Neurophysiology monitoring
About G0453: Remote continuous intraoperative neuromonitoring
Reports continuous neurophysiologic monitoring during surgery when the monitoring professional observes the patient from outside the operating room, including a remote location.
G0453 covers real-time neurophysiologic monitoring during an operation when the monitoring professional is outside the operating room, such as at a remote workstation. The professional observes patient-specific signals during surgery and communicates clinically significant changes to the operating team. It is used for procedures in which ongoing monitoring can help the surgical team identify changes in neural function, including some spine and brain operations.
Report the service by patient and in 15-minute units, based on the time spent providing continuous monitoring. The record should identify the operation, monitoring professional, signals followed, monitoring start and stop times, significant signal changes, and communications with the surgical team. CMS assigns work, practice-expense, and malpractice relative value units to the service. The supplied CMS payment rules list no additional payment adjustments for this code.
