Insurance Coverage
Insurance coverage for CPAP supplies can be a bit complex, but don't worry, I've got you covered.
Medicare considers CPAP devices to be durable medical equipment and provides 80% coverage under Part B as long as you meet certain conditions. You'll need to have a sleep test, diagnosis of obstructive sleep apnea, and prescription from your doctor.

Medicaid typically follows the same guidelines as Medicare, so if you're on Medicaid, you can expect similar coverage. Your AHI must meet the same requirements as for Medicare, which includes an AHI index between 5 and 14 with a comorbidity related to obstructive sleep apnea, or an AHI of at least 15.
Most insurance plans partially cover the costs of CPAP machines and related equipment. You may be responsible for other components such as tubing, and sometimes replacement parts are covered with a limit to how many replacement parts can be purchased annually.
To determine your eligibility for CPAP therapy coverage, your insurance provider will consider your apnea-hypopnea index (AHI). Your AHI is the average number of partial or complete breathing cessation events you experience per hour.
Here's a breakdown of the AHI classification:
- Mild: AHI between 5 and 15
- Moderate: AHI between 15 and 30
- Severe: AHI greater than 30
Medicare and Medicaid partially cover CPAP machines for all three AHI indexes, provided you meet certain conditions. Other insurance providers may have different standards, so be sure to check your insurance policy to determine your specific requirements.
Supplies
Insurance coverage for CPAP supplies can be a bit confusing, but I'm here to break it down for you. The biggest upfront cost is the CPAP machine itself, but there are also supplies that need to be replaced over time.
Filters, which need to be replaced frequently, can cost between $5 and $30 each. Masks often cost $100 or more, and other equipment ranges between $20 and $100. Some rental plans may include the cost of replacement equipment, which is something to consider when comparing buying outright versus going with insurance.
Most insurance providers use the Medicare guidelines for replacing equipment, which include:
However, each provider has its own replacement guidelines, and some may allow for less frequent replacement of CPAP equipment. It's essential to check with your insurance provider to determine their specific guidelines.
Some insurance plans may cover periodic replacements when essential CPAP parts wear out, so long as you're using the CPAP as prescribed. However, additional replacements beyond what your insurance will cover will likely be paid out of pocket.
Here are some estimated costs for individual parts without insurance coverage:
Keep in mind that prices can vary based on your CPAP model and supplier.
Who's Eligible
If you're wondering who's eligible for CPAP coverage, the answer is that it depends on your insurance provider and your specific situation.
Medicare Part B covers medically necessary DME, including CPAP therapy, if your provider prescribes it for use in your home.
To be eligible for CPAP coverage, you'll typically need a prescription from your doctor, a valid sleep study, and an initial compliance period. You must also meet your insurance provider's specific requirements.
Medicare and Medicaid both require a diagnosis of obstructive sleep apnea, a prescription for a CPAP machine, and a 12-week initial period of CPAP therapy.

To qualify for Medicare coverage, your AHI (Apnea-Hypopnea Index) must be between 5 and 14 with a comorbid condition, or 15 or higher. Medicaid follows the same guidelines.
Here are the key eligibility requirements for CPAP coverage:
- Prescription from your doctor
- Valid sleep study
- Initial compliance period
- Meet your insurance provider's specific requirements
Costs and Reimbursement
You'll pay 20% of the Medicare-approved amount for CPAP machine rental and supplies after meeting your Part B deductible.
Medicare covers 80% of CPAP equipment costs under Part B, but only if your doctor and supplier are enrolled in Medicare. If they're not, you may be charged more.
If your supplier doesn't accept assignment, you could be charged the full amount upfront, and Medicare will only reimburse you for its share later.
Your doctor may recommend services that Medicare doesn't cover or offers too frequently, which could result in additional costs for you.
To avoid high costs, make sure to ask your doctor about the reasons for their recommendations and what Medicare will actually cover.

The specific amount you'll owe depends on several factors, including other insurance you may have, your doctor's charges, and the type of facility where you receive treatment.
Here are some key costs to consider:
- 20% of the Medicare-approved amount for CPAP machine rental and supplies after meeting your Part B deductible
- 80% of CPAP equipment costs covered by Medicare under Part B
- Full amount charged upfront if supplier doesn't accept assignment
- Additional costs if doctor recommends services not covered by Medicare
Obtaining and Replacing a Machine
You'll need to purchase a CPAP machine through an in-network DME supplier, which can limit your options. This doesn't mean you'll only have low-quality choices, but you might not find the best fit for you.
Most insurance policies partially cover the costs of CPAP machines and related equipment, but you may be responsible for other components like tubing. You'll typically need to meet your annual deductible before coverage kicks in.
If you need a new CPAP machine, your insurance company should replace it after five years, but the timeframe may vary depending on your healthcare provider.

Replacement Frequency of New Machines
Insurance companies generally replace CPAP machine parts every few months, but the machine itself is typically replaced once every five years.

Insurance companies use a replacement schedule for resupplying parts, so you can expect to replace tubes, masks, headgear, and filters regularly.
This can be frustrating if you need new supplies before the given timeframes, which is a big reason many people choose to buy the machine and parts themselves.
Your health insurance company should replace your CPAP machine when it's time to trade it in, typically after five years.
Keep in mind that the timeframe for when a health insurance provider will replace a piece of equipment will vary depending on who your healthcare is through.
This means you'll need to check your insurance policy to determine when your machine will be replaced.
