The procedure described by CPT® Code 0433T involves the repositioning of a neurostimulator system specifically for the treatment of central sleep apnea. Central sleep apnea is a condition characterized by the temporary cessation of breathing due to a lack of signals from the brain to the muscles responsible for respiration. This condition can be triggered by various factors, including strokes, certain medical conditions that affect the neck or brainstem, morbid obesity, and the use of narcotic medications. The neurostimulator system utilized in this procedure comprises an implantable pulse generator, a stimulation lead that is placed on the hypoglossal nerve (the twelfth cranial nerve), and a pressure sensing lead that is positioned within the chest. During the procedure, the focus is on repositioning the sensing lead only. To initiate the process, a surgical incision is made in the chest wall to gain access to the pulse generator. The pressure sensing lead is then disconnected from the generator. A specialized tool known as a subcutaneous tunneling tool is employed to navigate and free the sensing lead from its existing position. The lead is then carefully repositioned between the external and internal intercostal muscles to ensure optimal functionality. After repositioning, the sensing lead is reconnected to the pulse generator, followed by a testing phase to confirm proper operation. Finally, the incision is closed, completing the procedure.
