CPT® Code 64583

Revision or replacement of hypoglossal nerve neurostimulator array and distal respiratory sensor electrode or electrode array, including connection to existing pulse generator

The procedure described by CPT® Code 64583 involves the revision or replacement of a hypoglossal nerve neurostimulator array and distal respiratory sensor electrode or electrode array. This procedure is essential for patients who have previously undergone the implantation of a hypoglossal nerve stimulator, which is a device designed to treat moderate to severe obstructive sleep apnea (OSA). OSA is a condition characterized by repeated episodes of airway obstruction during sleep, often caused by the relaxation of the tongue, which can block the airway. The hypoglossal nerve stimulator works by delivering electrical pulses to the hypoglossal nerve, prompting the tongue to move forward and thereby keeping the airway open during sleep. The device consists of several components, including a pulse generator, a breathing sensor, and a stimulation electrode that is placed around the hypoglossal nerve. These components are interconnected by tunneled electrical leads, allowing for the remote control and programmability of the stimulator. Patients typically activate the device before sleep to ensure proper function throughout the night. In cases where the neurostimulator array or the distal respiratory sensor experiences issues such as malfunction or infection, a surgical intervention may be necessary to revise or replace these components. This procedure ensures that the device continues to function effectively, maintaining its role in managing obstructive sleep apnea. The revision or replacement is performed while keeping the existing pulse generator intact, which can help reduce recovery time and surgical risks associated with complete device removal.
