CPT® Code 0272T

Interrogation device evaluation (in person), carotid sinus baroreflex activation system, including telemetric iterative communication with the implantable device to monitor device diagnostics and programmed therapy values, with interpretation and report (eg, battery status, lead impedance, pulse amplitude, pulse width, therapy frequency, pathway mode, burst mode, therapy start/stop times each day);

The CPT® Code 0272T refers to an in-person interrogation device evaluation specifically for a carotid sinus baroreflex activation system. This procedure is essential for patients suffering from refractory hypertension, where the body's ability to regulate blood pressure and heart rate through the carotid sinus baroreflex is compromised. The implanted baroreflex activation device works by enhancing the electrical activity in the carotid baroreceptor afferent nerves, which the brain interprets as an increase in arterial blood pressure. In response, the central nervous system adjusts the sympathetic and vagus nerve outputs, leading to a reduction in both blood pressure and heart rate. The interrogation evaluation involves connecting the patient to an electrocardiogram (ECG) monitor and establishing a link between the implanted device and the interrogation device. This process allows for a thorough assessment of the device's functionality, including the review of device diagnostics and programmed therapy values. The physician analyzes the collected data to ensure the device is operating correctly and to identify any potential issues that may affect the patient's treatment. A comprehensive report detailing the findings is generated for the patient, ensuring they are informed about their device's performance and any necessary follow-up actions.
