An EEG records the electrical activity of your brain through electrodes taped to your scalp. Nothing is injected, nothing is radioactive, and the equipment is cheap compared with an MRI scanner. Yet the price you are quoted can swing more than three to one for the identical 30-minute test, and a large share of people who get one end up with two separate bills for it.

That happens because an EEG is really two products sold together: the recording (equipment, electrodes and a technologist) and the reading (a neurologist interpreting the tracing). Where you have the recording done, and whether the reading is bundled into your quote, drives almost the entire price. This guide uses the 2026 CMS payment files as a floor, real prepaid cash prices, and a hospital’s own published charge list to show what each version of the test actually costs.

The low column for the routine EEG is Medicare’s 2026 hospital outpatient payment. Under the July 2026 OPPS Addendum B, CPT 95816 (awake and drowsy), 95819 (awake and asleep) and 95822 (coma or sleep only) all sit in APC 5722 and pay the facility $220.60, with a $44.12 patient coinsurance. The average column is the flat cash rate posted by the Center for Neurology and Spine in Phoenix, which charges $500 for an EEG whether it is awake, drowsy or asleep. The high column is Avita Health System’s published charge for CPT 95816, $1,180 as of July 1, 2026, which Avita states is “before insurance or discount” and does not include the interpreting provider.

The prepaid market sits between those poles. On MDsave, read September 3, 2026, an EEG (awake and asleep) ranges from $366 to $794 nationally and a seizure sleep-deprived EEG test ranges from $366 to $790. The $578 in the average column above is the midpoint of that published national band, not a separately reported average. Notice how close the two products are: sleep deprivation is an instruction you follow the night before, not extra hardware.

The long-recording rows are arithmetic on 2026 Medicare rates, since almost nobody publishes a cash price for these. A 24-hour ambulatory study is the setup code 95700 ($220.60) plus one 12-to-26-hour recording block 95708 ($381.24) plus the physician read 95719 ($165.00), which totals $766.84. A 72-hour study is $220.60 plus three blocks at $381.24 plus the longer read code 95723 ($264.54), which totals $1,628.86. A day of video EEG is 95716 ($877.34 under APC 5724) plus the physician code 95720 ($212.10), which totals $1,089.44.

What Drives the Price

The setting, more than anything else

The same routine EEG pays $220.60 to a hospital outpatient department under OPPS and $482.31 as a global service under the 2026 Physician Fee Schedule when a freestanding office does the whole thing (CPT 95819, 14.44 RVUs at the $33.4009 conversion factor). A hospital’s own list charge for the technical side alone can be $1,180. Independent diagnostic testing facilities and neurology offices are usually the cheapest route for a routine study because there is no facility fee stacked on top.

The technical and professional split

This is the mechanic behind the two-bill problem. Modifier TC covers the recording; modifier 26 covers the read. For CPT 95819 in 2026, the technical component is 12.74 RVUs (about $425.53) and the professional component is 1.70 RVUs (about $56.78). For 95816 the split is $357.06 technical and $56.45 professional. The read is cheap. When a self-pay quote turns out to exclude it, the surprise bill that follows is usually small, but it is a bill you did not agree to.

How long the recording runs

Price scales with recording time in discrete blocks, not smoothly. Medicare’s OPPS rates step from $220.60 for anything up to 12 hours (APC 5722), to $381.24 for each 12-to-26-hour block without video or with intermittent video (APC 5723), to $877.34 for each 12-to-26-hour block of continuously monitored video EEG (APC 5724). A three-day monitoring stay is not three times a routine EEG, it is closer to ten times.

Video and live monitoring

The jump from $381.24 to $877.34 per day is the cost of a human watching the feed in real time. That is the difference between an unattended ambulatory recording you wear at home and a staffed epilepsy monitoring unit. If a monitoring unit stay happens as a hospital admission rather than an outpatient encounter, a room charge is added: Nationwide Children’s Hospital lists a medical or surgical day at $5,800 as of January 1, 2026, on top of any testing.

Whether the setup code is billed

CPT 95700 covers the setup, patient education and takedown by an EEG technologist, and Medicare pays it $220.60 in the hospital outpatient setting. On long studies it is a real line item. Ask whether it is inside your quote.

Cash Price vs. Insurance

For a routine EEG, paying cash is often the better deal outright. A $500 posted cash rate at a neurology practice beats a $1,180 hospital charge that then gets processed against a deductible you have not met. If you have a high-deductible plan and have not hit the deductible, you are paying the negotiated rate anyway, so the only question is which negotiated rate.

Where insurance matters is the long studies. A multi-day video EEG in a monitoring unit runs into thousands of dollars, and that is the scenario where a plan’s out-of-pocket maximum does real work. Paying cash for a three-day monitoring stay to dodge a deductible is usually the wrong trade.

Two things to watch. First, a cash discount you negotiate before service is generally cleaner than a discount you argue for afterward, because hospital financial-assistance and prompt-pay policies are written for pre-service self-pay patients. Second, if you use insurance, confirm that both the facility and the reading neurologist are in network, since the reading group is frequently a separate company. Our hospital price transparency guide explains how to pull a hospital’s own posted cash price for a specific CPT code before you book.

How to Pay Less

Ask for the price by CPT code, in writing. Say the code out loud: 95816 for awake and drowsy, 95819 for awake and asleep, 95822 for sleep only. Then ask whether the quote includes the professional read (modifier 26) or only the technical component (modifier TC). A quote that does not name a code is not a quote.

Price a freestanding neurology office against the hospital. The gap between a $500 posted office cash rate and a $1,180 hospital charge for the same code is the single biggest lever available on a routine EEG. Run both through our fair price checker before you schedule.

Buy it prepaid. Marketplace listings bundle the facility and the read into one upfront price, which removes the two-bill risk entirely. The published national band for a routine EEG is $366 to $794.

Ask about the self-pay discount and charity care. Hospitals publish discounted cash prices and income-based financial assistance policies, and both apply to diagnostic testing. Start with our hospital charity care guide and the charity care checker to see whether you qualify before the bill goes out.

If a bill already arrived, get the itemized version first. Long EEG studies are billed in blocks, and block counts are a common place for errors. Request the line-by-line breakdown using our itemized hospital bill guide, check the number of 12-to-26-hour units against how long you were actually recorded, and then work the price down with our medical bill negotiation guide.

Look for sliding-scale clinics if you have no coverage at all. Federally qualified health centers and free clinics can order and sometimes host diagnostic testing on an income-based scale. Our free and sliding-scale clinic guide covers how to find them.

The Bottom Line

A routine EEG is a cheap test that gets priced expensively when a hospital is involved. Expect $366 to $794 prepaid, roughly $500 at a neurology office posting a cash rate, and up to $1,180 as a hospital list charge that still excludes the doctor’s read. Longer studies are a different category of expense: budget around $767 for 24 hours of ambulatory recording and roughly $1,089 per day for monitored video EEG at Medicare benchmark rates, before any facility markup.

If you are pricing other neurological or diagnostic testing, our guides to neuropsychological testing costs, sleep study costs and EKG costs without insurance use the same code-by-code approach. For imaging that is often ordered alongside an EEG, see MRI costs without insurance.
