Medicare Coverage for Oral Appliance Therapy

Yes, Medicare covers oral appliance therapy for obstructive sleep apnea. The device is classified as durable medical equipment (DME) under Medicare Part B. Here is everything you need to know about eligibility, costs, and the process.

The Bottom Line

Medicare Part B covers oral appliance therapy at 80% of the approved amount after your Part B deductible is met. Your typical out-of-pocket cost is the 20% coinsurance — often $200-$500. If you have a Medicare Supplement (Medigap) plan, your coinsurance may be partially or fully covered, reducing your cost to $0.

How Medicare Covers Oral Appliance Therapy

Oral appliance therapy is billed under Medicare Part B as durable medical equipment (DME). This is the same category that covers CPAP machines, wheelchairs, and other medical devices prescribed by a physician.

Coverage category:Durable Medical Equipment (DME) under Medicare Part B
HCPCS code:E0486 — Oral device/appliance used to reduce upper airway collapsibility, adjustable or non-adjustable, custom fabricated
Medicare pays:80% of the Medicare-approved amount
You pay:20% coinsurance after your Part B deductible ($240 in 2025)
Replacement:Covered every 5 years or sooner if medically necessary

Medicare Requirements for Coverage

To qualify for Medicare coverage of oral appliance therapy, the following requirements must be met:

A diagnosis of obstructive sleep apnea confirmed by a sleep study (home sleep test or in-lab polysomnography)
The sleep study must be ordered by your treating physician (primary care or sleep specialist)
A prescription for an oral appliance written by a physician (not a dentist)
The oral appliance must be custom-fabricated — over-the-counter devices are not covered
The treating dentist must be enrolled as a Medicare DME supplier
Documentation that CPAP was tried and failed, or a clinical justification for OAT as first-line therapy

Important: Not all dental practices are enrolled as Medicare DME suppliers. Our providers are Medicare-enrolled and handle all billing and pre-authorization on your behalf.

Step-by-Step: Getting OAT Through Medicare

1

Free Medicare Verification

Call us and we verify your Medicare benefits, including whether you have a Medigap supplement that covers the 20% coinsurance. We tell you exactly what you will pay before treatment begins.

2

Sleep Study & Physician Referral

If you do not already have a sleep study, we can arrange a home sleep test. Your physician writes the prescription for an oral appliance. If CPAP was tried and failed, we document this for your file.

3

Pre-Authorization

We submit your sleep study results, physician prescription, and clinical documentation to Medicare. Most authorizations are processed within 5-10 business days.

4

Custom Fitting

Once approved, we take digital scans of your teeth and fabricate your custom oral appliance. The fitting appointment takes about 30 minutes.

5

Follow-Up & Adjustment

We schedule follow-up visits to adjust the appliance for optimal comfort and effectiveness. A follow-up sleep study verifies the device is working. All follow-up visits are covered under your original authorization.

Medicare Advantage Plans

Medicare Advantage (Part C) plans — such as those offered by UnitedHealthcare, Humana, Aetna, and others — must cover everything that Original Medicare covers, including oral appliance therapy. However, the specifics of copays, coinsurance, and network requirements vary by plan.

Some Medicare Advantage plans require prior authorization, referrals from your primary care physician, or use of in-network providers. We are experienced in working with all major Medicare Advantage plans and will verify your specific plan requirements before treatment begins.

Medicare Coverage FAQs

Yes. Medicare Part B covers custom oral appliances for obstructive sleep apnea when ordered by a treating physician. The appliance is classified as durable medical equipment (DME) under HCPCS codes E0486 and E0485. You must have a qualifying sleep study confirming your diagnosis, and the appliance must be provided by a Medicare-enrolled dentist.
Medicare typically covers 80% of the approved amount after you meet your Part B deductible.

If you have a Medicare Supplement (Medigap) plan, it may cover some or all of the coinsurance.
You need a treating physician to order the oral appliance, but you do not need a formal referral in most cases. Original Medicare (Parts A and B) does not require referrals to see specialists. If you have a Medicare Advantage plan, referral requirements vary by plan. We can help coordinate with your physician to obtain the necessary order.
Yes. Medicare covers follow-up visits for oral appliance adjustment and monitoring as medically necessary evaluation and management visits.
