Does Medicare cover sleep studies?

What does Medicare cover for sleep studies?

Medicare Part B covers Type I, II, III and IV sleep tests and devices. Sleep studies monitor your sleep patterns, breathing and movement to find out whether you have a sleep disorder.

Who qualifies for a Medicare-covered sleep study?

You're eligible if you have clinical signs and symptoms of sleep apnea, and your doctor or other health care provider must order the sleep test. CMS's national coverage policy for sleep testing covers these tests to help diagnose obstructive sleep apnea, and says your treating doctor can use the results to make the diagnosis.

Can I get a Medicare-covered sleep study at home?

Yes, for some types of tests. Medicare only covers Type I tests if you get them in a sleep lab facility. CMS's coverage policy for sleep testing covers these types when you have signs and symptoms of obstructive sleep apnea:

• Type I polysomnography: covered when done attended in a sleep lab facility, where a technologist supervises the recording while you sleep
• Type II or Type III devices: covered when used unattended in or out of a sleep lab facility, or attended in a sleep lab
• Type IV devices that measure three or more channels, one of which is airflow: covered when used unattended in or out of a sleep lab facility, or attended in a sleep lab
• Devices that measure three or more channels, including actigraphy, oximetry and peripheral arterial tone: covered when used unattended in or out of a sleep lab facility, or attended in a sleep lab

What do I pay for a sleep study with Medicare?

After you meet the Part B deductible ($283 in 2026), you pay 20% of the Medicare-approved amount. What you owe can also depend on other insurance you have, how much your doctor charges, whether your doctor accepts assignment, the type of facility and where you get the test, so ask your doctor or provider what the test will cost.

What happens if a sleep study shows sleep apnea?

If you're diagnosed with obstructive sleep apnea, Medicare Part B may cover a 12-week trial of CPAP therapy, including the device and accessories. CMS's CPAP coverage policy accepts a positive sleep lab study, or a positive home sleep test with a Type II, Type III or qualifying Type IV device, along with a clinical evaluation. See how Medicare covers CPAP machines.

Does Medicare Advantage or Medigap change sleep study coverage?

Medicare Advantage plans must cover all medically necessary services that Original Medicare covers, but costs vary by plan, you may need to use providers in the plan's network, and you may need the plan's approval (prior authorization) first. A Medigap (Medicare Supplement Insurance) policy helps pay your share of Original Medicare costs, like the 20% coinsurance; what it pays depends on the policy you buy.
