What 34833 covers

A vascular surgeon exposes an iliac artery through an abdominal incision to provide access for an endovascular prosthesis. When the artery cannot safely accommodate the delivery system directly, the surgeon may create a conduit to connect the vessel with the access route. This work is typically performed in the operating room during endovascular aortic or iliac repair, rather than as a separate access operation.

Report 34833 only with an eligible primary procedure; it is an add-on and is paid within that procedure’s global period. The operative report should identify the side, the iliac exposure, the purpose of access, and whether a conduit was created. Do not select this code for femoral or brachial exposure, or for iliac exposure without the conduit-related work that distinguishes it from 34820. For bilateral service, modifier 50 is paid at 150%.

How to choose

34820Iliac exposure
Both involve open iliac exposure, but 34833 is the access service distinguished by conduit creation when performed for endovascular delivery. 34820 describes iliac exposure without that distinction.
34812Femoral exposure
Use 34812 for open femoral access through a groin incision. 34833 is for iliac access through an abdominal incision.
34834Arterial exposure
34834 describes open brachial access. Choose 34833 when the open access site is the iliac artery.

34833 billing questions

How does 34833 differ from 34820?

34833 describes abdominal iliac access for endovascular device delivery with conduit creation when performed. Use 34820 for iliac exposure that does not include the conduit-related service described by 34833.

Can 34833 be reported by itself?

No. It is an add-on code and must be reported with an eligible primary procedure.

Is conduit creation separately reported?

Conduit creation, when performed as part of this iliac access service, is included in 34833. Document the conduit and its role in device delivery in the operative report.

How is bilateral iliac access reported?

CMS pays the bilateral procedure with modifier 50 at 150%. Document the work on both sides.

What documentation supports 34833?

The operative report should identify the abdominal approach, iliac artery accessed, reason open access was needed for endovascular delivery, and whether a conduit was created.
