About 34831: Open post-endovascular aortoiliac graft repair
Reports open conversion or repair of an infrarenal aortic aneurysm or dissection after endovascular repair, using a graft that extends to both iliac arteries.
This major open vascular operation repairs an infrarenal aortic aneurysm or dissection after prior endovascular aneurysm repair, using a bifurcated prosthetic graft with limbs extending to the iliac arteries. A vascular surgeon typically performs it in a hospital operating room when the aorta or prior endograft requires open surgical management. The graft configuration distinguishes this service from a tube graft or a graft extending to the femoral arteries.
Report the code when the operative record supports open repair following prior endovascular repair and documents the aorto-bi-iliac graft configuration. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate for this graft configuration. Assistant-at-surgery and co-surgeon payment may be allowed; team surgery payment is not permitted.

34831 billing questions
How does this differ from 34830 or 34832?
All three describe open repair following endovascular repair, but the graft endpoint differs: 34830 uses a tube graft, 34831 extends to both iliac arteries, and 34832 extends to the femoral arteries.
How does 34831 differ from 34802?
Both describe an aorto-bi-iliac graft configuration. Code 34831 is for open repair following prior endovascular repair; 34802 describes the corresponding open repair without that prior endovascular repair circumstance.
Should modifier 50 be appended?
No. The graft configuration is represented by the code, and modifier 50 is inappropriate.
What documentation supports code selection?
The operative report should establish the prior endovascular repair, the open repair performed, and the graft’s aortic and bilateral iliac endpoints.
How does the 90-day global affect postoperative billing?
The day-before preoperative visit and 90 days of related postoperative care are included in the global period.
Can an assistant surgeon or co-surgeon be reported?
CMS permits payment for an assistant at surgery and co-surgeons. Team surgery payment is not permitted.
