CPT® Code 34712

Transcatheter delivery of enhanced fixation device(s) to the endograft (eg, anchor, screw, tack) and all associated radiological supervision and interpretation

The CPT® Code 34712 refers to the transcatheter delivery of enhanced fixation devices to an endograft, which may include anchors, screws, tacks, or staples. This procedure is essential in situations where there is a risk of migration or dislocation of the stent graft, as well as the potential occurrence of endoleaks. Such risks may arise due to increased forces acting on the endograft. The procedure begins with accessing the femoral artery, which can be achieved either through a small skin incision or via a percutaneous needle puncture. Utilizing fluoroscopic guidance, a fixation device is advanced to the endograft through a deflatable guide sheath and an electromechanical delivery device. The fixation device, which is typically made of a metal alloy, is then deployed into the landing zone of the stent graft, ensuring that it does not penetrate the adventitia layer of the vessel wall. To ensure adequate security of the endograft, a minimum of four to six fixation devices are utilized. Following the placement of these devices, angiography is performed to verify the correct positioning of the endograft and to check for any endoleaks that may need to be addressed. Finally, the catheter guide sheath and delivery device are withdrawn, and the skin incision is closed, completing the procedure.
