What 34704 covers
This service treats a rupture involving the infrarenal abdominal aorta and an iliac artery by placing an endograft that directs blood through one iliac route while excluding the affected area. Vascular surgeons typically perform the repair urgently in a hospital operating or hybrid suite, using imaging to guide graft placement. The service includes associated radiological supervision and interpretation and extensions when performed.
Report 34704 when the operative record supports both the ruptured condition and the aorto-uni-iliac graft configuration; document the treated anatomy, rupture, and repair performed. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. 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 may be made and co-surgeons are permitted; team-surgery payment is not permitted.

How to choose
- 34703Aortic endograft repairOne iliac artery
- This uses the same aorto-uni-iliac graft configuration, but is for repair without rupture. The rupture status documented in the operative record distinguishes the codes.
- 34706Aortic endograft repairRupture, bilateral iliac limbs
- Both address rupture, but 34706 describes a bifurcated aorto-bi-iliac graft configuration rather than an aorto-uni-iliac configuration.
- 34702Aortic endograft repairRupture, aorto-aortic tube
- Both address rupture, but 34702 uses an aorto-aortic tube graft configuration rather than extending the repair into one iliac route.
34704 billing questions
How does 34704 differ from 34703?
Both describe an aorto-uni-iliac endograft repair. Use 34704 for a ruptured aneurysm and 34703 for the corresponding repair without rupture.
Which graft configuration supports 34704?
The repair uses an aorto-uni-iliac configuration, routing flow through one iliac artery. A bifurcated graft configuration points to a different code.
Are imaging guidance and interpretation separately reported?
The associated radiological supervision and interpretation are included in 34704. The code also includes extensions when performed.
What documentation supports reporting 34704?
The operative report should identify the rupture, infrarenal aortic and iliac anatomy treated, and the aorto-uni-iliac graft configuration used.
How does the 90-day global period affect postoperative care?
The day-before preoperative visit and 90 days of related postoperative care are included in the global period.
