What 34812 covers

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.

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

34705Aortic endograft repair
34705 describes the primary endovascular aortic repair. Report 34812 as an add-on only when open femoral exposure is also performed for prosthesis delivery.
34820Iliac exposure
Use 34812 for open femoral artery exposure through a groin incision; 34820 describes open iliac artery exposure through a retroperitoneal incision.
34833Iliac access
34833 describes open iliac exposure with creation of a conduit. 34812 describes femoral exposure and does not represent conduit creation.

34812 billing questions

When is 34812 reported instead of percutaneous access?

Report it when the surgeon performs an open groin exposure of the femoral artery to deliver an endovascular prosthesis. Percutaneous arterial access alone does not describe this service.

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.
