CPAP with Private Insurance: How DME Suppliers Work
Most private plans cover CPAP as durable medical equipment (DME) supplied by an in-network supplier, often as a rental for a set period and often with a usage check in the first months. Your costs depend on your deductible, coinsurance and whether the supplier is in network, so call your plan before the machine ships.
What a DME supplier does
A DME supplier receives the order from your clinician, verifies your insurance, gets prior authorization if needed, delivers the machine, fits your mask and teaches you how to use and clean it. They also bill your plan for resupply masks and parts.
Your plan decides which suppliers are in network. Using an out of network supplier can cost far more or not be covered at all.
Rent or buy
Many private plans pay for CPAP as a rental over several months before you own it, similar to Medicare's 13 month capped rental, while others buy it outright. During a rental, payments may stop if you do not meet the plan's usage rules.
Ask how many months, what you owe each month, and what happens if you change plans midway.
Deductibles and coinsurance
If you have not met your deductible, you may pay the full allowed amount for the early rental months or purchase. After that, coinsurance applies. Ask your supplier for a written estimate before delivery.
If your deductible resets in January, timing a new machine or a big supply order can change what you pay.
Questions to ask your plan
Is CPAP covered under my DME benefit? Which suppliers are in network near me? Is prior authorization needed? Is it rental or purchase, and for how long? Is there a usage requirement, and what is it? How often are masks and supplies covered?
Write down the date, the representative's name and a reference number for every call.
If you would rather not use the DME supplier
You can usually buy a machine or supplies out of pocket from a retailer with your prescription, but your plan may not reimburse it and it may not count toward your deductible. Some people pay cash for a travel machine or a spare mask while using insurance for the main machine.
You can also submit an out of network claim if your plan allows; ask what documents they need.

Frequently asked questions
Does private insurance cover CPAP machines?
Most US health plans cover CPAP for diagnosed obstructive sleep apnea under their DME benefit, but rules differ. Expect prior authorization, an in-network supplier and possibly a usage check.
Why does my insurance want my CPAP usage data?
Many plans, like Medicare, pay only if you use the machine regularly in the first months. Suppliers report usage from the machine's modem or SD card.
Can I choose my own DME supplier?
Within your plan's network, usually yes. Ask your clinician to send the order to the supplier you choose.
Can I switch DME suppliers?
Usually, yes, especially for resupply. Your new supplier will need your prescription and may need records from your clinician.
