How much does a home sleep study cost, and does insurance cover it?

What you pay for a home sleep study depends on your insurance and your plan. Medicare Part B covers several types of sleep tests, including home tests that meet its rules, if you have signs and symptoms of sleep apnea. After you meet the Part B deductible, you pay 20% of the Medicare-approved amount.^{1, 2}

What affects what you pay?

Your cost depends on your insurance plan and how much of your deductible you have already paid. A deductible is the amount you pay for covered care before your plan starts to pay its share.

If you have Medicare, Part B covers sleep tests when you have clinical signs and symptoms of sleep apnea.¹ After you meet the Part B deductible, you pay 20% of the Medicare-approved amount.¹ Medicare says your exact amount can also depend on other insurance you may have and on whether your doctor accepts assignment.¹

The type of test can matter too. Medicare covers Type I tests, which are full studies in a sleep lab, only when you get them in a sleep lab facility.^{1, 2} Ask your doctor's office which test they plan to order and whether they accept assignment, so you can check your coverage before the test.

Does Medicare cover a home sleep test?

Yes, Medicare Part B covers home sleep tests that meet its rules, as long as you have clinical signs and symptoms of sleep apnea.^{1, 2} Your doctor or other health care provider must order the test.¹

Medicare's coverage rules describe four types of sleep tests. A channel is one stream of data, such as airflow or blood oxygen. Type I is an attended study in a sleep lab, where a technologist watches the recording and can step in if needed. Type II devices record at least 7 channels and can track sleep stages.²

Type III devices record at least 4 channels, including breathing movement or airflow, heart rate and oxygen level. Type IV devices may measure one or more channels but do not meet all the criteria of a higher type.²

Medicare covers Type II and Type III tests when they are done unattended, in or out of a sleep lab, which includes testing at home.² Type IV devices are covered when they measure three or more channels and one of them is airflow. They are also covered when they measure three or more channels that include actigraphy (movement), oximetry (blood oxygen) and peripheral arterial tone (a signal from the blood vessels).² For a closer look at each type, see our guide to types of sleep studies, Type 1 to Type 4.

What about private insurance?

Private insurance plans set their own coverage rules, so a good way to learn your cost is to call your plan before the test. The phone number is usually on the back of your insurance card, and these questions can help you get clear answers.

• Is a home sleep study covered under my plan?
• Do I need prior authorization before the test?
• How much of my deductible have I met this year?
• After the deductible, will I owe a copay or coinsurance?
• Do I need to use an in-network provider or testing service?
• If I need an in-lab sleep study or treatment later, how is that covered?

Write down the answers, the date of the call and the name of the person you spoke with. Your provider's office may also be able to help you check your benefits.

Why do you need a provider's order?

You need a provider's order because Medicare and the American Academy of Sleep Medicine (AASM) both call for one. Medicare says your doctor or other health care provider must order the sleep test.¹ The AASM says a home sleep apnea test is a medical assessment that must be ordered by a medical provider.³

Your provider decides whether you need the test based on your medical history and a face-to-face exam, either in person or through telemedicine.³ After the test, a physician who is board-certified in sleep medicine, or overseen by one, must review and interpret the raw data.³ Only a medical provider can diagnose sleep apnea.³

The order also matters if you need treatment later. For Medicare to cover CPAP, a machine that uses air pressure to keep your airway open while you sleep, the sleep test must have been ordered by your treating physician and done under appropriate physician supervision.⁴ If you are new to the process, our guide on how a home sleep study works walks through each step.

What if you need more testing or treatment?

If your home test is negative, unclear or did not record enough data, your doctor may recommend an in-lab sleep study.^{5, 6} A lab study is a separate test, so it is worth asking your plan how it would be covered. Our article on what happens if your home sleep test is negative explains this step in more detail.

If you are diagnosed with obstructive sleep apnea, Medicare covers an initial 12-week period of CPAP for adults who meet certain criteria.⁴ Those criteria are based on your apnea-hypopnea index (AHI) or respiratory disturbance index (RDI). AHI is the average number of times per hour that your breathing stops or becomes shallow.⁴

Under Medicare's rules, CPAP is covered if your AHI or RDI is 15 or more events per hour. It is also covered if your AHI or RDI is 5 to 14 events per hour and you have certain documented symptoms or conditions. These are excessive daytime sleepiness, impaired thinking, mood disorders or insomnia, or high blood pressure, ischemic heart disease (reduced blood flow to the heart) or a history of stroke.⁴

Your doctor can explain how your results fit these rules. Our article on common questions about CPAP therapy has more about this treatment.
