Sleep apnea mouth guard cost: what you pay and what Medicare covers

What it costs and why

A custom oral appliance Some for obstructive sleep apnea isn’t a single purchase. It’s a course of care from two clinicians: a physician who diagnoses you, and a dentist who makes and adjusts the device.

We haven’t found a trustworthy national price range from a medical or government source, so we’re not quoting one. What drives the bill:

• The physician visit. AASM says a sleep doctor must diagnose sleep apnea before a dentist fits an appliance.
• The sleep test. Either a lab study or a home sleep apnea test. The cost depends on which one, and who does it.
• The dental exam. A dentist checks your teeth, gums and jaw to see if you can wear one.
• Impressions or a scan. Cleveland Clinic says the dentist takes an impression or 3D scan and a bite record. These go to a manufacturer.
• The device itself. Made by a lab to fit your teeth. Designs and materials vary.
• Fitting and adjustment visits. The dentist fits the device, then adjusts it at follow-up visits. Cleveland Clinic says it takes about two to four weeks to get used to one.
• A follow-up sleep test. AASM and Cleveland Clinic both say you may need one to check that the appliance is working.
• Replacement. Appliances wear out. Medicare treats five years as an appliance’s reasonable useful life.

An over-the-counter snoring mouthpiece costs far less, but it isn’t the same thing. No over-the-counter mouthpiece is FDA-cleared for sleep apnea.

AASM says store-bought devices aren’t recommended as a treatment for snoring or sleep apnea. Cleveland Clinic says custom-made appliances give the best results for sleep apnea.

What insurance covers, and what it doesn’t

It’s usually billed to medical coverage, not dental

Medicare treats a custom sleep apnea appliance as durable medical equipment. That means it goes through medical benefits, under HCPCS code E0486, not through a dental plan. If you have private insurance, ask whether your plan covers it under medical or dental benefits.

What Medicare requires

Medicare’s local coverage determination (LCD L33611) for oral appliances covers a custom-made appliance when all four of these are met:

1. An in-person evaluation first. A treating practitioner sees you in person, before the sleep test, to assess you for sleep apnea.
2. A Medicare-covered sleep test that shows obstructive sleep apnea. That can be a lab study or a home test. The results must show one of these:
   • An AHI or RDI (breathing events per hour) of 15 or more, with at least 30 events.
   • An AHI or RDI of 5 to 14, with at least 10 events, plus a documented related problem. The LCD lists daytime sleepiness, insomnia, a mood disorder, impaired thinking, high blood pressure, heart disease or a past stroke.
   • An AHI or RDI over 30, plus one added condition. You couldn’t tolerate a positive airway pressure (PAP) device such as CPAP, or your practitioner decides PAP is contraindicated for you.
3. A practitioner’s order after the sleep test. A physician, nurse practitioner, physician assistant or clinical nurse specialist orders the device after reviewing the test report. A dentist can’t order it.
4. A licensed dentist provides and bills for it. The dentist must be a DDS or DMD.

The companion policy article adds rules about the device itself. It must be made from a full impression or scan of your teeth, with a fixed mechanical hinge.

It must let you advance your lower jaw in steps of 1 mm or less. The device must hold its setting and stay in place during sleep.

What’s included, and what isn’t

• Follow-up for 90 days is part of the price. Medicare’s payment for the device includes fitting, adjustments and related services in the first 90 days.
• Replacement after five years. An appliance is eligible for replacement at the end of its five-year useful life. Loss, theft or irreparable damage can qualify sooner; everyday wear and tear can’t.
• Store-bought and prefabricated devices aren’t covered. Medicare denies prefabricated appliances (E0485), citing too little evidence that they treat sleep apnea.
• Snoring alone isn’t covered. An appliance for snoring without sleep apnea is billed as a non-covered item.

What you pay with Medicare

Medicare.gov says that after you meet the Part B deductible, you pay 20% of the Medicare-approved amount for durable medical equipment. Medicare only pays if the supplier is enrolled in Medicare, and for oral appliances that supplier is the dentist.

A supplier that “accepts assignment” can only charge you the deductible and coinsurance. Medicare.gov warns that a supplier who doesn’t participate, or won’t accept assignment, may charge you more.

These rules were current when we checked on September 26, 2026. Your Medicare Advantage or private plan may have different rules, prior approval steps or in-network lists.

Questions to ask

Your physician or sleep clinic:

1. Do I need a sleep test, and will it be a lab study or a home test?
2. Is my sleep apnea mild, moderate or severe, and is an oral appliance a fit for me?
3. Will you order the appliance, and will you order a follow-up sleep test to check it?

Your insurer:

1. Is a custom oral appliance for sleep apnea covered under my medical or dental benefits?
2. Do I need prior approval, and does the plan require that I try CPAP first?
3. What will I pay after my deductible, and is there an in-network dentist requirement?

The dentist:

1. Are you enrolled with Medicare, or in network with my plan, for oral appliances?
2. Do you accept assignment?
3. What’s included in the price: the exam, impressions or scan, the device, and how many adjustment visits?
4. What happens if the device breaks, or my teeth change and it stops fitting?
5. How long should this appliance last, and what does a replacement cost?

Get the answers in writing before you start. A written estimate with each item listed is easier to compare and to check against your insurer’s answer.
