Our mission is to protect what matters most — patients and their quality of life — by enhancing surgical safety through expert, real-time neuromonitoring. We are committed to clinical excellence and trusted collaboration with surgeons and hospitals, ensuring reliable insights and improved outcomes in every procedure.
Somatosensory Evoked Potentials (SSEP) are used to monitor the integrity of the sensory pathway of the spinal cord--specifically the dorsal columns. This is achieved by stimulating a peripheral nerve and recording the response with electrodes on the scalp over the primary sensory cortex. SSEP's may also be used to monitor other sensory structures at risk during surgery.
Transcranial Motor Evoked Potentials (TcMEP) are used to monitor the descending motor pathways of the lateral corticospinal tract and the corticobulbar tracts. This is achieved by stimulating the motor cortex and recording compound muscle action potentials (CMAP's) caudal to the surgical site. TcMEP's can also be used to monitor other motor structures at risk during surgery.
Spontaneous Electromyography (sEMG) is used to protect the cranial nerves and spinal nerve roots from injury due to excessive retraction, mechanical, thermal, and electrical irritation, or unintended dissection. This is achieved by monitoring the muscles innervated by these nerves.
Electroencephalography (EEG) is used intraoperatively to monitor the brain’s electrical activity and assess cerebral perfusion. By recording signals from electrodes placed on the scalp, EEG provides real-time information about cortical function and can detect changes associated with reduced blood flow (ischemia), such as during carotid endarterectomy procedures.
Brainstem Auditory Evoked Potentials (BAEPs) are used to monitor the integrity of the auditory pathways through the brainstem. This is achieved by delivering auditory stimuli through ear inserts and recording the neural responses with electrodes placed on the scalp. BAEPs provide real-time feedback on brainstem function and are particularly useful during procedures where the auditory nerve or brainstem structures are at risk.
Brain Mapping is used to identify and preserve critical functional areas of the brain—often referred to as “eloquent cortex”—including regions responsible for movement, sensation, and language. This is achieved through direct electrical stimulation of cortical and subcortical structures, allowing for real-time localization of essential pathways and helping guide safe tumor or lesion resection.
Your surgeon may use intraoperative neuromonitoring (IONM) during your procedure to help protect your brain, spinal cord, and nerves.
While you are asleep, a specialized technologist monitors your nervous system in real time. These signals help your surgical team understand how your nerves are functioning throughout the procedure.
You can think of neuromonitoring as a “voice” for your nervous system—alerting the team right away if any changes occur so they can respond and help keep you safe.
Before surgery, your technologist may meet you to introduce themselves and answer any questions. Once you are asleep, small electrodes are placed to monitor your nerve and muscle activity throughout the procedure.
During surgery, your technologist is present in the operating room and works closely with your surgical team. At the same time, a board-certified neurophysiologist monitors your signals remotely in real time, providing an additional layer of expertise.
All electrodes are removed before you wake up.
Neuromonitoring is a routine part of many procedures involving the spine, brain, and nerves. Our role is to support your surgeon by providing real-time information that helps guide safe surgical decisions.
EvokEd Neuromonitoring bills for services separately from the hospital and surgeon. In many cases, neuromonitoring services are processed as out-of-network by insurance plans.
We work directly with insurance companies on behalf of our patients and referring physicians, managing the billing process from start to finish. Our dedicated billing team submits claims, follows up with payers, and pursues appeals when necessary to ensure appropriate reimbursement for the services provided.
EvokEd Neuromonitoring does not balance bill.
Balance billing refers to charging a patient for the difference between the amount billed and the amount paid by insurance.
Patients are not billed for any remaining balance beyond what their insurance determines as standard cost-sharing (such as deductible, coinsurance, or copayment).
This approach is consistent with patient protection guidelines related to out-of-network services and surprise billing.
After your procedure, you may receive an Explanation of Benefits (EOB) from your insurance company.
An EOB is not a bill. It is a summary of how your insurance processed your claim.
The EOB may list a physician you do not recognize. This is the physician who supervised your neuromonitoring during surgery and was part of your care team, even though you may not have met them in person.
Insurance companies may also list a higher “patient responsibility” amount on the EOB. This amount is determined by the insurance company and does not reflect what you will be billed by our team.
If there is any patient responsibility after your claim has been fully processed, you may receive a statement from our billing team.
We understand that medical billing can feel confusing. Our team is here to provide clarity, answer questions, and guide you through the process.
We’re proud to be part of your care and are committed to supporting you every step of the way.
