Medicare CPAP coverage may include a CPAP machine and certain replacement supplies when you meet the applicable requirements. For people with Original Medicare, Part B generally covers these items as durable medical equipment (DME). However, coverage depends on medical documentation, supplier requirements, and the rules that apply to your situation.
Understanding the process can help you know what to ask your healthcare professional and equipment supplier before they fill an order. Pro-Air Medical Supply & Equipment can answer equipment questions and help with insurance coordination. However, Medicare makes the coverage and payment decisions.
How Medicare CPAP coverage works
Original Medicare Part B may cover a CPAP machine as DME when a healthcare professional prescribes it for home use and you meet the applicable coverage requirements. Generally, Medicare requires a face-to-face evaluation and a qualifying sleep test that documents obstructive sleep apnea before it covers an initial CPAP device.
The prescribing healthcare professional must provide the required order and documentation. Medicare and its contractors review the information to determine whether it meets the applicable criteria. Therefore, a prescription alone does not guarantee coverage.
Medicare Advantage plans must cover services and items that Original Medicare covers. However, their network, prior authorization, and cost-sharing rules may differ. Check with your plan about its requirements before obtaining equipment.
Medicare CPAP coverage during the initial period
For eligible beneficiaries, Medicare generally covers an initial CPAP period of up to 12 weeks. During this time, the prescribing healthcare professional may need to document device use and follow-up care, as Medicare policy requires.
If you do not meet Medicare’s continued-coverage requirements, payment for the device may be affected. So, ask your healthcare professional and supplier what documentation you need, when to schedule follow-up, and how they handle usage information.
Do not change or stop prescribed therapy because of a coverage question. Instead, discuss treatment concerns with the prescribing healthcare professional.
What CPAP supplies may Medicare cover?
Medicare may cover eligible supplies for use with a covered CPAP machine. The specific items and quantities depend on Medicare rules, your order, medical documentation, and your circumstances.
Potentially covered supplies may include:
- A CPAP mask or mask components.
- Tubing.
- Filters.
- Headgear.
- A humidifier chamber or related accessory.
However, Medicare does not cover every item in every situation. It also sets limits on how often you may replace certain supplies. Coverage can depend on whether an item is medically necessary and compatible with your prescribed equipment.
Before ordering CPAP replacement supplies, confirm which items your plan covers, what documentation you need, and whether the supplier can bill your plan.
How often can CPAP supplies be replaced?
Medicare sets item-specific replacement limits for covered CPAP supplies. These limits do not guarantee automatic coverage at a particular time. Instead, eligibility depends on the item, the applicable coverage rules, and your circumstances.
A supplier can explain the replacement schedule for a particular item and identify any documentation you need. Meanwhile, follow the equipment manufacturer’s instructions for inspecting, cleaning, and replacing components. If a part is damaged or no longer works as intended, ask the supplier or prescribing healthcare professional what to do.
What will you pay for a CPAP machine or supplies?
With Original Medicare, you generally pay the Part B deductible and 20% of the Medicare-approved amount for covered DME after meeting the deductible. For this cost-sharing arrangement to apply as expected, the supplier must accept assignment. Otherwise, the amount you owe may differ.
A Medicare Supplement Insurance (Medigap) policy may help pay some out-of-pocket costs, depending on the policy. Similarly, Medicare Advantage plans set their own cost-sharing within Medicare rules. Check your plan’s benefits and supplier requirements.
Before receiving equipment, ask:
- Does my plan cover the CPAP machine or supply?
- Do I need prior authorization or additional documentation?
- Is this supplier enrolled in Medicare or in my plan’s network?
- How much might I owe?
- Does the estimate include the machine, setup, and supplies?
- How will the supplier order and bill for replacement supplies?
Still, do not treat a general estimate as a guarantee of payment. Your plan’s rules and the information submitted determine final coverage and costs.
Steps to take before getting a CPAP machine
To clarify the process, take these steps:
- Ask the prescribing healthcare professional about the order. Confirm that they have completed or arranged the required evaluation, sleep test, and documentation.
- Contact Medicare or your Medicare Advantage plan. Ask about coverage criteria, authorization, cost-sharing, and supplier requirements.
- Speak with the equipment supplier. Confirm that the supplier can work with your plan and ask what information they need to process the order.
- Keep records. Save the order, coverage communications, delivery documents, and details about follow-up appointments and replacement supplies.
Pro-Air works with Medicare, Medicaid, and various commercial insurance plans and can assist with insurance-related questions. However, coverage, supplier eligibility, and patient costs are not guaranteed. Confirm them for your individual plan.
Medicare CPAP coverage: common questions
Does Medicare cover a CPAP machine?
Medicare Part B may cover a CPAP machine for eligible beneficiaries who meet the evaluation, sleep-test, prescription, documentation, and supplier requirements. However, a prescription alone does not guarantee coverage.
Does Medicare cover CPAP replacement supplies?
Medicare may cover eligible replacement supplies for a covered CPAP device, subject to item-specific limits and coverage requirements. Therefore, check with your plan and supplier before ordering.
Do Medicare Advantage plans cover CPAP machines?
Medicare Advantage plans must cover items and services covered by Original Medicare. However, plan rules may include network requirements, prior authorization, or different cost-sharing. Contact your plan for details.
Can I choose any CPAP supplier?
Supplier requirements vary by plan. With Original Medicare, the supplier generally needs to meet Medicare’s DME requirements for Medicare to pay. By contrast, Medicare Advantage plans may require an in-network supplier. Confirm the rules before arranging equipment.

No. A prescription is one part of the process. Coverage may also depend on qualifying documentation, plan rules, supplier requirements, and other Medicare criteria.
