About 34830: Open aortic repair with tube graft
Open conversion of a previously endovascularly treated aorta with replacement using a straight tube graft is reported when the operative repair uses that graft configuration.
This service covers open reconstruction of an aortic segment using a straight tube prosthesis after prior endovascular repair. A vascular surgeon performs the operation in a hospital operating room, exposing the aorta and replacing or reconstructing the affected segment. The procedure may involve addressing the existing endograft as part of the open repair; report this code when the documented reconstruction uses a tube graft rather than an aortoiliac or aortofemoral configuration.
Select the code from the operative report’s description of the prior endovascular repair, the open reconstruction, and the prosthesis configuration. Documentation should support why open repair was needed and identify the graft used. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed 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. An assistant at surgery may be paid, and co-surgeons are permitted; team surgery is not permitted.

34830 billing questions
When is 34830 selected instead of 34831 or 34832?
Select 34830 when the open reconstruction after endovascular repair uses a straight tube graft. Codes 34831 and 34832 distinguish aortoiliac and aortofemoral graft configurations.
How does 34830 differ from 35081?
34830 applies to open aortic reconstruction following endovascular repair, with a tube prosthesis. 35081 describes a different open abdominal aortic aneurysm repair service; use the code supported by the operative circumstances and procedure performed.
Can an assistant surgeon or co-surgeon be reported?
CMS permits payment for an assistant at surgery and permits co-surgeons for 34830. Team surgery is not permitted.
Does modifier 50 apply to this procedure?
No. CMS identifies bilateral adjustment as inappropriate for this code.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
How are other procedures in the same session paid?
The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple-procedure reduction.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
