configuration. Associated radiological supervision and interpretation are included in the procedure. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When other procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. Modifier 50 is inappropriate for this service. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
