Does Medical Insurance Cover an Oral Appliance for Sleep Apnea?

The Short Answer

In many cases, yes. Because oral appliance therapy treats obstructive sleep apnea, a medical condition, it is generally covered under your medical insurance rather than your dental plan. Coverage depends on your specific plan, your diagnosis, and your recommended treatment. To process your claim, your insurer will need a diagnosis of obstructive sleep apnea from a physician.

If you’ve been told a custom oral appliance could help you sleep better, it’s natural to wonder what it will cost and how insurance fits in. Below, we walk you through why this treatment is billed medically, what your plan will likely ask for, and how our team can help you understand your benefits before your treatment begins.

Why Medical Insurance and Not Dental?

Even though a dentist makes and fits your appliance, oral appliance therapy isn’t treating your teeth. It’s treating obstructive sleep apnea, a medical condition in which your airway becomes blocked during sleep and your breathing stops for moments at a time. Because the appliance treats a breathing disorder, it is generally covered under medical insurance as opposed to dental insurance.

Medicare draws the same line. It covers oral appliances used to treat obstructive sleep apnea under its Durable Medical Equipment benefit, not as a dental service.

This distinction affects your coverage in a few important ways:

• A diagnosis matters. Medicare does not cover an appliance used only to treat snoring without a diagnosis of obstructive sleep apnea. If snoring is your only concern, it’s worth asking your plan how it handles that.
• The type of appliance matters. A custom appliance made for sleep apnea is handled very differently from a splint made for TMJ. Medicare, for example, treats an appliance used for TMJ disorders as a dental device, not medical equipment.
• Your medical plan’s rules apply. Your medical plan’s deductible, coinsurance, and network rules will shape what you pay, not your dental plan’s.

What Documentation Your Plan Will Likely Ask For

Every plan has its own requirements, but oral appliance claims commonly rely on the same few pieces. It helps to know what they are before you start.

• A diagnosis of obstructive sleep apnea from a physician. Dentists cannot diagnose sleep apnea, so this has to come from your physician, usually after a home or in-lab sleep study.
• Your sleep study report. This shows your insurer how severe your sleep apnea is.
• A prescription for an oral appliance. When you and your doctor decide oral appliance therapy is the right treatment for you, your doctor writes a prescription and refers you to a qualified dentist.
• Notes from your physician’s evaluation. For Medicare, these notes commonly describe symptoms like snoring, daytime sleepiness, choking or gasping during sleep, pauses in breathing that someone has noticed, and morning headaches.
• CPAP history, if your sleep apnea is severe. For severe cases, Medicare requires that you were unable to tolerate CPAP or that CPAP isn’t appropriate for you. Many other plans also want CPAP tried first for severe sleep apnea.

The Role of Your Sleep Study in Coverage

Your sleep study does two jobs. It confirms your diagnosis, and it gives your insurer the information it uses to decide whether an oral appliance is medically necessary for you.

One of the key numbers on your report is your apnea-hypopnea index, or AHI. It reflects the average number of times per hour your breathing stops or becomes shallow while you sleep. Insurers often use your AHI to decide when an oral appliance can be your first treatment and when they want you to try CPAP first:

• Mild to moderate sleep apnea: Many commercial plans cover an oral appliance as a first treatment, based on your preference over CPAP. Medicare covers moderate sleep apnea, and covers mild sleep apnea when you also have symptoms or certain health conditions, such as heart disease.
• Severe sleep apnea: Plans often want to see that CPAP was tried first. Oral appliances are usually covered when you can’t tolerate CPAP.

You do not need a sleep study before your first visit with Dr. Postol. During your consultation, he will talk with you about your symptoms, review your medical history, and determine whether a sleep study is needed as part of your evaluation. If you’ve already had a sleep study, bring the results with you so we can review them together.

Your sleep study matters after treatment begins, too. Clinical guidelines recommend a follow-up sleep test to confirm your appliance is actually working, and our office communicates directly with sleep physicians as part of your care.

Questions to Ask Your Insurance Plan

A quick call to the member services number on your medical insurance card can give you a clearer picture before your treatment plan is set. Here are the questions worth asking:

1. Is a custom oral appliance for obstructive sleep apnea a covered benefit under my medical plan? (It can help to mention the billing code for a custom oral appliance, E0486.)
2. Is Gateway Center for Sleep Apnea & TMJ Therapy in network with my plan?
3. Do I need prior authorization or a referral before treatment?
4. How much of my deductible have I met this year, and when does my plan year reset?
5. What coinsurance or copay applies to durable medical equipment?
6. Does my plan require me to try CPAP first?
7. How recent does my sleep study need to be, and is a follow-up sleep test with my appliance covered?
8. How often will my plan replace an appliance, and are follow-up visits and adjustments covered?

What If You Have Medicare?

Medicare covers custom oral appliances for obstructive sleep apnea under its Durable Medical Equipment benefit when the coverage requirements are met. A few details are especially helpful to know:

• Only certain appliance designs qualify. Medicare pays for a custom oral appliance only when the specific product has been reviewed and approved for that billing code. It’s worth asking whether the appliance recommended for you qualifies.
• The appliance must come from a licensed dentist. Medicare requires that a licensed dentist (DDS or DMD) provide and bill for the appliance.
• Early adjustments are included. Fittings and adjustments during the first 90 days after you receive your appliance are included in Medicare’s payment for the device.
• Replacement follows a 5-year timeline. Medicare treats 5 years as the reasonable useful lifetime of an oral appliance. Earlier replacement may be covered for loss, theft, or irreparable damage, but not for everyday wear and tear.

If you have Medicare, let us know when you call so we can talk through your coverage with you.

What to Expect Out of Pocket

Your out-of-pocket cost depends on your insurance plan, your diagnosis, and your recommended treatment. Because the appliance runs through your medical plan, the biggest factors are usually:

• Your deductible. This is how much you pay before your plan starts sharing the cost. If you’ve already met most or all of it this year, the timing of your treatment may affect what you pay, so check before your plan year resets.
• Your coinsurance or copay. After your deductible, your plan may cover a percentage of the cost while you pay the rest.
• Network status. Seeing an in-network provider generally keeps your costs lower. Our office offers in-network coverage for sleep and participates with many insurance plans.
• Approval of your claim. If your plan’s documentation requirements aren’t met, your claim may not be paid.

If you have a flexible spending account (FSA) or health savings account (HSA), ask your account administrator whether you can use those funds toward your share of the cost.

A denied claim isn’t always the final word. Claims for oral appliance therapy are sometimes denied, and a qualified dentist who accepts your insurance can help you through the appeal process. Your state’s insurance department can also step in if a private insurer continues to deny your claim.

Frequently Asked Questions

Does dental insurance cover a sleep apnea mouthpiece?

Usually not. Oral appliance therapy for obstructive sleep apnea is generally covered under medical insurance rather than dental insurance, because it treats a medical condition.

Do I need a sleep study before my first visit?

No. You do not need a sleep study before your first appointment with Dr. Postol. Before you can get an oral appliance for sleep apnea, though, you will need a diagnosis from a physician, which usually involves a sleep study.

Will insurance cover an oral appliance if I only snore?

It depends on your plan. Medicare does not cover an appliance used only for snoring without a diagnosis of obstructive sleep apnea, so ask your plan how it handles snoring before you start.

Can I get an oral appliance covered if I can’t tolerate CPAP?

Often, yes. For severe sleep apnea, plans commonly want CPAP tried first, and oral appliances are usually covered when you can’t tolerate it. Medicare also covers an oral appliance for severe sleep apnea when CPAP isn’t tolerated or isn’t appropriate for you.

How long does an oral appliance last, and will insurance replace it?

Appliances can generally be expected to last up to 5 years, and often they last well beyond that. Medicare considers an oral appliance eligible for replacement after 5 years. Other plans set their own replacement rules, so check with yours.

What if my insurance denies my claim?

Claims for oral appliance therapy are sometimes denied, but you have options. A qualified dentist who accepts your insurance can help you appeal, and your state insurance department can help if a private insurer keeps denying the claim. If you have Medicare, you can contact Medicare directly about your concerns.
