Your Guide to Medicare Sleep Apnea Coverage in 2026
For anyone navigating a sleep apnea diagnosis or simply wondering whether they might be affected, knowing how to make the most of Medicare benefits can be a game changer. Getting the right diagnosis and treatment shouldn't have to come with financial uncertainty, and that's exactly where understanding your coverage becomes so important. This guide takes a closer look at how Medicare currently supports the costs associated with diagnosing and treating sleep apnea, along with what beneficiaries can reasonably expect when it comes to coverage going into 2026.
Navigating Medicare for a long term condition such as sleep apnea involves understanding both medical requirements and insurance rules. While the core structure of Medicare coverage is relatively stable, details can change from year to year, so it is helpful to know how coverage generally works now and what to monitor as 2026 approaches.

Understanding sleep apnea and why treatment matters
Sleep apnea is a sleep related breathing disorder in which a person stops or reduces breathing repeatedly during the night. Obstructive sleep apnea happens when throat tissues collapse and block the airway. Common signs include loud snoring, gasping during sleep, waking unrefreshed, morning headaches, and daytime fatigue.
Untreated sleep apnea is linked to high blood pressure, heart disease, stroke, type 2 diabetes, and increased risk of motor vehicle and work related accidents. Effective treatment can improve daytime alertness, mood, and quality of life, and may reduce long term risks. Because of these health impacts, Medicare generally treats properly diagnosed sleep apnea as a medically necessary condition, which is central to coverage decisions for tests and equipment.
How CPAP coverage works
For many people with obstructive sleep apnea, continuous positive airway pressure therapy, often called CPAP, is the first line treatment. Under traditional Medicare, CPAP machines are usually covered under Part B as durable medical equipment when specific criteria are met.
Typically, a Medicare enrolled clinician must evaluate you for symptoms of sleep apnea and order an approved sleep study. The study may be done in a sleep lab or, in some cases, using certain types of home sleep apnea tests. If the study confirms a qualifying level of sleep apnea, your clinician can prescribe CPAP.
Medicare coverage often starts with a trial period, commonly around 12 weeks, to see if CPAP helps and if you are able to use it regularly. Continued coverage can depend on both clinical improvement and documented use of the machine for a minimum number of hours on most nights. The machine is usually provided on a rental basis through a Medicare enrolled durable medical equipment supplier, with monthly payments up to a capped period, after which you typically own the device.
What specific equipment is covered
When Medicare covers sleep apnea treatment, it generally does not only cover the CPAP machine itself. Related items considered medically necessary can also fall under Part B coverage, again when ordered and supplied according to Medicare rules.
Commonly covered items may include the CPAP or bilevel device, certain masks and headgear, tubing, filters, and water chambers for heated humidifiers. There are usually limits on how often each item can be replaced within a given time frame, such as masks or cushions every few months and filters more often. These replacement schedules are designed to reflect normal wear and hygiene needs.
In addition, Medicare may cover diagnostic sleep studies that lead to your diagnosis, as well as some follow up visits with your clinician to evaluate how treatment is working. Specialized options, such as bilevel devices or certain oral appliances, are often subject to additional medical necessity rules and documentation.
Looking ahead to sleep apnea coverage in 2026
Medicare coverage for sleep apnea in 2026 will continue to be shaped by federal regulations, annual Medicare payment rules, and decisions made by regional Medicare contractors. While the broad framework of coverage for sleep studies and positive airway pressure therapy has been in place for years, details can shift over time.
Areas that may be especially important to watch include how Medicare handles home sleep apnea testing, requirements for documenting CPAP use, replacement intervals for supplies, and rules affecting durable medical equipment suppliers. Telehealth policies and remote monitoring rules have also been evolving and could influence how follow up care is delivered.
Because these details are updated through official Centers for Medicare and Medicaid Services communications, beneficiaries and caregivers should review the Medicare and You handbook for the relevant year, check the official Medicare website, and confirm specifics with plan representatives as 2026 approaches.
Medicare costs for sleep apnea care
Even when Medicare covers sleep apnea treatment, beneficiaries usually share in the costs. Under Part B, you are typically responsible for the annual Part B deductible and then about 20 percent of the Medicare approved amount for covered services and equipment, with Medicare paying the remaining 80 percent. The exact deductible and approved amounts can change each year.
If you have a Medigap policy, some or all of that 20 percent coinsurance may be covered according to the plan. If you are in a Medicare Advantage plan, your costs will follow that plan’s copay and coinsurance rules, though the basic coverage framework must be at least as comprehensive as traditional Medicare.
Below is an example of how costs may look in practice. These figures are general estimates based on typical ranges and can vary by location, supplier contracts, and year.
| Product or Service | Provider | Cost Estimation |
|---|---|---|
| CPAP machine rental under Part B | Apria Healthcare durable medical equipment supplier | Medicare approved amounts for the device over the rental period often total around 500 to 1,000 dollars; beneficiary usually pays about 20 percent coinsurance after the Part B deductible. |
| Bilevel positive airway pressure machine when medically necessary | Lincare durable medical equipment supplier | Medicare approved totals can range from roughly 1,200 to 1,600 dollars or more; typical beneficiary share is about 20 percent coinsurance after the deductible. |
| In lab overnight sleep study polysomnography billed to Part B | Hospital based sleep lab accredited by the American Academy of Sleep Medicine | Medicare approved charges are often in the 600 to 1,000 dollar range; the beneficiary portion is generally about 20 percent coinsurance after the deductible. |

Frequently asked questions
Beneficiaries and families often have similar questions about Medicare sleep apnea coverage in 2026 and beyond. A common concern is whether Medicare Advantage plans cover CPAP the same way as traditional Medicare. In general, Medicare Advantage plans must cover medically necessary services at least as fully as traditional Medicare, but they may use different supplier networks, prior authorization processes, and cost sharing structures, so it is important to review each plan’s documents.
Another frequent question is how often Medicare will help pay for a new CPAP machine. Under current rules, Medicare typically treats the machine as a rental for a fixed number of months, after which you own it. Replacement machines may be considered after a certain period when the original device is no longer working properly, but this depends on documentation and prevailing coverage policies at the time.
People also ask whether oral appliances for sleep apnea are covered. Medicare coverage for certain custom oral appliances used to treat obstructive sleep apnea can be available in some situations, usually when specific medical necessity criteria are met and when the device is provided by a qualified clinician enrolled with Medicare as a supplier. Coverage in this area tends to be more narrowly defined than CPAP coverage and may evolve as policies are updated.
Questions about travel machines, cleaning devices, and accessories are also common. Medicare generally focuses on items considered medically necessary for treatment, so not all travel specific devices or convenience accessories are covered. Before purchasing additional equipment, it is wise to confirm whether the item is eligible for Medicare payment and what your potential out of pocket costs may be.
In summary, Medicare coverage for sleep apnea care combines clinical rules about diagnosis and treatment with insurance rules about equipment, suppliers, and cost sharing. By understanding the basic structure of coverage today and paying attention to official updates, beneficiaries in the United States can better prepare for how their sleep apnea care may be handled in 2026 and beyond.
