The CPT® Code 0302T refers to the procedure involving the insertion, removal, and replacement of a complete intracardiac ischemia monitoring system. This system is designed to monitor electrocardiogram (ECG) changes, specifically focusing on ST segment alterations, in real time. It serves a critical function by alerting patients to seek immediate medical attention when a cardiac ischemic event is detected, which is particularly vital for individuals who may not experience or recognize typical warning signs such as chest pain, shortness of breath, nausea, or diaphoresis (sweating). The monitoring device is composed of several components, including a programmable implantable monitoring device (IMD), a right ventricular lead wire, a lead wire adapter, an external alarm device (EXD), and a programming unit. The procedure for inserting the device typically occurs in a cardiac catheterization lab under monitored anesthesia care (MAC) or moderate sedation. The physician administers a local anesthetic to the upper left chest area and makes a small incision, approximately 2-3 inches long. Utilizing fluoroscopy, the lead wire is carefully advanced through a vein to reach the apex of the right ventricle, where it is connected to the IMD. The IMD is then programmed, inserted into the chest incision, and tested before the skin is sutured closed. The EXD is designed to activate an alarm—through vibration, flashing lights, or audible beeps—when the device detects that a ten-second ECG reading falls outside the established baseline, prompting the patient to seek urgent medical care. The data collected by the device can be retrieved and analyzed by the treating physician, making it a valuable tool for patients at high risk for ischemic cardiac events, such as those with a history of acute coronary events, diabetes, or renal insufficiency.

The intracardiac ischemia monitoring system is indicated for use in patients who are at high risk for ischemic cardiac events. This includes individuals with the following conditions:
The procedure for the insertion, removal, and replacement of the intracardiac ischemia monitoring system involves several critical steps:
Post-procedure care involves monitoring the patient for any immediate complications related to the incision site and ensuring the proper functioning of the intracardiac ischemia monitoring system. Patients are typically advised to follow up with their healthcare provider for device interrogation and programming adjustments as needed. The external alarm device (EXD) should be tested to confirm its operational status, and patients should be educated on recognizing alarm signals and the importance of seeking emergent medical care when alerted. Regular follow-up appointments are essential for data retrieval and analysis by the treating physician to assess the patient's cardiac status and adjust treatment plans accordingly.
