How CPAP coverage works
- Get diagnosed. Your doctor evaluates you and orders a sleep test. Medicare covers CPAP for obstructive sleep apnea.
- Start a 12-week trial. Medicare covers the CPAP device, accessories and therapy for 12 weeks.
- See your doctor in person. To keep coverage after the trial, your doctor documents in your record that you meet Medicare's conditions and that CPAP is helping you.
- Keep using it. Medicare pays the supplier to rent the machine for 13 months of continuous use. After 13 months, you own it.
Masks, tubing and other supplies
Medicare covers CPAP accessories, such as masks, cushions, tubing, headgear and filters, on a replacement schedule when they're needed. Your supplier tracks when you're due. Buying extras early or from a supplier not enrolled in Medicare can leave you paying the full price.
What you pay
After the Part B deductible ($283 in 2026), you pay 20% of the Medicare-approved amount for the machine rental and for supplies. Medicare pays only suppliers enrolled in Medicare. Choose one that accepts assignment: for a rental, the supplier must accept assignment for every rental month, or you could pay the full cost up front and wait for Medicare's share. A Medigap policy pays part or all of the coinsurance.
If you live in Oregon
- Rural areas: in much of eastern and southern Oregon, CPAP supplies often come by mail. Confirm the supplier is enrolled in Medicare and accepts assignment before you order.
- Medicare and OHP: OHA lists CPAP devices among covered OHP medical equipment. If you have both, Medicare pays first and OHP can help with Medicare costs. See OHP and Medicare.
- Medicare Advantage: plans must cover CPAP but may require a network supplier and prior authorization. Medicare Advantage plans may offer extra benefits such as dental, vision, hearing or fitness. Extra benefits vary by plan and county, may have limits and costs, and not every plan offers them. Check a plan's Summary of Benefits or Evidence of Coverage.
You can request a call from a licensed insurance agent to compare plans from the companies they work with.

Frequently asked questions
Does Medicare cover the sleep study?
Yes. Part B covers sleep tests your doctor orders to diagnose sleep apnea, including some home sleep tests, with the usual Part B deductible and coinsurance.
I had a CPAP before Medicare. Will Medicare replace it?
Medicare may cover a rental or replacement machine and supplies if you had a CPAP before you got Medicare and you meet certain requirements, such as a new evaluation by your doctor.
What happens if I stop using my CPAP during the trial?
Medicare continues coverage after the trial only if your doctor sees you in person and documents that you're using the machine and it's helping. CPAP machines record use, so low use can end coverage.
Does OHP cover CPAP for people with Medicare?
OHA lists CPAP devices among the medical equipment OHP covers. If you have both, Medicare pays first, and OHP can help with Medicare cost sharing.
