For patients

An extra layer of protection while you're asleep.

Your surgeon has asked us to monitor your nervous system during your operation. Here's what that means, what to expect and how billing works.

What is IONM?

Your nerves, checked continuously during surgery.

Intraoperative neurophysiological monitoring (IONM) uses small electrodes to send and record tiny electrical signals along your nerves, spinal cord and brain while you are under anesthesia.

A certified technologist watches those signals for the whole operation, with a physician reviewing them in real time. If a signal changes, the surgical team is told right away so they can adjust, often before any lasting injury happens. IONM is used in spine, brain, head and neck, blood vessel, and nerve surgeries.

What to expect

Before, during and after.

Before surgery

Meet your technologist

On the day of surgery a Delta technologist may introduce themselves, explain the monitoring and ask you to sign a consent and assignment-of-benefits form. Ask them anything.

During surgery

Monitoring while you sleep

Electrodes are placed after you are asleep, usually on your scalp, arms and legs. You won't feel the signals. We watch them for the entire operation.

After surgery

Little to notice

The electrodes are removed before you wake up. Some people notice minor redness, bruising or muscle soreness where they were placed, which usually fades within days.

Billing & insurance

How we bill for your care.

We bill your insurance directly, and we work to keep your share of the cost as low as the law and your plan allow.

Commercial insurance

We bill your plan

Delta is generally an out-of-network provider. We submit claims to your insurer on your behalf and, where needed, appeal for fair payment. Federal and New Jersey law protect you from most surprise bills at in-network facilities.

Auto accident

PIP / no-fault

If your surgery is related to a motor vehicle accident, we bill your auto carrier's personal injury protection coverage. Have your claim number and adjuster details ready.

Work injury

Workers' compensation

For work-related injuries, we bill your employer's workers' compensation carrier directly. Please share the claim number and case manager contact.

Questions

Frequently asked.

Why did my surgeon order neuromonitoring?

Some operations work close to the spinal cord, brain or important nerves. Monitoring gives your surgeon real-time information about how those structures are doing, so problems can be caught and corrected early.

Is IONM safe?

Yes. The risks are low. You may have minor bleeding, bruising or soreness where small electrodes were placed. When motor pathways are tested, there is a small risk of tongue or lip bites, which the team protects against with a soft bite block.

Will I feel anything?

No. Monitoring happens while you are under anesthesia, and the electrodes are removed before you wake up.

Who is watching my signals?

A CNIM-certified technologist stays with you in the operating room, and a licensed physician reviews the monitoring in real time from a secure connection.

Why did I get a separate bill from Delta?

Neuromonitoring is a separate professional service from your surgeon, anesthesiologist and hospital, so it is billed separately. If you have questions about a statement, call our billing team. We're happy to walk through it.

Do you take my insurance?

We bill commercial insurance plans, auto (PIP / no-fault) carriers and workers' compensation carriers. If you're unsure about your coverage, call us before your surgery and we'll help you check.
