Official Description

Interrogation and programming (minimum one parameter) of implanted phrenic nerve stimulator system

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 93151 refers to the process of interrogation and programming of an implanted phrenic nerve stimulator system, specifically focusing on the adjustment of at least one parameter. This procedure is primarily utilized for patients who have undergone implantation of the phrenic nerve stimulator to treat central sleep apnea. The interrogation process involves assessing the device's performance and functionality, which includes evaluating the pulse generator in various sleeping positions—supine, left side, and right side. This assessment is crucial for determining the optimal settings for stimulation rate, pulse amplitude, duration, timing of stimulation, and impedance. During this procedure, healthcare professionals also check the battery status and the functionality of the electrodes, as well as measure output, cycling, and impedance. Patient compliance is another important factor that is evaluated. The patient's feedback regarding their experience with the device settings is gathered to ensure that the adjustments made align with their personal perceptions of efficacy. The data collected from the device is then used to configure the stimulation and pacing settings appropriately. In the context of CPT® Code 93151, at least one parameter must be modified or adjusted to enhance the therapeutic outcomes for the patient. This is distinct from CPT® Code 93153, which involves interrogation without any reprogramming or adjustments. Following the interrogation and programming, the results are communicated to the patient, including discussions about the necessity for any further adjustments and the importance of ongoing monitoring to ensure continued effectiveness of the treatment.

1. Indications

The procedure associated with CPT® Code 93151 is indicated for patients who have a previously implanted phrenic nerve stimulator system aimed at treating central sleep apnea. The specific indications for performing this interrogation and programming include:

  • Adjustment of Device Settings to address recent changes in efficacy or the emergence of new symptoms related to central sleep apnea.
  • Evaluation of Device Functionality to ensure that the pulse generator and electrodes are operating correctly and effectively.
  • Assessment of Patient Compliance to determine how well the patient is adhering to the treatment regimen and to gather feedback on their experience with the device.

2. Procedure

The procedure for CPT® Code 93151 involves several critical steps to ensure the effective interrogation and programming of the implanted phrenic nerve stimulator system. Each step is designed to gather comprehensive data and make necessary adjustments to optimize the device's performance.

  • Step 1: Interrogation of the Pulse Generator begins with the healthcare provider assessing the device while the patient is in different sleeping positions, including supine, left side, and right side. This is essential to determine how the device performs under various conditions and to identify any necessary adjustments to the stimulation parameters.
  • Step 2: Measurement of Parameters involves evaluating key metrics such as the rate of stimulation, pulse amplitude, duration, timing of stimulation, and impedance. These measurements are crucial for understanding the current functionality of the device and for making informed adjustments.
  • Step 3: Assessment of Battery and Electrode Functionality includes checking the battery status and ensuring that the electrodes are functioning properly. This step is vital to confirm that the device is capable of delivering the required stimulation effectively.
  • Step 4: Evaluation of Output and Cycling entails measuring the output and cycling of the device, which helps in understanding how well the device is performing and whether it meets the therapeutic needs of the patient.
  • Step 5: Gathering Patient Feedback is an integral part of the procedure, where the healthcare provider collects the patient’s input regarding their perception of the device settings and overall effectiveness. This feedback is essential for tailoring the device settings to the patient's needs.
  • Step 6: Adjustment of Parameters involves making changes to at least one parameter in the device programming based on the data collected and the patient’s feedback. This step is critical for achieving optimal therapeutic results.
  • Step 7: Discussion of Results concludes the procedure, where the healthcare provider discusses the findings of the interrogation and any adjustments made with the patient. This includes outlining the need for potential further adjustments and the importance of follow-up monitoring to ensure continued efficacy of the treatment.

3. Post-Procedure

After the interrogation and programming of the phrenic nerve stimulator system, patients are typically advised on the importance of follow-up appointments to monitor the effectiveness of the adjustments made. It is essential to assess the patient's response to the new settings and to determine if further modifications are necessary. Patients may also be instructed to report any new symptoms or changes in their condition promptly. Continuous monitoring and communication between the patient and healthcare provider are crucial for ensuring the long-term success of the treatment and for making any additional adjustments as needed.
