CPAP Machine Cost & Insurance Coverage Guide (2026)

1. CPAP, APAP, and BiPAP cost comparison

Sleep apnea therapy devices fall into three main categories. The right device depends on your diagnosis and your physician’s recommendation; the price difference is significant.

Note that CPAP and APAP devices share the same HCPCS code (E0601). Insurance and Medicare reimburse them at the same rate regardless of which technology the device uses. If your provider prescribes a standard CPAP but bills E0601 for an APAP at a higher price, the reimbursement rate is identical—but your coinsurance amount may be higher if the device cost is higher.

Estimate your CPAP setup cost with insurance or Medicare:

2. Annual CPAP supply costs

The machine itself is a one-time cost, but CPAP therapy requires ongoing supplies. These supplies are covered by insurance and Medicare on replacement schedules, but billing errors in supply replacement are extremely common—including billing for supplies not shipped.

At full replacement frequency, annual supply costs run $200 to $500 when paying cash. Through insurance, you pay your coinsurance percentage on each item billed. Many DME suppliers auto-ship supplies on the maximum replacement schedule whether or not you need them—a source of both waste and billing errors.

3. How insurance covers CPAP

Commercial insurance covers CPAP machines under the Durable Medical Equipment (DME) benefit, which typically has separate deductibles and coinsurance from your medical benefit. Key requirements and considerations:

• Qualifying sleep study: You must have a documented sleep study (polysomnography, CPT 95810, or home sleep test, CPT 95806) diagnosing OSA with AHI ≥5 with symptoms or AHI ≥15 without symptoms.
• Written prescription: Your physician must write a prescription specifying the type of PAP device, the prescribed pressure setting, and the diagnosis code (ICD-10 G47.33 for obstructive sleep apnea).
• DME supplier must be in-network: Using an out-of-network DME supplier can result in little to no insurance coverage. Always verify your supplier is in-network before accepting equipment.
• Prior authorization: Most plans require prior authorization for CPAP equipment. Your prescribing physician’s office typically initiates this process.
• Compliance requirements: Many insurers require documented compliance (using the CPAP at least 4 hours per night on 70% of nights over 30 consecutive days) before approving continued coverage or purchase. If you do not meet compliance, the insurer may require you to return the device.

4. Medicare coverage and rental rules

Medicare Part B covers CPAP therapy under a specific rental-to-purchase pathway. Understanding this pathway prevents unexpected charges:

1. Month 1–3 (initial rental): Medicare pays 80% of the monthly rental rate for E0601 (~$58–$70/month). You owe 20% coinsurance, approximately $12 to $14 per month.
2. Compliance verification at month 3: Your DME supplier must obtain documentation from your physician that you are using the CPAP and therapy is benefiting you. If compliance is not documented, rental stops and you may need to return the device.
3. Months 4–13 (continued rental): If compliance is verified, Medicare continues paying rental through month 13.
4. Month 13 (ownership transfer): After 13 months of covered rental, you own the CPAP outright at no additional charge. Medicare no longer pays rental after this point.
5. Ongoing supplies: After ownership transfers, Medicare continues to cover supplies on the standard replacement schedule (E0601 is no longer billed; supply codes continue).

Total Medicare rental cost over 13 months: approximately $750 to $910 billed to Medicare, of which you pay 20% coinsurance ($150 to $182) plus your Part B deductible if not already met.

5. Rental vs. purchase decision

For patients paying cash (no insurance), the rent-vs-buy decision is straightforward: buying outright is almost always cheaper if you intend to use the therapy long-term.

If you are trying therapy before committing, a 30-day cash rental at $75 to $100 is reasonable. For anyone planning to use CPAP therapy ongoing, purchasing a device directly from an online retailer (CPAP.com, CPAPsupplyusa.com, or similar) saves significantly over DME supplier pricing.

6. Buying CPAP without insurance

Buying CPAP directly without going through a DME supplier or insurance is legal and can save 30 to 50% on equipment costs. A few key points:

• You still need a prescription: CPAP devices are FDA Class II medical devices and require a physician prescription to purchase, even online.
• Online retailers are significantly cheaper: The same ResMed AirSense 11 that a hospital DME department might charge $1,400 for retails at $900 to $1,050 on direct-to-consumer sites.
• FSA and HSA funds are eligible: CPAP equipment and supplies qualify as medical expenses under IRS rules. Pay with your FSA or HSA card to use pre-tax dollars.
• ResMed and Philips recall: Philips DreamStation 1 (first-generation) devices were recalled in 2021 due to foam degradation concerns. If you are using an affected device, check the recall status at cpaprecall.philips.com. Replacement devices are available. Avoid purchasing first-generation DreamStation units on the secondary market.

7. CPAP billing codes (HCPCS) explained

DME is billed using HCPCS (Healthcare Common Procedure Coding System) Level II codes rather than CPT codes. These codes appear on your DME supplier’s itemized bill and your insurance EOB. Here are the key codes to know:

8. Common CPAP and DME billing errors

BillKarma’s data shows that 23% of sleep-related equipment claims contain billing errors. The most common errors in CPAP billing:

1. Billing for supplies not delivered: Auto-ship programs sometimes generate invoices before shipment is confirmed. Request delivery confirmation for any supply shipment billed to your insurance.
2. Exceeding replacement frequency: Billing for masks or tubing more frequently than the Medicare or insurer’s replacement schedule allows. Compare billing dates against actual shipment dates.
3. Wrong HCPCS code for device class: Billing E0470 or E0471 (BiPAP) rates when only a CPAP (E0601) was provided. BiPAP reimburses at roughly 2 to 4 times the CPAP rate.
4. Continued billing after ownership transfer: DME suppliers should stop billing E0601 rental after month 13 under Medicare. Continued rental billing after the ownership date is improper.
5. Duplicate billing for humidifier: The heated humidifier integrated into modern CPAP devices (like the ResMed AirSense 11) is included in E0601—billing separately for an integrated humidifier as an add-on accessory is a billing error.
