Yes — Blue Cross Blue Shield plans generally do cover CPAP machines, treating them as durable medical equipment once you clear a few gates: a qualifying sleep study, a written prescription, prior authorization, and, in most plans, ongoing proof that you’re actually using the device. A standard CPAP retails between $700 and $1,100 without insurance, so the paperwork is worth the effort.
Who Qualifies for a Covered CPAP
BCBS requires a documented diagnosis of obstructive sleep apnea before it will pay for anything. That diagnosis comes from an overnight test at a certified sleep lab or an FDA-approved home sleep apnea test ordered by a licensed provider. Most BCBS affiliates require prior authorization for both the sleep study and the equipment that follows.
The results have to hit specific numbers on the apnea-hypopnea index (AHI), which counts how many times per hour your breathing stops or becomes dangerously shallow. Nearly all BCBS plans follow the criteria used by the Centers for Medicare and Medicaid Services: an AHI of 15 or higher qualifies you regardless of symptoms, while an AHI between 5 and 14 qualifies you only if you also have documented symptoms such as excessive daytime sleepiness, impaired cognition, mood disorders, insomnia, hypertension, ischemic heart disease, or a history of stroke.1CMS.

Prescription and Prior Authorization
Beyond the sleep study, you need a written prescription from your treating physician specifying the device type and pressure settings. Some BCBS plans also require a Certificate of Medical Necessity or a letter from your doctor explaining why CPAP is the appropriate treatment. If prior authorization is required, you’ll submit the sleep study results, prescription, and supporting medical records before the plan approves coverage. Approval timelines range from a few days to several weeks depending on how complete your paperwork is.
How You Actually Receive the Machine
BCBS rarely pays for a CPAP machine outright. Most plans structure coverage as a rental that converts to a purchase after you prove consistent use. The rental period typically runs three months as an initial trial, during which the insurer evaluates whether you’re compliant. If you meet the usage requirements, the plan continues paying rental installments until you’ve reached the purchase threshold, which varies by plan but commonly falls between 10 and 13 months total.2BCBST. Continuous Positive Airway Pressure (CPAP) Device
This structure matters. If you fail compliance during the initial trial, BCBS can discontinue coverage entirely, and you’d need to return the machine to the DME supplier or pay the remaining balance yourself. Once the rental converts to a purchase, the machine is yours.
The Compliance Rule That Keeps Your Coverage Alive
This is where most people get tripped up. The standard compliance threshold across BCBS plans is at least four hours of use per night on 70% of nights during any consecutive 30-day period within the first three months of therapy.3Blue Cross Blue Shield of Michigan. Continuing Coverage of CPAP Machines and Supplies for the Treatment of Obstructive Sleep Apnea You also need an in-person re-evaluation with your treating physician no sooner than day 31 but no later than day 91 of use.2BCBST. Continuous Positive Airway Pressure (CPAP) Device
Modern CPAP machines track usage automatically. Most current devices have built-in wireless modems that transmit nightly data using cellular or Wi-Fi connections. Older models store data on a removable memory card that your DME supplier downloads during follow-up visits. Either way, your insurer will receive the reports and use them to decide whether to continue coverage. Some plans also require annual compliance verification before authorizing replacement supplies.
Four hours is the floor. Nights when you take the mask off early cut into your 70% margin, so treating the threshold as a target rather than a minimum puts your coverage at risk.
What You’ll Pay Out of Pocket
Even with coverage, you won’t escape costs entirely. CPAP falls under your plan’s DME benefit, so your annual deductible applies first. Deductibles vary widely, from a few hundred dollars to several thousand. Once you’ve met it, coinsurance kicks in. A typical BCBS plan covers 70% to 80% of the remaining cost, leaving you responsible for 20% to 30%, though some plans split costs 50/50.
During the rental period, you pay your coinsurance share of each monthly rental payment rather than one lump sum. If the rental converts to a purchase after the required months, your total coinsurance payments effectively become your purchase price.
After the machine is yours, repairs and replacement parts for worn-out components remain eligible for DME coverage as long as the equipment still meets the plan’s general coverage criteria and the repair is necessary to keep it functional.4BCBSTX Medical Policy. DME Introduction
Paying With an HSA or FSA
CPAP machines and supplies qualify as eligible medical expenses under both Health Savings Accounts and Flexible Spending Arrangements.5FSAFEDS. Eligible Health Care FSA (HC FSA) Expenses You can use these accounts to cover your deductible, coinsurance, and any replacement supplies your plan doesn’t fully reimburse. Keep itemized receipts showing the specific equipment purchased.
Where You Buy the Equipment Changes the Price
In-network DME suppliers have pre-negotiated rates with BCBS, which means lower out-of-pocket costs. These suppliers also handle prior authorization paperwork and bill BCBS directly, so you’re not chasing reimbursements.
Out-of-network suppliers charge whatever they want, and BCBS will reimburse only its allowed amount. Some plans reimburse a smaller percentage for out-of-network DME, and a few won’t cover it at all. Even when partial reimbursement is available, you’ll typically pay the full price upfront and submit a claim yourself. Before ordering from any supplier, call the number on your insurance card and confirm the supplier is in-network and that your equipment has been pre-authorized.
Replacement Supplies and Schedules
CPAP masks, cushions, tubing, and filters wear out, and BCBS covers replacements on a set schedule. Exceeding the allowed frequency means paying out of pocket. Typical maximum replacement intervals under BCBS plans:3Blue Cross Blue Shield of Michigan. Continuing Coverage of CPAP Machines and Supplies for the Treatment of Obstructive Sleep Apnea
- Mask cushions and nasal pillows: up to 2 per month
- Complete mask system (full face, nasal, or oral): 1 every 3 months
- Tubing: 1 every 3 months
- Disposable filters: up to 2 per month
- Non-disposable filters: 1 every 6 months
- Headgear and chinstraps: 1 every 6 months
Suppliers cannot ship more than a three-month supply at a time regardless of your schedule. And just because a replacement is available doesn’t mean you need it yet. Order when you notice wear, and your supplies will stretch further.
BiPAP and Oral Appliances
CPAP isn’t the only sleep apnea treatment BCBS covers, though the alternatives come with stricter requirements. A BiPAP (bilevel positive airway pressure) device delivers different pressure levels for inhaling and exhaling, and BCBS generally covers one only after documented evidence that CPAP alone was insufficient. CMS criteria for upgrading require measurable clinical indicators such as worsening blood gas levels or continued oxygen desaturation despite CPAP use, along with a follow-up sleep study.6CMS. Respiratory Assist Devices The same compliance monitoring and rental-to-purchase structure applies.
For patients who cannot use any positive airway pressure device, BCBS may cover a custom-fitted oral appliance that repositions the jaw or tongue. Coverage typically requires documented evidence that CPAP, APAP, or BiPAP therapy has failed or that the patient has a medical reason making those devices inappropriate. The appliance must be custom-fabricated and fitted by qualified dental personnel. Prefabricated, over-the-counter oral appliances are not covered.7Blue Cross and Blue Shield of Vermont.

What BCBS Typically Won’t Cover
A few CPAP-related purchases consistently fall outside coverage:
- A second, portable travel CPAP. BCBS covers one machine per patient, and a smaller unit for travel is considered a convenience item.8Blue Cross Blue Shield of Florida. Positive Airway Pressure Devices – Medical Coverage Guideline
- CPAP cleaning machines. Ozone generators and UV light sanitizers sold under brand names such as SoClean are treated as convenience items, and the FDA has not cleared any device for cleaning CPAP equipment.9FDA. Do You Need a Device That Claims to Clean a CPAP Machine?
- Batteries and backup power supplies, which are excluded as non-medically-necessary accessories under most BCBS plans.
Regular cleaning with warm soapy water and air drying remains the manufacturer-recommended approach.
If Your Claim Is Denied
Denials for CPAP equipment usually land in one of three buckets: insufficient documentation of medical necessity, missing prior authorization, or failure to meet compliance requirements. The denial letter specifies the reason and includes appeal instructions.
Start by reviewing the explanation of benefits and comparing the denial reason against your plan’s actual coverage guidelines. A surprising number of denials stem from paperwork problems rather than genuine coverage disputes. If your sleep study results or prescription weren’t attached, resubmitting the complete package often resolves the issue without a formal appeal.
If the denial holds, BCBS offers a multi-level internal appeal. The first level is a reconsideration request where you can submit additional medical evidence, updated physician letters, or corrected documentation. A second-level appeal may involve review by an independent medical professional within the insurer’s network. Standard appeal decisions typically come within 30 calendar days, and expedited reviews for urgent situations are decided within 72 hours.10Blue Cross and Blue Shield of Minnesota. Appeals and Grievances – Care Coordination
If internal appeals fail, federal law requires every health insurer to offer an external review. An independent review organization with no ties to BCBS examines your case from scratch. Your state may run its own external review program, or the federal Department of Health and Human Services oversees the process if your state doesn’t meet the minimum standards.11HealthCare.gov. External Review Your denial letter and explanation of benefits should include contact information for the review process that applies to your plan. A supporting letter from your sleep specialist, along with documented compliance data if available, strengthens your case at every level.
