CPT® Code 64582

Open implantation of hypoglossal nerve neurostimulator array, pulse generator, and distal respiratory sensor electrode or electrode array

The procedure described by CPT® Code 64582 involves the open implantation of a hypoglossal nerve neurostimulator array, a pulse generator, and a distal respiratory sensor electrode or electrode array. This surgical intervention is specifically designed to treat moderate to severe obstructive sleep apnea (OSA), a condition characterized by repeated episodes of airway obstruction during sleep, often caused by the relaxation of the tongue which can block the throat. The hypoglossal nerve stimulator functions by detecting the patient's breathing patterns and delivering a mild electrical pulse to the hypoglossal nerve, which in turn prompts the tongue to move forward, thereby maintaining an open airway and facilitating normal breathing during sleep. The device comprises several components: a pulse generator, which is compact and similar in size to a quarter, a breathing sensor that monitors respiratory activity, and a stimulation electrode that is strategically placed around the hypoglossal nerve. These components are interconnected through tunneled electrical leads, allowing for effective communication between the sensor and the stimulator. The entire system is designed to be user-friendly, with the patient able to control the stimulation remotely and program it according to their needs. The implantation procedure is typically performed on an outpatient basis under general anesthesia, ensuring that the patient is comfortable and pain-free during the operation.
