What 34712 covers
This service covers catheter-based placement of enhanced fixation devices to secure an aortic endograft during endovascular repair of an infrarenal abdominal aortic aneurysm or dissection. The devices reinforce graft attachment to the aortic wall. Vascular surgeons and other physicians performing endovascular aortic repair typically deliver them in an operating room or hybrid suite, using imaging guidance as needed.
Report 34712 for the fixation-device delivery performed at the time of the aortic repair, not for placement of an extension graft or for the repair itself. Documentation should identify the repair, the fixation-device delivery, and its clinical purpose. The CMS global period is 90 days and includes the day-before preoperative visit and related postoperative care during that period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. Assistant-at-surgery payment and co-surgeon reporting are permitted; team surgery is not permitted.

34712 billing questions
How is 34712 different from an aortic extension graft code?
34712 describes delivery of enhanced fixation devices to secure the endograft. An extension-graft code describes placement of an additional graft segment to extend or modify the repair.
Can 34712 be reported without an endovascular aortic repair?
The service is defined for delivery of fixation devices at the time of endovascular repair of an infrarenal aortic aneurysm or dissection. Document the associated repair and the device delivery.
Is imaging guidance separately included in this service?
Radiological supervision and interpretation associated with the fixation-device delivery are included when performed.
What documentation supports reporting 34712?
The operative report should identify the infrarenal aortic repair, the enhanced fixation-device delivery, and why the devices were used to secure the endograft.
How does the 90-day global period affect postoperative billing?
The day-before preoperative visit and 90 days of related postoperative care are included in the global period.
Can an assistant or co-surgeon be reported?
CMS permits assistant-at-surgery payment and co-surgeon reporting for this code. Team surgery is not permitted.
