IONM Process



Intraoperative neurophysiologic monitoring can help prevent and reduce accidental nerve damage during complex surgeries that place the brain, cranial nerves, spinal cord, and peripheral nerves at risk of injury.

During IONM, electrodes are placed on a patient’s skin near nerves. Small electrical currents then are used to trigger nerve impulses that follow their natural pathways to and from the brain and spinal cord. The impulses are first measured after the patient is anesthetized for surgery, and then are compared to measurements taken during surgery.

Changes in nerve impulses can be an early sign of nerve injury, so if they are detected, the IONM clinician alerts the surgeon and they work together with the neurologist to find the cause before permanent damage can occur.


Our professional monitoring program sends your insurance company a standard bill for intraoperative monitoring services. This monitoring service is separate from the services from your hospital and surgeon.

We periodically review billing regulations to ensure compliance with the law, and communicate with clients to notify them of changes in billing. Please contact us if you have questions or concerns about your intraoperative monitoring bill.
