Official Description

Interrogation device evaluation (in person) with analysis, review and report, includes connection, recording and disconnection per patient encounter, implantable cardiac contractility modulation system

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

An interrogation device evaluation is a critical procedure performed in the management of patients with an implantable cardiac contractility modulation (CCM) system. This evaluation is conducted in person by a physician or qualified healthcare professional to ensure the proper functioning of the device and to optimize its programmed settings for each patient. The CCM system is designed to enhance cardiac contractility, which can be particularly beneficial for patients with heart failure. During the evaluation, the healthcare provider connects the CCM device to a programming unit wirelessly. This connection allows for the recording of stimulation signals emitted by the pulse generator, which are essential for assessing the device's performance. After the data is recorded, the programming unit is disconnected from the patient. The procedure culminates in a comprehensive analysis and review of the recorded data, leading to a detailed written report that outlines the findings and any necessary adjustments to the device settings. This process is vital for ongoing patient management and ensuring optimal therapeutic outcomes.

1. Indications

The interrogation device evaluation using CPT® Code 0418T is indicated for patients who have an implantable cardiac contractility modulation (CCM) system. This procedure is performed to monitor the functionality of the device and to ensure that the programmed values are optimized for the patient's specific cardiac needs. The evaluation is essential for patients experiencing heart failure or other related cardiac conditions where the CCM system is utilized to improve heart function.

  • Heart Failure Management This procedure is indicated for patients with heart failure who require ongoing assessment of their implantable CCM system to ensure effective treatment.
  • Device Function Monitoring The evaluation is necessary to monitor the performance of the CCM device, ensuring it operates correctly and delivers appropriate stimulation to the heart.
  • Optimization of Programmed Values The procedure allows healthcare professionals to select and adjust the optimal programmed values for the CCM system, enhancing patient outcomes.

2. Procedure

The interrogation device evaluation procedure involves several key steps to ensure a thorough assessment of the implantable cardiac contractility modulation system. Each step is crucial for the accurate monitoring and optimization of the device.

  • Step 1: Connection The healthcare provider begins by establishing a wireless connection between the CCM device implanted in the patient and a programming unit. This connection is essential for the subsequent data recording process.
  • Step 2: Recording Once connected, the programming unit records the stimulation signals generated by the pulse generator of the CCM system. This data collection is vital for evaluating the device's performance and effectiveness in stimulating cardiac contractility.
  • Step 3: Disconnection After the data has been successfully recorded, the programming unit is then disconnected from the patient. This step concludes the direct interaction with the device, allowing for the analysis of the recorded information.
  • Step 4: Analysis and Review Following disconnection, the healthcare provider conducts a detailed analysis and review of the recorded data. This step is critical for identifying any necessary adjustments to the device settings based on the patient's current condition.
  • Step 5: Reporting Finally, a written report is generated that summarizes the findings from the evaluation. This report includes insights from the analysis and any recommendations for changes to the device programming, ensuring that the patient receives optimal care.

3. Post-Procedure

After the interrogation device evaluation is completed, the patient may be monitored for any immediate reactions or complications related to the procedure. Typically, there are no significant post-procedure care requirements, as the evaluation is non-invasive and does not involve any surgical intervention. However, the healthcare provider may discuss the findings from the evaluation with the patient, including any adjustments made to the CCM system's programming. Follow-up appointments may be scheduled to reassess the device's performance and the patient's response to any changes made. Continuous monitoring and periodic evaluations are essential for maintaining the effectiveness of the CCM system in managing the patient's heart condition.

59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
