CPT® Code 0435T

Deleted

The CPT® Code 0435T refers to the programming device evaluation of an implanted neurostimulator pulse generator system specifically designed for the treatment of central sleep apnea. This procedure involves the interrogation and programming of the neurostimulator system, which is typically performed approximately one month following the surgical implantation of the device. During this evaluation, the healthcare provider assesses the algorithm that monitors the patient's breathing patterns and adjusts the system to deliver hypoglossal nerve stimulation at the most critical moment of respiration—the inspiratory phase—when the airway is particularly susceptible to collapse. The programming device is utilized to establish the upper and lower limits of pulse stimulation, as well as to set parameters for the rate and duration of stimulation. Additionally, the patient receives instructions on how to operate a home remote, which allows them to adjust the intensity of the stimulation pulses within the parameters predetermined by the physician during the programming session. This code specifically captures a single session of programming device evaluation, which is essential for ensuring the optimal functioning of the neurostimulator system. It is important to note that programming may also occur during a sleep study encounter, as indicated by CPT® Code 0436T, to fine-tune various operational parameters of the device. For the assessment of the neurostimulator system's performance, including rate, amplitude, duration, and intensity of stimulation, as well as battery status and patient compliance, CPT® Code 0434T should be reported for interrogation purposes.
