What 33886 covers
This service extends a prior endovascular repair of the descending thoracic aorta by placing a prosthesis distally, toward the lower thoracic aorta. A vascular or cardiothoracic surgeon typically performs the catheter-based procedure in a hospital operating or endovascular suite using fluoroscopic imaging. It is distinct from placing the original thoracic endograft and from adding an extension at the proximal end.
Report the code when the operative record supports delayed distal extension placement after an earlier thoracic endovascular repair. Documentation should identify the prior repair, the reason for the later intervention, and the distal extension performed. Procedural imaging supervision and interpretation are included in the service. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery and co-surgeon services may be paid; team surgery is not permitted.
