CPT® Code 95982

Electronic analysis of implanted neurostimulator pulse generator system (eg, rate, pulse amplitude and duration, configuration of wave form, battery status, electrode selectability, output modulation, cycling, impedance and patient measurements) gastric neurostimulator pulse generator/transmitter; subsequent, with reprogramming

The CPT® Code 95982 refers to the electronic analysis of an implanted gastric neurostimulator pulse generator and transmitter system. This procedure involves a detailed assessment of various parameters such as the rate, pulse amplitude and duration, configuration of the waveform, battery status, electrode selectability, output modulation, cycling, impedance, and patient measurements. Gastric electrical stimulation (GES) is a therapeutic approach used primarily to manage gastroparesis, a condition characterized by delayed gastric emptying. The GES system employs a gastric pacemaker device that delivers mild electrical stimulation to the lower stomach nerves, promoting contractions that facilitate the movement of food through the digestive tract. During the procedure, the gastric neurostimulator system is evaluated, particularly after its placement or replacement, which is reported separately. Prior to the insertion of electrodes into the stomach, the neurostimulator device and its memory card are programmed according to the specific needs of the patient. Following the placement of electrode wires, an interrogation procedure is conducted to ensure proper functionality. This involves attaching an interrogating head, checking the impedance between the wires, and making necessary adjustments if the impedance is not within the acceptable range. The process may require switching the polarity of the electrodes or adjusting the wires until the impedance is corrected. After the implantation procedure is completed, the interrogation and impedance analysis are repeated to confirm that the system is functioning correctly. The stimulation settings, including the stimulation rate, pulse width, cycling times, and battery status, are meticulously checked and documented. Once all components are verified to be operating properly, the device is activated, and the interrogating head is removed. This comprehensive analysis is crucial for ensuring the effective operation of the gastric neurostimulator system and is typically performed at regular intervals, such as every six months, to monitor the device's performance and make any necessary adjustments.
