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.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

How to choose

34703Aortic endograft repair
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 repair
Both address rupture, but 34706 describes a bifurcated aorto-bi-iliac graft configuration rather than an aorto-uni-iliac configuration.
34702Aortic endograft repair
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.
