If you have recently completed a sleep study and your doctor has confirmed obstructive sleep apnea (OSA) then the first question that will come is whether Medicare will help you pay for CPAP therapy.
The concern is not only the machine itself, but also ongoing costs for masks, tubing, filters, and replacement supplies for many patients.
Medicare does help cover CPAP therapy for patients who meet certain medical requirements. Coverage usually starts after a sleep study confirms obstructive sleep apnea and a doctor prescribes CPAP treatment.
Under Medicare Part B, approved CPAP costs are typically covered at 80% after the annual deductible is met. In 2026, the Part B deductible is $257. After that, patients are usually responsible for the remaining 20% of the approved cost unless they have supplemental insurance that helps cover those expenses.
Because sleep apnea affects many older adults, Medicare requires patients to complete a structured 90-day CPAP trial period before continuing long-term coverage. This trial helps confirm that patients are using therapy consistently and benefiting from treatment.
What Medicare Actually Covers For CPAP Therapy
Medicare Part B covers CPAP therapy under durable medical equipment (DME) benefits for patients who qualify medically. Coverage generally includes the CPAP machine itself, along with masks, mask cushions, tubing, filters, headgear, and humidifier systems when they are prescribed as part of treatment.
Rather than purchasing the machine immediately, Medicare usually begins with a rental arrangement. In most cases, the CPAP machine is rented for 13 months. If compliance requirements are met during the trial phase and therapy continues to show benefit, ownership of the machine transfers to the patient upon the end of the rental period.
Once the annual Medicare Part B deductible has been met, Medicare typically pays 80% of approved CPAP-related costs. Patients are responsible for the remaining 20% unless they have supplemental coverage such as Medigap, which may help reduce or eliminate those out-of-pocket expenses.
What You Need To Qualify For Medicare CPAP Coverage
A few medical and insurance requirements must be completed before Medicare helps you cover CPAP therapy. The process mainly helps Medicare confirm that you have sleep apnea and that you need CPAP therapy for treatment.
Sleep Apnea Diagnosis
Medicare requires a confirmed diagnosis of obstructive sleep apnea before CPAP coverage can begin. This diagnosis must be based on an approved sleep study. Both in-lab sleep studies and qualifying home sleep apnea tests are accepted when they are ordered by a physician.
The sleep study measures the apnea-hypopnea index (AHI), which shows how many times breathing slows or stops per hour during sleep.
Patients generally qualify for Medicare CPAP coverage if the sleep study shows an AHI of 15 or higher. Some patients may also qualify with an AHI of at least 5 events per hour when symptoms or related conditions such as high blood pressure, daytime fatigue, or cardiovascular disease are also present.
Home sleep testing has become increasingly common because it allows many patients to complete testing at home while still meeting Medicare requirements.
Face-to-Face Physician Evaluation
After the sleep study, Medicare also requires a physician evaluation before CPAP equipment can be approved.
During this appointment, the doctor reviews sleep apnea symptoms, sleep study results, and whether CPAP therapy is medically necessary. The physician also documents how treatment is expected to help improve breathing and sleep quality.
This step is important because Medicare uses this documentation to approve ongoing CPAP coverage.
Medicare-Approved Supplier
CPAP equipment must also come from a Medicare-approved supplier that accepts Medicare assignment.
This matters because some suppliers do not follow Medicare billing guidelines correctly. When that happens, patients may unexpectedly become responsible for much higher equipment costs.
Before accepting a CPAP machine or supplies, patients should confirm that the supplier participates properly with Medicare.
Understanding The Medicare 90-Day CPAP Trial
Many patients are surprised to learn that Medicare starts CPAP coverage with a 90-day trial period.
This trial is designed to confirm that the therapy is being used regularly and is helping improve treatment outcomes. Medicare is not questioning the diagnosis. Instead, the trial helps show that CPAP therapy is working and being used consistently at home.
During this period, patients generally need to use the CPAP machine for at least 4 hours per night on 70% of nights during a consecutive 30-day period within the first 90 days.
Most modern CPAP machines automatically record usage information, so compliance can usually be reviewed directly from the machine data.
A follow-up visit with the physician is also required during the trial period. During this appointment, the doctor reviews progress, confirms that therapy is helping, and documents whether continued treatment remains medically necessary.
What CPAP Supplies Medicare Replaces
CPAP Supply | Typical Medicare Replacement Frequency |
Mask Cushions | Every Month |
CPAP Mask | Every 3 Months |
Headgear | Every 6 Months |
Tubing | Every 3 Months |
Disposable Filters | Monthly |
Reusable Filters | Every 6 Months |
Humidifier Chamber | Every 6 Months |
Regular replacement is important because aging supplies can contribute to air leaks, skin irritation, poor mask seal, and therapy discomfort. Many common CPAP complaints are directly related to worn-out supplies rather than the machine itself.
Patients who stay on schedule with replacement supplies often experience greater comfort, fewer leaks, and improved long-term adherence to therapy.
What Medicare Usually Does NOT Cover
Although Medicare covers medically necessary CPAP equipment and replacement supplies, certain items are commonly excluded.
These often include:
- CPAP cleaning machines
- Travel accessories and carrying cases
- Non-essential comfort products
- Luxury or upgraded equipment features not considered medically necessary
- Convenience add-ons
Some patients assume all CPAP-related purchases automatically qualify under Medicare, which can lead to denied claims and unexpected expenses. Non-DME items account for a meaningful portion of CPAP-related Medicare claim denials each year.
Before purchasing optional accessories, patients should verify coverage directly with their supplier or Medicare representative.
Why CPAP Compliance Matters Beyond Medicare Rules
Medicare compliance requirements are tied directly to health outcomes.
Untreated obstructive sleep apnea is associated with increased cardiovascular strain and long-term health risks, including:
- High blood pressure
- Heart disease
- Atrial fibrillation
- Stroke
- Chronic daytime fatigue
Consistent CPAP use helps reduce repeated oxygen drops and nighttime cardiovascular stress that occur during untreated sleep apnea episodes.
Recent large-scale research involving Medicare-aged adults has shown that patients who maintain CPAP therapy consistently achieve significantly better long-term outcomes than untreated patients. Early adherence also strongly predicts long-term success, with patients who adapt successfully during the first few months far more likely to continue therapy.
For many patients, the adjustment period is temporary, but the health benefits depend on consistent nightly use.
Common Medicare CPAP Problems Patients Run Into
It is normal for you to have questions or encounter minor issues when starting CPAP therapy through Medicare. Many patients need time to get used to sleeping with the machine and wearing the mask each night.
You may feel uncomfortable with the mask at first, notice small air leaks, or find the air pressure unusual during the first few weeks. Some patients also become confused about Medicare’s usage requirements or worry about replacement supplies and extra costs.
These problems are common, especially early in therapy. In many cases, small changes to the mask fit, humidity settings, or machine setup can make CPAP much more comfortable and easier to use.
The important thing is not to stop therapy too early. Most CPAP issues can be improved when you get help early and continue working through the adjustment period.
