About 34820: Open Iliac Access for Endograft Delivery
Reports open iliac artery exposure through an abdominal or retroperitoneal incision when needed to deliver an endovascular prosthesis during a qualifying repair.
A vascular surgeon or other qualified surgeon uses an abdominal or retroperitoneal incision to expose an iliac artery so an endovascular prosthesis can be delivered through that access. This is an open access procedure, distinct from gaining access through a groin incision to expose the femoral artery. Code 34820 describes exposure without the conduit creation identified by code 34833.
Report 34820 only as an add-on with a qualifying primary procedure, such as an endovascular aortic repair; it is not a stand-alone service. The operative report should identify the iliac artery exposed, the open approach, and its role in delivering the prosthesis. CMS places the add-on service within the primary procedure’s global period. For bilateral exposure, modifier 50 is paid at 150% under the stated CMS rule.

34820 billing questions
When should 34820 be chosen instead of 34812?
Use 34820 for open iliac artery exposure through an abdominal or retroperitoneal incision. Code 34812 describes open femoral artery exposure through a groin approach.
How does 34820 differ from 34833?
Code 34820 describes open iliac exposure for prosthesis delivery without conduit creation. Code 34833 is the related option when a conduit is created.
Can 34820 be billed by itself?
No. CMS identifies it as an add-on code, so it must be reported with a qualifying primary procedure.
How is bilateral iliac exposure reported?
When the procedure is bilateral, report modifier 50. CMS pays the bilateral service at 150%.
What should the operative note support?
Document the side and artery exposed, the abdominal or retroperitoneal approach, and that the exposure provided access for endovascular prosthesis delivery.
