The Bottom Line
Yes, Medicare Part B covers oral appliance therapy for obstructive sleep apnea. The device is classified as durable medical equipment (DME). Your out-of-pocket responsibility depends on whether you have Original Medicare, a Medicare Advantage plan, or a Medigap supplement — each works differently. We verify your specific Medicare benefits for free and tell you exactly what you will pay before treatment begins.

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.
Medicare Requirements for Coverage
To qualify for Medicare coverage of oral appliance therapy, the following requirements must be met:
Important: Not all dental practices are enrolled as Medicare DME suppliers. Our network includes Medicare-enrolled providers who handle all billing and pre-authorization. During your free consultation, we confirm Medicare enrollment and match you with the right provider for your coverage.

Free Medicare Verification
Call us and we verify your Medicare benefits — including your plan type (Original Medicare, Medicare Advantage, or Medigap supplement), your deductible status, and your estimated out-of-pocket responsibility. We give you a clear picture before treatment begins.
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.
Pre-Authorization
We submit your sleep study results, physician prescription, and clinical documentation to Medicare. Most authorizations are processed within 5-10 business days.
Custom Fitting
Once approved, we take digital scans of your teeth and fabricate your custom oral appliance. The fitting appointment takes about 30 minutes.
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.
