CPT® Code 93153

The CPT® Code 93153 refers to the process of interrogating an implanted phrenic nerve stimulator system without making any programming changes. This procedure is specifically designed for patients who have previously undergone implantation of the phrenic nerve stimulator, which is utilized in the treatment of central sleep apnea. The interrogation process involves assessing the functionality and performance of the device to ensure it is operating effectively. During this procedure, various parameters are evaluated, including the rate of stimulation, pulse amplitude, duration, and timing of stimulation, as well as the impedance of the system. The interrogation is conducted while the patient is in different sleeping positions—supine, left side, and right side—to gather comprehensive data on the device's performance under varying conditions. Additionally, the battery status and electrode functionality are checked, along with patient compliance and output cycling. The patient's subjective feedback regarding the effectiveness of the current settings is also collected. It is important to note that while this code involves thorough assessment and data collection, it does not include any adjustments or reprogramming of the device settings, which distinguishes it from related codes that involve such modifications. The findings from the interrogation are then discussed with the patient, including any recommendations for future adjustments or monitoring that may be necessary.
