About 34812: Open femoral artery exposure for endograft delivery
Open femoral artery exposure provides groin access for delivery of an endovascular prosthesis during a qualifying aortic or iliac repair.
This service is an open exposure of a femoral artery through a groin incision to provide access for delivery of an endovascular prosthesis. It is typically performed by a vascular surgeon during endovascular aortic or iliac aneurysm repair when surgical exposure is needed instead of percutaneous access. The exposure supports passage of the endograft delivery system into the artery; it is not the endovascular repair itself.
Report 34812 only with an eligible primary procedure, such as endovascular repair of an infrarenal aortic aneurysm. The operative record should support the open femoral exposure and identify the side or sides and the role of the access in prosthesis delivery. CMS treats this as an add-on paid within the primary procedure’s global period. For bilateral exposure, CMS pays 150% when modifier 50 is reported.

34812 billing questions
When is 34812 reported instead of percutaneous access?

Can 34812 be billed by itself?
No. It is an add-on and must be reported with an eligible primary procedure involving endovascular prosthesis delivery.
How is bilateral femoral exposure reported?
Report modifier 50 for bilateral performance. CMS pays the code at 150% when modifier 50 is used.
What documentation supports 34812?
Document the open femoral artery exposure, the side or sides, and that the exposure provided access for delivery of the endovascular prosthesis.
How does 34812 differ from 34820?
34812 describes open femoral artery exposure through a groin incision. 34820 is used for open iliac artery exposure through a retroperitoneal incision.
