Spinal Monitoring Services

The Human Nervous System
We strive to provide the most up to date and safest procedures for all our patients. In order to attain this goal, we use a procedure known as Intraoperative Neuromonitoring (IONM) during the course of your surgery. IONM is a set of procedures that will monitor the functional integrity of the spinal cord and peripheral nerves during the course of the surgery. The information obtained from the IONM procedures will be communicated to your surgeon and other members of the surgical team in real time in order to provide the safest outcomes possible for your procedure. IONM has been used in orthopedic spine and neurosurgery for more than 20 years and is shown to help reduce the risk of negative surgical outcomes such as paralysis, numbness, weakness, or stroke. IONM of the spinal cord and nerve roots during spine surgery is deemed medically necessary by our surgeons and is considered the standard of care in our community.

Sentinel Neuromonitoring will be the provider of IONM services, and IONM professionals from Sentinel Neuromonitoring will be present during your entire procedure. Professional Oversight Consultants provides remote professional oversight and assistance, which is required by the medical facility when IONM is used. Sentinel Neuromonitoring and Professional Oversight Consultants, like all local neuromonitoring companies, are not in network providers with any insurance company. We will bill your insurance company for our services and if you are left with a balance after any insurance payments, you will be billed for the difference. Please note this does not apply to workman’s comp or Medicare/Medicaid patients..

Please follow the links below for the forms that will allow us to appeal any insurance payment denials on your behalf. Signing these forms simplifies the insurance appeals process for you, and will help to minimize the time spent by you dealing with insurance claims.

BC/BS patients, please sign and return the forms specific to BC/BS, these are required by your insurer. Not signing these forms may delay or cancel your procedure.

All other patients please sign and return the general consent for appeal approval form.

If you have any questions regarding how Intraoperative Monitoring will be used during your surgery please discuss it with your physician, or contact our office manager and a technician will call you to explain how we will contribute to the safety of your procedure.

More general information about neurodiagnostics can be found below.


Neurodiagnostics analyzes and monitors nervous system function to promote the effective treatment of neurological diseases and conditions. Technologists record electrical activity arising from the brain, spinal cord, and peripheral nerves using a variety of techniques and instruments. Physicians and other specialists then use this information to determine the best course of treatment for individual patients.

Evoked Potentials (EP) – Record Electrical Activity in Response to Stimulation

Evoked Potentials (EP) are recordings of electrical activity from the brain, spinal nerves, or sensory receptors in response to specific external stimulation. Evoked potentials are helpful in evaluating a number of different neurological problems, including spinal cord injuries, injuries to peripheral nerves and nerve roots, and vascular insults to the nervous system. This test is commonly performed by the technologist during surgery on the spine to help the surgeon make sure nerves are not damaged during the operation. EP can also be performed in a clinical neurodiagnostic laboratory.

Intraoperative Neuromonitoring (IONM) – Monitors Nervous System During Surgery

IONM is the use of neurophysiological monitoring techniques during surgery to provide information to the surgeon about nervous system integrity in real time. IONM is a subspecialty of Evoked Potentials and uses supplementary testing procedures specific to spine surgery and neurosurgery. The use of IONM guards against neurological complications during surgery and helps reduce the risk of negative surgical outcomes such as paralysis, numbness, weakness, or stroke.
