How much does a sleep apnea oral appliance cost, and what do Medicare and insurance pay?

What a custom oral appliance costs on Medicare

In 2024 Medicare allowed an average of $2,271.51 for a custom appliance for New Jersey patients and paid $1,774.95; your share after the deductible is 20 percent of the allowed amount, about $454.30.

CMS publishes what equipment suppliers bill and what Medicare allows for each code, by state. For E0486, the custom-fabricated oral appliance, the 2024 data for patients whose referring clinician practised in New Jersey cover 283 people and 284 devices. Dentists billed an average of $6,278.55, Medicare allowed $2,271.51 and paid $1,774.95. The neighbouring states were close: New York $2,263.16 allowed for 908 people, Pennsylvania $2,206.58 for 496. Nationally, 14,616 people received one, with $1,639.99 allowed on average. The gap between the billed charge and the allowed amount is why the supplier's Medicare enrollment and its acceptance of assignment matter so much to what you pay.

• Allowed amount, New Jersey average: $2,271.51. Medicare's 80 percent share is about $1,817.21; the average actually paid was $1,774.95.
• Your 20 percent with the 2026 deductible already met: about $454.30.
• If none of the $283 Part B deductible is met: $283 plus 20 percent of the remaining $1,988.51 ($397.70), about $680.70.
• A Medigap plan may pay some or all of the 20 percent; a Medicare Advantage plan sets its own cost share.

When Medicare covers an oral appliance

Only a custom-made appliance, only after a qualifying sleep test, only on your treating clinician's order, and only when a licensed dentist supplies it.

Medicare's coverage rule for oral appliances is Local Coverage Determination L33611. A custom-fabricated mandibular advancement appliance (E0486) is covered when every one of its conditions is met, and a prefabricated appliance (E0485) "will be denied as not reasonable and necessary". The order cannot come from the dentist: the LCD says the treating practitioner "does not include a dentist", and the dentist must be the one who provides and bills the device. Noridian, the Medicare equipment contractor for New Jersey, explains that a supplier can bill Medicare for equipment only after it has been enrolled and issued supplier billing privileges, so the dentist has to be enrolled as a Medicare equipment supplier.

• An in-person evaluation by your treating clinician before the sleep test.
• A Medicare-covered sleep test showing an apnea-hypopnea index (or respiratory disturbance index) of 15 or more with at least 30 events, or 5 to 14 with at least 10 events plus excessive daytime sleepiness, impaired cognition, mood disorders, insomnia, high blood pressure, ischemic heart disease or a history of stroke.
• If the index is above 30, documentation that you cannot tolerate CPAP or that your clinician considers it contraindicated.
• An order from your treating clinician written after reviewing the sleep test report.
• A custom device made, supplied and billed by a licensed dentist (DDS or DMD).

What commercial insurance pays

Most medical plans treat the appliance as equipment and set their own allowed amount; many copy Medicare's sleep-test thresholds. You owe your medical deductible and coinsurance.

Aetna's Clinical Policy Bulletin 0004 is a typical example. It considers a mandibular advancement appliance medically necessary at the same index thresholds Medicare uses, requires CPAP intolerance or a contraindication only when the index is above 30, covers a prefabricated appliance only for people who meet CPAP criteria and cannot tolerate it, and considers replacement medically necessary at the end of a 5-year reasonable useful lifetime, earlier only if your condition has changed. Dental plans rarely carry a sleep appliance benefit, so ask your medical plan first. One dental practice's published guide to these claims, a top search result for this question, gives the same order of steps: sleep test, physician order, custom device, then billing with E0486 and the sleep apnea diagnosis code G47.33.

• Is a custom oral appliance (E0486) a covered benefit under my medical plan, in network and out of network?
• Which sleep test results do you require, and must I try CPAP first?
• Is prior authorization required, and who submits it?
• What is left on my deductible, and what coinsurance applies to equipment?
• How often will the plan replace an appliance?

What you pay without insurance

Published figures for a custom appliance run from about $1,450 to $3,000 for the device and the dentist's fitting; the billed charges on Medicare claims average far more.

Prices are set by each dentist, and few publish them. A 2011 clinical report put the cost of delivering a custom appliance, which many patients pay themselves, at $2,000 to $3,000. A clinic series of 287 patients treated in 2009 and 2010 reported an average of $1,450 for custom devices against $150 for thermoplastic boil-and-bite devices. Those figures are older than this year's prices, so treat them as a range to test, not a quote. The average billed charge on Medicare claims, $6,278.55 for New Jersey patients in 2024, is the dentist's list price before Medicare's allowed amount applies; a cash price is something you agree with the practice in writing.

• Ask for one written price that names the device, the impressions or scans, the delivery visit and the number of adjustment visits included.
• Ask what a replacement or a repair costs, and how long the dentist's warranty runs.
• Ask whether the practice will give you the paperwork to submit an out-of-network claim yourself.
• A store-bought or boil-and-bite device is not covered by Medicare for sleep apnea and is not a substitute for a fitted appliance chosen with your clinician.

Costs that sit around the appliance

The diagnosis, the follow-up sleep test and the adjustment visits are billed separately from the device.

Coverage starts with the sleep test, so its cost belongs in the budget; the sleep study cost guide on this site lists 2026 New Jersey Medicare amounts for home and in-lab tests. After the appliance is adjusted, a follow-up sleep test is commonly used to check whether it is working; that is covered in the guide to the follow-up sleep test with an oral appliance. If the appliance does not control your sleep apnea, the next treatment, whether CPAP, Inspire or another option, has its own cost guide in the related reading below.
