What 34813 covers

This add-on describes creating a graft connection between the femoral arteries during endovascular repair of an abdominal aortic aneurysm. It is commonly needed with an aorto-uni-iliac endograft: the device directs aortic flow into one iliac system, and the crossover graft carries blood to the opposite leg. A vascular surgeon performs the bypass as part of the operative repair, generally in a hospital or other facility setting.

Report 34813 only with the primary endovascular repair code when the femoral-femoral bypass is actually performed; it is not a stand-alone service. The operative report should establish the endograft configuration, the need for the crossover, and the graft connection between the femoral vessels. CMS treats this as an add-on billed with the primary procedure and paid within that procedure’s global period.

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

34808Iliac branch device
34808 concerns placement of an iliac occlusion device. Choose 34813 for the crossover bypass graft, not for occluding the opposite iliac artery.
34812Femoral exposure
34812 describes open femoral artery exposure for endograft delivery. It is not the femoral-to-femoral bypass graft reported with 34813.

34813 billing questions

When is 34813 appropriate with an endovascular aneurysm repair?

Use it when the repair includes construction of a femoral-to-femoral crossover graft, commonly to supply the opposite leg with an aorto-uni-iliac endograft. Do not report it for endograft placement alone.

Which primary procedure is commonly paired with 34813?

It is commonly paired with 34805 for an aorto-uni-iliac endovascular repair. Report the primary repair as well; 34813 cannot be billed by itself.

Can 34813 be reported for an iliac occlusion device alone?

No. An iliac occlusion device and a femoral-femoral bypass are different services; 34813 represents the bypass, not device placement.

What documentation supports reporting the bypass?

The operative report should describe the crossover graft, its femoral artery connections, and how it relates to the endovascular repair configuration.

Does 34813 have a separate global period?

CMS identifies it as an add-on paid within the primary procedure’s global period. Report it with the primary procedure rather than as a separate stand-alone service.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
