CPT® Code 95940

Add-On Code

Continuous intraoperative neurophysiology monitoring in the operating room, one on one monitoring requiring personal attendance, each 15 minutes (List separately in addition to code for primary procedure)

Continuous intraoperative neurophysiology monitoring is a critical procedure performed during surgical operations to ensure the safety and integrity of the nervous system. This monitoring involves the ongoing assessment of electrophysiological signals, specifically sensory evoked potentials and electromyography (EMG) potentials, throughout the duration of the surgical procedure. The primary goal of this monitoring is to detect any potential neurological deficits that may arise during surgery, thereby minimizing the risk of permanent postoperative complications. The CPT® Code 95940 is specifically designated for instances where one-on-one monitoring is conducted, requiring the personal attendance of a qualified neurophysiologist or technician. This code is billed for each 15-minute interval of monitoring, and it is important to note that it should be reported separately in addition to the code for the primary surgical procedure being performed. This ensures that the additional resources and expertise required for continuous monitoring are appropriately recognized and reimbursed. In contrast, for cases involving multiple patients or procedures being monitored simultaneously, CPT® Code 95941 is utilized, which accounts for continuous monitoring on an hourly basis. Understanding the nuances of these codes is essential for accurate billing and compliance in the context of intraoperative neurophysiology monitoring.
