Does Medicare Cover CPAP Machines in 2026?

Yes — Medicare does cover CPAP machines in 2026. Medicare Part B covers Continuous Positive Airway Pressure (CPAP) therapy as durable medical equipment (DME) when it is prescribed by a doctor to treat diagnosed obstructive sleep apnea. CPAP machines are covered under Medicare’s durable medical equipment benefit because they are used at home to treat a medical condition.

Medicare CPAP coverage in 2026 is not automatic — you must meet specific diagnostic and compliance requirements before Medicare will cover your CPAP machine. The most important requirement is that you must have a formal diagnosis of obstructive sleep apnea confirmed by a sleep study — either a polysomnography (in-lab sleep study) or a home sleep apnea test — before Medicare will cover CPAP equipment.

Does Medicare cover CPAP machines for all types of sleep apnea? Medicare covers CPAP machines specifically for obstructive sleep apnea. Central sleep apnea is treated differently — typically with BiPAP or ASV machines — and Medicare has separate coverage rules for those devices which we discuss below.

Which Part of Medicare Covers CPAP Machines in 2026?

Medicare Part B — medical insurance — covers CPAP machines in 2026 as durable medical equipment (DME). DME is medical equipment that is used at home to treat a medical condition — and CPAP machines fit this definition precisely.

Medicare Part B covers CPAP machines and related supplies including:

• The CPAP machine itself
• The CPAP mask
• The CPAP tubing
• The CPAP humidifier — when part of the prescribed equipment
• Replacement supplies on a scheduled basis

Medicare Part A covers CPAP therapy provided during an inpatient hospital stay — for example if you are hospitalized and need CPAP while admitted. However home CPAP equipment is always covered under Part B as DME.

Requirements to Qualify for Medicare CPAP Coverage in 2026

To qualify for Medicare CPAP coverage in 2026 you must meet specific diagnostic and documentation requirements. Understanding these requirements before you begin the process saves significant time and prevents coverage denials.

Requirement 1 — Formal Sleep Apnea Diagnosis

You must have a formal diagnosis of obstructive sleep apnea confirmed by a sleep study. Medicare accepts two types of sleep studies for CPAP qualification:

Polysomnography (PSG) — an in-laboratory sleep study where you spend the night at a sleep center while technicians monitor your brain activity, breathing, oxygen levels, and other parameters. This is the gold standard sleep study and definitively diagnoses sleep apnea.

Home Sleep Apnea Test (HSAT) — a portable monitoring device you use at home for one or more nights. HSATs are more convenient and less expensive than in-lab studies and are acceptable for Medicare CPAP qualification for uncomplicated obstructive sleep apnea.

Your sleep study results must show that you meet Medicare’s diagnostic threshold for obstructive sleep apnea — typically an Apnea-Hypopnea Index (AHI) of 5 or more events per hour with symptoms or 15 or more events per hour regardless of symptoms.

Requirement 2 — Physician Order

Your treating physician — typically your primary care doctor, pulmonologist, or sleep medicine specialist — must write a prescription (order) for CPAP therapy documenting:

• Your diagnosis of obstructive sleep apnea
• The results of your sleep study
• The medical necessity of CPAP therapy
• The specific CPAP settings prescribed

Requirement 3 — Medicare-Enrolled DME Supplier

You must obtain your CPAP machine from a Medicare-enrolled durable medical equipment supplier. Not all CPAP suppliers accept Medicare — always verify that your supplier is enrolled in Medicare before proceeding. Your doctor or sleep center can typically recommend Medicare-enrolled CPAP suppliers in your area.

Requirement 4 — Face-to-Face Evaluation

Medicare requires that you have a face-to-face evaluation with your prescribing physician before CPAP therapy begins. This evaluation documents your sleep apnea diagnosis, symptoms, and the medical necessity of CPAP treatment.

How the Medicare CPAP Rental Process Works in 2026

One of the most important and often misunderstood aspects of Medicare CPAP coverage is the rental process. Medicare does not simply pay for you to purchase a CPAP machine outright. Instead Medicare uses a rental-to-purchase model for CPAP machines.

Months 1 to 3 — Initial Rental Period

During the first three months of CPAP therapy Medicare pays your DME supplier for the CPAP machine rental. During this initial period Medicare is evaluating whether CPAP therapy is working for you and whether you are compliant with treatment.

Your cost during months 1 to 3:

• You pay 20% of the Medicare-approved rental amount each month after your $257 annual Part B deductible
• Medicare pays 80% of the approved rental amount

The Compliance Requirement — Critical

After the first three months of rental Medicare requires documentation that you are compliant with CPAP therapy before continuing coverage. Medicare’s CPAP compliance requirement is:

• You must use your CPAP machine for at least 4 hours per night
• You must use it for at least 70% of nights over any consecutive 30-day period during the first 90 days of use

Most modern CPAP machines have built-in data recording that automatically tracks your usage. Your DME supplier and doctor can download this usage data to verify compliance. If you do not meet the compliance requirement Medicare stops paying for your CPAP machine after the initial 3-month rental period.

If you are struggling to use your CPAP machine consistently talk to your doctor before the end of the 90-day compliance period. Your doctor may be able to adjust your CPAP settings, switch your mask type, or address other issues that are preventing compliance.

Months 4 to 13 — Continued Rental

If you meet the compliance requirement Medicare continues paying the monthly rental for your CPAP machine through month 13 of therapy. Your 20% coinsurance continues to apply each month.

Month 13 — Ownership Transfer

At the end of the 13-month rental period Medicare transfers ownership of the CPAP machine to you. After 13 months of continuous rental and Medicare payment the CPAP machine becomes yours at no additional charge. This is the rental-to-purchase model Medicare uses for CPAP and other durable medical equipment.

After you own the machine Medicare continues to cover replacement supplies — masks, tubing, filters, and cushions — on a scheduled replacement basis.

What CPAP Supplies Does Medicare Cover in 2026?

Medicare covers CPAP replacement supplies on a scheduled basis in 2026. Replacement supplies are essential for effective and hygienic CPAP therapy — worn or dirty components reduce therapy effectiveness and increase infection risk.

Medicare-covered CPAP supply replacement schedule in 2026:

CPAP mask — 1 replacement per 3 months CPAP mask cushions or pillows — 2 per month CPAP full face mask cushions — 1 per month CPAP tubing — 1 replacement per 3 months CPAP filters — disposable filters 2 per month, non-disposable filters 1 per 6 months CPAP humidifier chamber — 1 per 6 months CPAP chin strap — 1 per 6 months CPAP headgear — 1 per 6 months

Medicare covers these replacement supplies at 80% after your annual Part B deductible. You pay 20% coinsurance. Your DME supplier should proactively remind you when supplies are due for replacement under the Medicare schedule.

Important note — Medicare only covers the replacement supplies listed above on the specified schedule. Replacing supplies more frequently than the Medicare schedule allows requires you to pay out of pocket even if the supplies are worn out early. Some Medicare Advantage plans have more generous replacement schedules than Original Medicare.

Does Medicare Cover BiPAP Machines in 2026?

Does Medicare cover BiPAP machines in 2026? Yes — Medicare covers BiPAP (Bilevel Positive Airway Pressure) machines in certain circumstances. BiPAP machines deliver two different air pressure levels — one for inhalation and one for exhalation — and are used for patients who cannot tolerate CPAP therapy or who have more complex respiratory conditions.

Medicare covers BiPAP machines when:

• CPAP therapy has failed — you tried CPAP and it was ineffective or intolerable
• You have a condition that specifically requires BiPAP — such as central sleep apnea, COPD, or neuromuscular disease
• Your doctor documents the medical necessity of BiPAP over CPAP

Medicare does not cover BiPAP as a first-line treatment for uncomplicated obstructive sleep apnea — you must first try CPAP and document that it was insufficient before Medicare will cover BiPAP.

The coverage process for BiPAP follows the same rental-to-purchase model as CPAP — with similar compliance requirements and a 13-month rental period leading to ownership.

• Auto-adjusting CPAP (APAP) — $600 to $1,200
• BiPAP machines — $800 to $2,000
• Travel CPAP machines — $400 to $900

CPAP Cost with Original Medicare

Medicare-approved monthly CPAP rental amount — approximately $150 to $200 per month

Your 20% coinsurance per month — approximately $30 to $40 per month

Over 13 months of rental:

• Total Medicare-approved rental — approximately $1,950 to $2,600
• Your total 20% coinsurance — approximately $390 to $520 over 13 months
• Plus $257 annual Part B deductible if not already met

After 13 months the machine is yours at no additional charge and Medicare covers replacement supplies on the scheduled basis.

CPAP Cost with Medigap Plan G

If you have Medigap Plan G your CPAP coinsurance is covered after your $257 annual Part B deductible. Your effective monthly cost for CPAP rental with Plan G after the deductible is $0 — Medicare and Plan G together cover 100% of the approved rental amount.

CPAP Cost with Medicare Advantage

Medicare Advantage plans cover CPAP machines with their own cost-sharing structure. Most Medicare Advantage plans charge a fixed copay or coinsurance for DME rental rather than the standard 20% of Original Medicare. Some Medicare Advantage plans cover CPAP at $0 after prior authorization. Always verify your specific plan’s DME coverage before obtaining CPAP equipment.

Medicare CPAP Compliance Requirements — What You Need to Know

The Medicare CPAP compliance requirement is the most common reason Medicare stops covering CPAP equipment. Understanding and meeting this requirement is essential to maintaining your Medicare CPAP coverage.

The Compliance Standard

Medicare requires you to use your CPAP machine for at least 4 hours per night for at least 70% of nights during any consecutive 30-day period within the first 90 days of therapy. In practical terms this means you must use your CPAP at least 21 out of 30 nights for a minimum of 4 hours each of those nights.

How Compliance is Documented

Most modern CPAP machines record usage data on a built-in data card or wirelessly transmit data to your DME supplier and physician through cellular or WiFi connectivity. Your supplier and doctor can review this data to verify compliance. Some machines transmit data automatically every night while others require a monthly data download.

What Happens If You Are Not Compliant

If your CPAP usage data shows you are not meeting the compliance standard after the initial 90 days Medicare will stop paying for your CPAP machine. The DME supplier will typically contact you about non-compliance before this happens. If coverage is stopped you can restart coverage if you can demonstrate adequate compliance after a break.

Tips for Achieving CPAP Compliance

If you are struggling to use your CPAP machine consistently try these strategies before your compliance period ends:

Talk to your doctor about adjusting your CPAP pressure settings — many patients do better with auto-adjusting CPAP rather than a fixed pressure setting. Try a different mask type — full face masks, nasal masks, nasal pillow masks, and hybrid masks all feel very different and comfort affects compliance significantly. Use a CPAP humidifier if you are experiencing dryness or discomfort. Use the ramp feature that starts at low pressure and gradually increases to your prescribed level. Address claustrophobia concerns with your doctor — there are techniques and mask options that can help.

Does Medicare Advantage Cover CPAP Machines?

Does Medicare Advantage cover CPAP machines in 2026? Yes — all Medicare Advantage plans must cover CPAP machines because they are a Medicare-covered service under DME. However Medicare Advantage CPAP coverage has some important differences from Original Medicare.

Prior authorization — most Medicare Advantage plans require prior authorization for CPAP machines. Your doctor and DME supplier typically handle this process but always confirm authorization is obtained before you receive equipment.

Network DME suppliers — Medicare Advantage plans require you to use in-network DME suppliers for the lowest costs. Always verify your CPAP supplier is in your plan’s network before obtaining equipment.

Cost-sharing — Medicare Advantage plans use their own cost-sharing for DME rental. Some plans cover CPAP at $0 while others charge copays or coinsurance. Check your specific plan’s DME benefits before obtaining CPAP equipment.

Compliance requirements — Medicare Advantage plans follow the same Medicare compliance requirements as Original Medicare — 4 hours per night for 70% of nights during the initial 90-day compliance period.
