What You Can Expect With Intraoperative Neurophysiological (IONM)

The Lead Up to Surgery

Your visit with a surgeon reveals the need for surgery coupled with use of neurophysiologic intraoperative monitoring services, and you receive a brochure explaining IONM services. The surgical booking staff at the surgeon’s office makes your appointment for surgery. IONM brochures and paperwork are sent to you before your procedure.

The surgeon’s office calls PAS and books IONM services for your surgery. A PAS surgical coordinator receives demographic and other pertinent information from the surgeon’s office. PAS confirms availability for the procedure. PAS then sends a packet of information to you which includes a PAS brochure and all necessary health insurance forms.

When you receive the information packet from PAS, you are asked to promptly complete the forms and return them. This is an important step as it establishes a proper flow for consent and arrangement for reimbursement by your health insurance carrier. Our administrative staff is happy to help you with completing the forms and can answer any questions you have related to our services. Please feel free to contact us at your convenience.

The Day of Surgery

The neurophysiologist arrives at the hospital well in advance of your scheduled surgical time and prepares all necessary equipment and electrodes. Before your surgery, the neurophysiologist will attempt to meet with you and your family and will take a brief medical history that includes the reason for surgery, the type of surgery and a description of current symptoms. A short physical examination is performed to establish pre-operative functionality.

The neurophysiologist meets with the surgeon and prepares a plan for monitoring. Electrodes will be applied to various sites of your body depending on the preferences of the surgeon and the type and site of surgery to be performed. Depending on the hospital’s protocol, additional electrodes may be applied once you enter the operating room.

Entering the Operating Room

The surgical team greets you, explains the process for anesthesia and outlines expectations before you go to sleep. The neurophysiologist obtains pre-operative baseline data, which will be stored and used as a guide throughout your procedure. Depending on the site of your procedure, a number of different electrophysiological tests may be employed throughout the operation.

All data acquired as your procedure progresses is communicated to the surgical team. Should changes occur, they are immediately reported to the surgeon to determine if a different course might achieve a better outcome. The goal of IONM is to report neurologic information that may improve your final disposition.

End of Surgery

Once your surgery is done, the neurophysiologist will remove the electrodes, and in many cases wait in the operating room with the rest of the surgical team for your awakening from anesthesia. Once that occurs, your surgeon will perform a short neurological examination before you’re taken to the recovery room.

Post Surgery

After your surgery, an IONM report is generated, an insurance claim form is completed, and an invoice is sent to your insurance carrier. We work very hard on your behalf to obtain the best reimbursement results. If you need reimbursement assistance, call our billing department at 484-351-8459; a collections specialist will answer all of your questions.


It is our heartfelt wish that you have a complete and speedy recovery.
