CPT® Code 93152

The CPT® Code 93152 refers to the process of interrogating and programming an implanted phrenic nerve stimulator system during a polysomnography, which is a comprehensive sleep study. This procedure is specifically designed for patients who have a phrenic nerve stimulator implanted to treat central sleep apnea. The interrogation involves assessing the functionality of the stimulator, which is a device that helps regulate breathing by stimulating the diaphragm. During the sleep study, a healthcare professional, typically a programmer, continuously evaluates the device's performance while the patient sleeps in various positions: on their back, right side, and left side. This multi-positional assessment is crucial as it allows for the collection of data on how the stimulator performs under different conditions, which can affect the patient's breathing patterns. The programming aspect involves making necessary adjustments to the neurostimulator's parameters based on the data collected, aiming to optimize the patient's respiratory rate, pulse amplitude, duration, and the threshold at which the patient may awaken due to breathing disturbances. The adjustments are tailored to ensure that the patient experiences the least number of apneic events during sleep, thereby improving overall sleep quality and respiratory function. After the interrogation and programming, the results are thoroughly discussed with the patient, including any further adjustments that may be needed and the importance of follow-up monitoring to ensure the continued efficacy of the treatment.
