Understanding Sleep Apnea Coverage Under Medicare
Sleep apnea is a serious condition that affects millions of Americans over the age of 65. It causes breathing to stop and start repeatedly during sleep, leading to fatigue, heart problems, and high blood pressure. Fortunately, Medicare provides significant coverage for diagnosing and treating this condition. Knowing exactly what is covered helps you manage your health without worrying about surprise bills.
This guide breaks down the specific rules for Medicare Part B coverage. It covers sleep studies, CPAP machines, and the rental process. You will learn about the costs you might face and the equipment options available to you.
How Medicare Covers Sleep Studies
The first step in treating sleep apnea is getting a proper diagnosis. Medicare Part B covers diagnostic sleep studies when they are medically necessary. Your doctor must order the test to confirm a diagnosis of obstructive sleep apnea.
There are two main types of sleep studies covered by Medicare:
- In-Lab Polysomnography: This test is done at a sleep center. You stay overnight while technicians monitor your brain waves, oxygen levels, and heart rate. Medicare covers this if your doctor determines you need a complex evaluation.
- Home Sleep Testing: Medicare also covers home sleep tests. You take a device home to wear while you sleep. This is often used for simpler cases of suspected sleep apnea.
For these tests, you generally pay the Medicare Part B deductible. After you meet the deductible, Medicare pays 80% of the approved amount. You are responsible for the remaining 20% coinsurance. Some providers may require you to pay the full amount upfront and then bill Medicare for reimbursement.
It is important to confirm that the facility accepting your Medicare assignment before the test. This ensures they accept the Medicare-approved amount as payment in full.
CPAP Machine Coverage and the Rental Process
Once diagnosed, Medicare Part B covers the equipment needed to treat sleep apnea. This includes CPAP (Continuous Positive Airway Pressure) machines, masks, and supplies. However, Medicare does not simply sell these items. They operate under a rental model for the first 13 months.
Medicare requires you to rent the CPAP machine from a Medicare-approved DME supplier. DME stands for Durable Medical Equipment. This supplier must be enrolled in Medicare to provide the device.
The 30-Day Trial Period
After your sleep study confirms you need treatment, your supplier will provide a CPAP machine for a 30-day trial. During this time, you must use the machine for at least four hours per night on 70% of the nights you use it. This is known as compliance.
If you meet this usage requirement, Medicare continues the rental. If you do not meet the usage requirement, Medicare may stop paying for the machine. You might be asked to return the device or find a different treatment method.
The 13-Month Rental Period
After the initial 30-day trial, the rental continues for a total of 13 months. During this time, you pay a monthly rental fee. Medicare pays 80% of the rental fee, and you pay the remaining 20%. You also pay the annual Part B deductible if you have not met it yet.
At the end of the 13-month rental period, you own the CPAP machine. You do not need to pay an additional lump sum to own it. The rental payments count toward the ownership cost.
After you own the machine, Medicare continues to cover replacement parts and accessories. This includes masks, tubing, and filters. You will pay the 20% coinsurance for these supplies each time you order them.
Understanding Your Costs and Out-of-Pocket Expenses
Knowing the costs helps you budget for your treatment. Medicare Part B covers 80% of the Medicare-approved amount for both the sleep study and the CPAP rental. You are responsible for the other 20%.
Here is a breakdown of potential costs:
- Part B Deductible: In 2024, the standard Part B deductible is $240. You must pay this amount before Medicare starts covering services.
- Copays and Coinsurance: After the deductible, you pay 20% of the approved amount for the sleep study and the CPAP rental.
- Supplier Assignment: If your DME supplier accepts assignment, they agree to charge only the Medicare-approved amount. If they do not accept assignment, you might pay more.
Many beneficiaries use a Medigap plan or a Medicare Advantage plan to help cover these costs. Medigap plans often cover the 20% coinsurance. Medicare Advantage plans may have different copays or require you to use specific suppliers.
Always check with your specific plan before getting equipment. This prevents unexpected charges and ensures you use an approved provider.
Device Options: CPAP, APAP, and BiPAP
Medicare covers different types of machines depending on your specific medical needs. Your doctor will prescribe the type of device that works best for your condition.
CPAP Machines
CPAP stands for Continuous Positive Airway Pressure. This machine delivers a constant stream of air pressure. It keeps your airway open while you sleep. It is the most common treatment for obstructive sleep apnea.
APAP Machines
APAP stands for Automatic Positive Airway Pressure. This machine adjusts the pressure automatically based on your breathing. It is useful for people whose pressure needs change throughout the night. Medicare covers APAP machines if your doctor prescribes them.
BiPAP Machines
BiPAP stands for Bilevel Positive Airway Pressure. This machine provides two levels of pressure. It gives more pressure when you breathe in and less when you breathe out. Medicare covers BiPAP for patients with complex breathing issues or other lung conditions.
Your DME supplier will provide the specific device prescribed by your doctor. They will also help you choose the right mask. Masks come in different sizes and styles to fit your face comfortably.
Compliance and Documentation Requirements
Medicare requires proof that you are using the equipment to treat your condition. This is called compliance. Without proof, Medicare may stop paying for your rental.
Your CPAP machine tracks your usage. You must use the machine for at least four hours per night on 70% of the nights in a 30-day period. This usually happens during the first 90 days of treatment.
Your DME supplier will submit this data to Medicare. They use the data to determine if you qualify for the continued rental. If you do not meet the usage requirement, the supplier may ask you to return the machine.
It is important to keep your mask clean and replace it regularly. Medicare covers replacement masks every six months. You can order them through your DME supplier. Keeping the equipment clean helps prevent infections and ensures the machine works correctly.
If you move to a new state, you may need to find a new DME supplier. Medicare rules vary slightly by region. Contact your local Medicare office to find approved suppliers in your area.

Treating sleep apnea is essential for long-term health. Medicare provides robust coverage for diagnosis and treatment through Part B. Understanding the rental process and compliance rules helps you avoid financial stress.
Start by talking to your doctor about a sleep study. If diagnosed, work with a Medicare-approved DME supplier for your CPAP machine. Follow the usage guidelines to ensure continuous coverage. By staying informed, you can manage your sleep apnea effectively and protect your health.
