Deep brain stimulation (DBS) is a neurosurgical procedure that involves the implantation of electrodes within specific areas of the brain to treat various neurological conditions. This technique is particularly effective for managing symptoms associated with Parkinson's disease, essential tremor, and dystonia. The procedure entails placing stimulating electrodes in targeted brain regions, which are then connected to a pulse generator. This generator is typically implanted in a subcutaneous pocket located in the supraclavicular region of the body. The pulse generator is programmed by a physician to deliver electrical impulses that help alleviate the symptoms of the neurological disorder being treated. As the conditions may progress or change over time, the pulse generator requires periodic reprogramming to ensure optimal therapeutic benefits. During the initial programming or any subsequent reprogramming sessions, the physician first assesses the overall functionality of the deep brain stimulation system. After confirming that the system is operating correctly, the physician interrogates the device to gather data on its usage, especially if it is a reprogramming session. The physician also engages with the patient to discuss their experiences with the device since the last adjustment, addressing any issues or concerns that may have arisen. Additionally, the physician reviews any medications the patient is taking in conjunction with the device to determine if any modifications are necessary. Based on this comprehensive evaluation, the physician sets the programming parameters for the initial programming or reviews the existing settings during reprogramming. These parameters include the rate, amplitude, duration of stimulation, battery status, electrode selectability and polarity, and impedance. The physician then proceeds to program or reprogram the deep brain neurostimulator device. For billing purposes, the CPT® code 95978 is used for the first hour of initial programming or subsequent reprogramming, while CPT® code 95979 is designated for each additional 30 minutes of programming or reprogramming beyond the first hour.
