The Short Answer: Yes, Medicare Covers Oral Appliances
If you have been diagnosed with obstructive sleep apnea and cannot tolerate CPAP therapy, Medicare Part B will cover a custom oral sleep appliance — also called a mandibular advancement device (MAD) — when certain conditions are met. This surprises many patients who assume CPAP is the only covered treatment.
Understanding exactly what Medicare covers, what documentation your doctor needs, and how to find a Medicare-accepted dental sleep medicine provider can save you thousands of dollars out of pocket.
What Medicare Part B Covers
Medicare classifies oral appliances as Durable Medical Equipment (DME) under Part B. Coverage applies when:
- You have a diagnosis of obstructive sleep apnea confirmed by a sleep study (polysomnography or home sleep test)
- The device is prescribed by a licensed physician
- A qualified dentist or oral sleep specialist fits and adjusts the device
- The device is FDA-cleared for the treatment of sleep apnea
Medicare typically covers 80% of the Medicare-approved amount after you meet your Part B deductible. You are responsible for the remaining 20%, though a Medicare Supplement (Medigap) plan may cover this gap.
CPAP Intolerance Requirement
Historically, Medicare required patients to demonstrate CPAP intolerance before approving an oral appliance. As of recent policy updates, this requirement has become more flexible — your physician can document that an oral appliance is the appropriate first-line treatment based on your specific clinical situation, including mild to moderate sleep apnea severity, jaw anatomy, or other medical considerations.
Talk with your sleep physician or primary care doctor about documenting your treatment preference and clinical suitability in your medical record.
What Documentation You Need
To get your oral appliance covered by Medicare, your treating physician will typically need to provide:
- A written order or prescription for the oral appliance
- Documentation of your sleep apnea diagnosis including AHI score
- Clinical notes supporting oral appliance therapy as appropriate treatment
- The specific device ordered (must be FDA-cleared for sleep apnea)
Your dental sleep medicine provider will handle the billing and prior authorization process in most cases.
Medicare Advantage Plans
If you have Medicare Advantage (Part C), coverage for oral appliances varies by plan. Most Medicare Advantage plans cover oral appliances at least as well as original Medicare, and some offer additional benefits. Contact your plan directly to confirm your specific coverage and whether pre-authorization is required.
What You Can Expect to Pay
With original Medicare, your out-of-pocket cost after the 20% coinsurance typically ranges from a few hundred dollars to over a thousand depending on the device and your deductible status. Without insurance, custom oral appliances can cost significantly more — making Medicare coverage extremely valuable for eligible patients.
How to Find a Medicare-Accepted Provider
Not all dentists bill Medicare for oral appliances — you need a dental sleep medicine specialist who is enrolled as a Medicare provider. The SkipTheCPAP directory lets you search specifically for providers who accept Medicare across all 50 states, making it easy to find a qualified specialist near you who can handle the insurance process on your behalf.
Frequently Asked Questions
Does Medicare cover the cost of adjustments and follow-up visits?
Medicare Part B generally covers follow-up visits to your physician related to your sleep apnea treatment. Adjustments to the oral appliance itself may be covered depending on how your provider bills them.
How often will Medicare cover a replacement device?
Medicare typically covers a replacement oral appliance every five years, or sooner if the device is lost, damaged beyond repair, or no longer clinically effective.
Can I get an oral appliance if I've never tried CPAP?
Yes. Recent clinical guidelines from the American Academy of Sleep Medicine recognize oral appliance therapy as a first-line treatment option, not just a CPAP alternative. Your physician can prescribe an oral appliance as your initial treatment based on your clinical profile.
