CPT® Code 93297

Interrogation device evaluation(s), (remote) up to 30 days; implantable cardiovascular physiologic monitor system, including analysis of 1 or more recorded physiologic cardiovascular data elements from all internal and external sensors, analysis, review(s) and report(s) by a physician or other qualified health care professional

The CPT® Code 93297 refers to the process of conducting remote interrogation evaluations of an implantable cardiovascular physiologic monitor system for a duration of up to 30 days. This procedure involves the analysis of one or more recorded physiologic cardiovascular data elements obtained from both internal and external sensors associated with the monitor. The primary objective of this evaluation is to provide comprehensive hemodynamic monitoring, which is essential for managing non-rhythm related cardiac conditions such as heart failure or unexplained syncope and collapse. The implantable cardiovascular physiologic monitor is designed to track various critical measurements, including intracardiac pressures—specifically right ventricular and left atrial pressures—as well as pulmonary artery pressure, the volume of water in the lungs, and the patient's body temperature. External sensors complement this monitoring by tracking physical activity, blood pressure, heart rate, and body weight. The interrogation of the physiologic monitor is performed remotely through telemetric communication, allowing healthcare professionals to access and analyze the data from a location separate from the patient. During this process, a physician or other qualified healthcare professional reviews the interrogated data to assess the device's functionality and the current programmed parameters. This includes a thorough examination of electrocardiogram recordings to identify any arrhythmias, as well as a review of stored data and events, which are compared with previous data acquisitions. The evaluation also encompasses the monitor's ability to sense and capture data accurately, along with an assessment of its mechanical function, including the integrity of the leads and battery. Any alerts generated by the device are carefully reviewed, and the patient is subsequently informed of the findings, culminating in the provision of a written report detailing the results of the evaluation.
