Does Insurance Cover a Sleep Study?

Usually, yes, when a clinician orders it because you have signs of sleep apnea. Medicare.gov says Medicare Part B covers sleep tests if you have clinical signs and symptoms of sleep apnea, and you pay 20 percent of the approved amount after your deductible. Private plans and Medicaid often cover them too, but many want approval first or want you to try a home test before a night in the lab.

At a glance.

Medicare covers home and lab sleep tests when you have signs of sleep apnea.
Medicare covers the most complete lab test only in a sleep lab facility.
Private plans often require prior approval and may ask for a home test first.
Your share depends on your deductible, coinsurance and whether the place is in network.

Why Coverage Starts With a Clinician

A sleep study is a medical test. Plans pay for it when a clinician orders it for a reason. That usually starts with a visit where you talk about snoring, breathing pauses, gasping or daytime sleepiness. If you are not sure your symptoms count, our guide to the signs you should be tested covers the ones that matter.

What Medicare Covers

Medicare.gov says Part B covers Type I, II, III and IV sleep tests and devices if you are eligible. The eligibility line is simple. You have clinical signs and symptoms of sleep apnea.

Type I is the full study in a sleep lab with a technician present. Medicare covers it only if you get it in a sleep lab facility.
Types II, III and IV include tests that can be done at home with a portable device.

Your share, per Medicare.gov, is 20 percent of the Medicare approved amount after you meet the Part B deductible. Medicare.gov also warns that a provider may recommend services Medicare does not cover or tests more often than Medicare pays for. Ask before you agree.

Home Test or Lab Night, and Why It Matters for the Bill

There are two main kinds of test. A home test uses a small device you wear for a night or more in your own bed. A lab study, called polysomnography, means sleeping at a sleep center while a technician watches. Harvard Health notes that home tests use less equipment and cost less than lab studies.

Because of that, many private plans want a home test first when it makes sense for you. A lab night is often saved for people with other health conditions, for unclear home results or for setting up treatment. Our guide on a home sleep test or a night in the lab explains when the cheaper one is the wrong one.

Private Insurance

Every private plan sets its own rules, so the only reliable answer comes from your plan. Call the member number on your card and ask these questions.

Is a sleep study covered for suspected sleep apnea?
Do you need prior authorization, and who asks for it, me or the clinic?
Do you require a home test before a lab study?
Is the sleep center I am looking at in network?
What will my deductible and coinsurance be for this test?

Write down the date, the name of the person you spoke with and any reference number. If a claim is denied later, that note helps.

Medicaid

Medicaid is run by each state, so coverage and steps differ between Ohio, Michigan, Indiana, Kentucky and everywhere else. Many states cover sleep testing when it is medically needed, often with prior approval. Ask the clinic whether they accept your state’s Medicaid plan, and call your plan to confirm what it needs before the test.

Who Gets Prior Authorization

In most cases the ordering clinician or the sleep center sends the request to your plan. You may not see it happen. That is why it is worth asking the clinic directly. Has my approval come back. If they say yes, ask for the approval number. If the test happens before approval, you may be left with the bill.

Ways to Avoid a Surprise Bill

Ask the clinic for a cost estimate before the test. Ask for the codes they plan to bill so you can check them with your plan.
Check in network status for both the sleep center and the doctor who reads the study. They can be billed separately.
Ask about follow up costs, such as the visit to go over results.
If you have no insurance, ask the clinic whether they offer a self pay price and whether a home test would work for you.

After the Test

If the study shows sleep apnea, treatment like CPAP brings its own coverage rules. If you have Medicare, read our post on the CPAP 4 hour rule before your machine arrives. Our post on what to expect at a sleep study covers the night itself.

Finding a Sleep Center

Our directory lists sleep apnea providers by state and city, and the lookup searches by name or place. Call to ask which insurance they take. A listing is not a referral, and we do not give medical advice.

Common Questions

Does Medicare cover a sleep study?

Yes, if you have clinical signs and symptoms of sleep apnea. Medicare.gov says Part B covers Type I, II, III and IV sleep tests, and you pay 20 percent of the approved amount after the Part B deductible. Type I is covered only in a sleep lab facility.

Will my insurance pay for a sleep study at home?

Often, yes. Many plans prefer a home test when it fits your case, because it costs less than a lab study. Ask your plan whether a home test is covered and whether it is required first.

Do I need prior authorization for a sleep study?

Many private plans and Medicaid plans require it. The clinic usually sends the request. Ask the clinic to confirm the approval came back before your test date.

What if I do not have insurance?

Ask the sleep center for a self pay price before you book, and ask whether a home test is an option for you. Prices vary a lot between places, so calling two or three is worth it.
