CPAP Insurance Coverage: What Your Plan Pays in 2026

The Short Answer: Yes, CPAP Is Covered

CPAP therapy is medically recognized treatment for obstructive sleep apnea (OSA). That diagnosis makes CPAP equipment eligible under every major insurance plan type.

The coverage pathway is called Durable Medical Equipment (DME). CPAP machines, masks, tubing, filters, and humidifiers all fall under this category. Your insurer or Medicare pays a portion of each item. Your DME benefit sets the rate.

The key conditions for coverage are listed below.

• A qualifying sleep study diagnosing OSA
• A physician prescription for CPAP therapy
• An in-network DME supplier
• Meeting any compliance requirements your plan sets

Medicare Part B CPAP Coverage

Medicare covers more CPAP patients than any other single payer.

Who qualifies

Medicare Part B covers CPAP for patients who meet all three conditions.

• Enrolled in Medicare Part B
• Have a sleep apnea diagnosis from a sleep study
• Have a physician prescription for CPAP therapy

What Medicare pays

Medicare pays 80% of the approved amount. You pay the remaining 20% coinsurance after your annual Part B deductible.

The 2024 Part B deductible was $240. Check Medicare.gov for the current 2026 figure.

The 13-month rental system

Medicare does not cover CPAP as a direct purchase. Instead, Medicare rents the machine.

For the first 13 months, Medicare pays monthly rental to your supplier. Medicare pays 80%. You pay 20% each month. At month 13, ownership transfers to you. No additional cost.

After month 13, Medicare continues to cover supplies on an ongoing schedule.

The 90-day compliance requirement

This is the piece most new CPAP patients miss.

Medicare requires proof of compliance during the first 90 days of therapy. The threshold. Four hours per night on 70%+ of nights in any 30 days. Within the first 90 days.

Modern CPAP machines (AirSense 11, DreamStation 2) record usage automatically. Your DME supplier downloads this data around day 31. Then submits it to Medicare.

If compliance is met: Medicare continues covering the machine and supplies.

If compliance is not met: Medicare stops rental payments after 90 days. You may be responsible for the machine cost.

Patients struggling with compliance should call their physician before day 31. Mask fit issues, pressure settings, and humidifier settings are all adjustable. Early adjustments protect your coverage.

What Medicare covers on an ongoing schedule

After the 13-month rental period, Medicare covers replacement supplies on this schedule.

Item	Replacement Schedule
CPAP mask system	Every 3 months
Mask cushion/pillow	2 per month
Tubing	Every 3 months
Filters (disposable)	2 per month
Filters (reusable)	1 every 6 months
Humidifier chamber	Every 6 months
Headgear	Every 6 months
Chinstrap	Every 6 months

Contact your DME supplier when items are due. They verify eligibility and ship replacements directly.

Private Insurance CPAP Coverage

Most private insurance plans cover CPAP under their DME benefit. The details vary significantly by plan.

Prior authorization

Most plans require prior authorization before they cover a CPAP machine. Your physician submits prior authorization with your sleep study, diagnosis, and prescription.

Do not purchase or accept a machine before prior authorization is approved. Without it, your claim may be denied.

In-network vs out-of-network

An in-network DME supplier dramatically reduces your cost. Out-of-network suppliers may require full price and reimbursement at a lower rate.

Confirm your DME supplier is in-network before accepting a machine.

Deductibles and out-of-pocket costs

Most private plans apply CPAP costs to your annual deductible. Before the deductible is met, you pay full price. After that, you pay a copay or coinsurance of 10-30%.

Compliance requirements

Many private plans mirror Medicare’s compliance requirements. They may require 90 days of usage data before approving ongoing coverage.

Check your specific plan documents for compliance thresholds. Call your insurer’s DME benefit line if the policy language is unclear.

Supply schedules

Private plans often follow Medicare’s supply replacement schedules. Some have shorter windows. Check your plan’s DME benefit schedule for exact timelines.

Medicaid CPAP Coverage

Medicaid covers CPAP in most states. Coverage rules and qualification thresholds vary widely by state.

Most state Medicaid programs require these documents.

• Sleep study confirming OSA diagnosis
• Physician prescription
• Medicaid-enrolled DME supplier
• Periodic compliance reviews (varies by state)

Contact your state Medicaid office to confirm your state’s CPAP DME benefit. Your DME supplier’s billing team knows your state’s program.

What Insurance Covers (and What It Doesn’t)

Typically covered with DME benefit

• CPAP machine (AutoCPAP, CPAP, BiPAP)
• Standard CPAP mask system
• CPAP tubing
• Disposable and reusable filters
• Heated humidifier (attached to machine)
• Humidifier chamber/water tank
• Headgear and chinstraps

Usually covered with prior authorization

• BiPAP or ASV machines (for complex sleep apnea)
• Travel CPAP (see section below)
• Replacement machines after documented failure
• Upgraded masks for clinical necessity

Typically NOT covered

• Premium or specialty mask upgrades chosen for comfort only
• CPAP cleaning devices (SoClean, Lumin)
• CPAP travel batteries and backup power stations
• Travel bags and carrying cases
• Distilled water for humidifier

The backup power gap

Insurance does not cover backup power stations for CPAP machines. Neither Medicare nor most private plans classify portable power stations as DME.

Your cpap battery backup options are typically self-pay. HSA and FSA funds may reimburse that cost. A Letter of Medical Necessity is required. See my hsa eligible portable power station guide for the documentation process.

How to Get Your CPAP Covered: Step by Step

Step 1: Get a sleep study

Insurance requires objective evidence of OSA. A sleep study — lab-based or at-home — qualifies for most plans.

Your physician orders the study. The sleep lab bills insurance. Results typically return within 1-2 weeks.

Step 2: Get a prescription

Your physician reviews the sleep study results. An AHI (apnea-hypopnea index) of 5 or higher typically qualifies as OSA. An AHI of 15+ usually qualifies as moderate-to-severe.

The physician writes a CPAP prescription specifying pressure or authorizing auto-titrating therapy.

Step 3: Contact an in-network DME supplier

Your physician’s office often handles referrals to DME suppliers. Confirm the supplier is in-network before proceeding.

The supplier will verify your insurance coverage and prior authorization status.

Step 4: Complete prior authorization (if required)

Your physician’s office submits prior authorization with sleep study, diagnosis, and Rx. Most process in 3-10 business days.

Step 5: Receive and start therapy

The DME supplier sets up the machine with your prescription settings. They may schedule a follow-up around day 30-31 to verify compliance data.

Step 6: Confirm compliance

Use your CPAP every night. The machine records your data automatically. Meet the 4-hour / 70% threshold before the 90-day window closes.

If Insurance Denies CPAP Coverage

Denials happen. Most are reversible with the right response.

Common denial reasons

• Missing or incomplete sleep study documentation
• AHI below plan’s threshold for coverage
• Prior authorization not submitted before purchase
• Out-of-network DME supplier
• Compliance not met during the trial period

How to appeal

Every plan has a formal appeals process. Request the denial in writing. Your denial letter must state the specific reason.

Your physician can write a Letter of Medical Necessity supporting the appeal. The letter needs your diagnosis, clinical CPAP basis, and medical necessity statement.

Submit the appeal with your physician’s letter, sleep study results, and prescription. Most insurers respond to appeals within 30-60 days.

External appeals

An internal appeal denial isn’t the end. Most states allow an external appeal to an independent reviewer. Your state insurance commissioner’s office can explain the process.

For Medicare denials, the appeal process runs through the Medicare Appeals process. Your DME supplier can help navigate it.

Travel CPAP Insurance Coverage

Travel CPAP machines (like the ResMed AirMini) qualify as Durable Medical Equipment. Most plans cover them the same way they cover standard machines.

Key conditions for travel CPAP coverage.

• The machine must be clinically necessary (physician prescription required)
• Most plans treat it as a second machine and require documentation of medical necessity
• Medicare covers travel CPAPs only as a replacement for a primary machine, not as an additional unit
• Some private plans cover a travel unit separately with prior authorization

Contact your insurer before purchasing a travel CPAP. Ask if they cover a second machine or need the primary unavailable.

Using HSA and FSA for Remaining Costs

Insurance rarely covers 100% of CPAP costs. Deductibles, coinsurance, and non-covered items leave gaps.

HSA and FSA funds cover those gaps.

CPAP machines, masks, and supplies are HSA and FSA eligible. No Letter of Medical Necessity required. The FDA classifies CPAP as a Class II Medical Device. That classification makes it eligible directly under IRS Publication 502.

HSA and FSA funds cover these CPAP-related costs.

• The machine itself (coinsurance or self-pay)
• Replacement masks, tubing, and filters beyond insurance limits
• Backup power stations (with Letter of Medical Necessity)
• CPAP power cord and DC cord accessories
• Premium mask upgrades not covered by insurance

See my hsa eligible portable power station guide. For the AirSense 11 cord, see my airsense 11 power cord guide.

FAQs From CPAP Patients

Does Medicare cover CPAP automatically?

Not automatically. You need a sleep study, OSA diagnosis, prescription, and Medicare DME supplier. Medicare covers rental and supplies after that.

What AHI score qualifies for Medicare coverage?

Medicare requires an AHI of 5+ with documented symptoms (sleepiness, fatigue). Or AHI of 15+ without other symptoms.

How long does prior authorization take?

Most private insurers process CPAP prior authorization in 3-10 business days. Medicare does not require prior authorization for CPAP. The 90-day compliance review serves that function.

Can I get a better mask than what insurance covers?

Your insurer covers a standard mask system. Upgrade to a premium mask and pay the difference yourself. HSA and FSA funds cover any FDA-classified CPAP mask at full cost.

What happens if I miss the 90-day compliance window?

Contact your physician and DME supplier immediately. Document any medical reasons for low compliance (mask fit issues, illness, travel). Some plans allow exceptions with clinical documentation. An appeal may succeed.

Does insurance cover CPAP supplies indefinitely?

Yes. Keep your prescription active and keep using the machine. Most plans require annual prescription renewal to continue the supply benefit.

What if I change insurance plans?

A new plan may restart the coverage clock. Your new insurer may require a new prior authorization and compliance review. Ask your new insurer’s DME benefit line before assuming coverage continues.

Can I buy my CPAP out of pocket and get reimbursed?

Yes, but it is riskier. Buy out of pocket only after your insurer confirms reimbursement in writing. Otherwise, use an approved DME supplier to avoid claim denials.

How do I contact my insurer’s DME benefit line?

Call the member services number on the back of your insurance card. Ask specifically for the DME (durable medical equipment) benefit department. They can quote your coverage percentage, deductible status, and prior authorization requirements.

Bottom Line

CPAP insurance coverage is available through Medicare, Medicaid, and most private plans. Most patients qualify with a sleep study, prescription, and compliant DME supplier.

Three mistakes sink most claims. Prior auth skipped before purchase. Out-of-network supplier selected. The 90-day compliance window missed.

Get the sleep study. Get the prescription. Call your insurer’s DME line. Confirm prior authorization before you accept any equipment.

Your insurance likely covers more than you realize. The Ohio reader almost spent $1,200 on equipment he received for $48.

Know your coverage. Use it.
