What 33881 covers
Code 33881 describes endograft repair of descending thoracic aortic disease, such as an aneurysm, dissection, or traumatic disruption, without coverage of the left subclavian artery origin. A vascular or cardiothoracic surgeon typically performs the repair in a hospital or other surgical facility, advancing the endograft through arterial access, commonly femoral or iliac. The code includes the initial device and any required extensions through the treated segment toward the celiac artery, along with imaging guidance, monitoring, radiological supervision and interpretation, and closure of the access site.
Select this code when the operative report supports descending thoracic aortic repair and confirms that the left subclavian artery origin is not covered; use 33880 when it is covered. Documentation should identify the aortic pathology, device deployment and coverage extent, and access closure. The day-before preoperative visit and 90 days of related postoperative care are included in the global period. For multiple procedures 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 and co-surgeons are permitted; team surgery is not permitted.

- This related thoracic endovascular repair code addresses a different endoprosthesis configuration. Select based on the device arrangement documented for the repair.
- 33875Aortic graft
- 33875 describes open graft repair of the descending thoracic aorta. Choose 33881 for endovascular endograft repair without left subclavian origin coverage.
- 33883Aortic extension
- 33883 describes delayed placement of a proximal extension prosthesis, rather than the initial endovascular thoracic aortic repair reported with 33881.
33881 billing questions
How does 33881 differ from 33880?
Use 33881 when the endograft repair does not cover the left subclavian artery origin. Use 33880 when the repair involves that coverage.
Are imaging and access-site closure separately reported?
The code includes imaging guidance, monitoring, radiological supervision and interpretation, and closure by any method as part of the endovascular repair.
Are required endograft extensions included?
Yes. The repair includes the initial endoprosthesis and extensions required to treat the descending thoracic aorta toward the celiac artery.
What supports selecting 33881?
Document the thoracic aortic condition, endograft deployment, treated extent, and whether the left subclavian artery origin was covered.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be made, and co-surgeons are permitted. Team surgery is not permitted.
How does the global period affect postoperative billing?
The day-before preoperative visit and 90 days of related postoperative care are included in the global period.
