CPT® Code 34812

Add-On Code

Open femoral artery exposure for delivery of endovascular prosthesis, by groin incision, unilateral (List separately in addition to code for primary procedure)

The procedure described by CPT® Code 34812 involves the surgical exposure of the femoral artery to facilitate the delivery of an endovascular prosthesis. This is achieved through a unilateral groin incision, which means that the incision is made on one side of the groin area. The process begins with an incision through the skin over the groin, followed by careful dissection of the subcutaneous tissue to reach the common femoral artery. During this dissection, it is crucial to protect the surrounding structures, particularly the femoral nerve and vein, to prevent any potential complications. Once the common femoral artery is accessed, the surgeon also dissects the superficial and deep femoral arteries, ensuring they are free from surrounding tissue and can be manipulated as needed. Vessel loops are used to capture these arteries for better visibility and access. In some cases, the distal external iliac artery may also be dissected, which may require the retraction or division of the inguinal ligament to gain adequate access. Additionally, any small branch arteries encountered during the procedure are typically ligated or cauterized to minimize bleeding. The femoral artery is then clamped and incised, allowing for the introduction of guide wires and sheaths necessary for the subsequent placement of the endovascular device. It is important to note that this procedure is reported separately and in conjunction with a primary procedure, highlighting its role as a preparatory step in the overall endovascular intervention.
