CPT® Code 0429T

Deleted

The procedure described by CPT® Code 0429T involves the removal 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 the brain's failure to signal the muscles responsible for respiration. This condition can be triggered by various factors, including stroke, anatomical issues affecting the neck or brainstem, morbid obesity, and the use of narcotic medications. The neurostimulator system utilized in this treatment comprises an implantable pulse generator, a stimulation lead that interfaces with the hypoglossal nerve (the twelfth cranial nerve), and a pressure sensing lead that is positioned in the chest. During the removal procedure, the focus is on extracting the sensing lead only. The process begins with the identification of the pulse generator's location, followed by an incision made in the chest wall to access the device, which is situated in a pocket just above the pectoralis major muscle. The procedure entails disconnecting the pressure sensing lead from the pulse generator, utilizing a subcutaneous tunneling tool to carefully free the lead from its anatomical position between the external and internal intercostal muscles, and subsequently removing it. After the lead is successfully extracted, the incision is closed. This procedure is critical for patients who may no longer require the neurostimulator system or who are experiencing complications related to the device.
