Effective Date: N/A Surgery - Surgical Procedures on the Nervous System Feed
Removal of hypoglossal nerve neurostimulator array, pulse generator, and distal respiratory sensor electrode or electrode array.
Modifier 52 may be used to indicate reduced services if only part of the system is removed.
Medical necessity for removal should be clearly documented. This may include device malfunction, infection, patient intolerance, or the patient's decision to discontinue therapy.
The surgeon makes incisions to access the hypoglossal nerve and the implanted components of the neurostimulator system. They carefully remove the electrode array from around the hypoglossal nerve, the distal respiratory sensor, the leads connecting these components to the pulse generator, and the pulse generator itself. The incisions are then closed.
In simple words: The doctor removes a device implanted under your skin that helps you breathe better during sleep. This device stimulates the nerve that controls your tongue to keep your airway open. The removal procedure involves taking out the parts of the device that sense your breathing, send signals, and stimulate the nerve.
Removal of a previously implanted hypoglossal nerve neurostimulator system, including the electrode array, pulse generator, and distal respiratory sensor electrode or electrode array. This procedure is typically performed to remove the entire system used to treat obstructive sleep apnea (OSA). The hypoglossal nerve controls tongue movement, and stimulation of this nerve helps keep the airway open during sleep. The distal respiratory sensor monitors breathing patterns, and the pulse generator sends signals to the hypoglossal nerve based on the respiratory sensor input.
Example 1: A patient who has had a hypoglossal nerve stimulator for several years experiences device malfunction and requires removal of the entire system., A patient with a hypoglossal nerve stimulator develops an infection at the implant site, necessitating removal of the device., A patient decides to discontinue therapy with their hypoglossal nerve stimulator and undergoes removal of the device.
Documentation should include the reason for removal, surgical approach, intraoperative findings, any complications encountered, and confirmation of removal of all system components.
