Does Medicare Cover CPAP Machines? The 2026 Guide to Sleep Apnea Costs & Rules

It starts with loud snoring. Then, sudden gasping for air in the middle of the night. For millions of seniors, Obstructive Sleep Apnea (OSA) is not just a nuisance for their spouse—it is a silent killer linked to high blood pressure, heart disease, and stroke.

The gold standard treatment is a CPAP (Continuous Positive Airway Pressure) machine. But these devices are expensive. A common question echoes in doctor's offices across America: "Will Medicare pay for this?"

The answer is "Yes, BUT..." The "but" involves strict usage rules that, if ignored, could leave you with a bill for thousands of dollars. In this guide, we break down the 2026 costs, coverage rules, and the "compliance" trap you must avoid.

Guide to Sleep Apnea Costs & Rules


1. The Danger of Untreated Sleep Apnea

Before discussing costs, it is vital to understand the stakes. Sleep apnea causes breathing to stop repeatedly during sleep—sometimes hundreds of times a night.

  • Heart Health: The sudden drop in oxygen levels strains the cardiovascular system.
  • Fatigue: Chronic daytime drowsiness increases the risk of falls and car accidents for seniors.
  • Cognitive Decline: Emerging research links poor sleep oxygenation to an increased risk of dementia.

2. Medicare Coverage: The 3-Month Trial Rule

Here is where it gets tricky. Original Medicare (Part B) considers CPAP machines as Durable Medical Equipment (DME). They cover 80% of the cost, but they do NOT buy the machine for you upfront.

The "Rent-to-Own" Structure

Medicare pays for a 13-month rental period. You pay the 20% coinsurance each month. After 13 months of continuous payments and proven usage, you own the machine.

The Compliance Trap (Crucial!)

Medicare requires proof that you are actually using the device. This is known as compliance.

  • The Rule: You must use the machine for at least 4 hours per night on 70% of nights during a consecutive 30-day period within the first 3 months.
  • The Consequence: Modern CPAP machines have modems that send data to your doctor/Medicare. If you fail to meet this usage requirement, Medicare stops paying, and you must return the machine or pay the full price out-of-pocket.

3. Estimated Costs in 2026

If you have not met your Part B deductible ($240 in 2024, likely higher in 2026), you must pay that first. Afterward, here is what you can expect:

Item / Service Avg. Market Price Your Cost (With Medicare)
CPAP Machine $500 - $1,000+ 20% Coinsurance (Monthly Rental)
Mask & Tubing $150 - $250 20% Coinsurance (Replacement Schedule applies)
Sleep Study (In-Lab) $1,000 - $3,000 20% Coinsurance
CPAP Cleaners (e.g., SoClean) $200 - $350 $0 (Not Covered)

*Note: Medicare typically replaces masks every 3 months and tubing/filters regularly. Keeping up with this schedule is key to hygiene.


4. Cleaning and Maintenance: The Hidden Cost

While Medicare covers the machine and masks, they generally do not cover specialized CPAP cleaning devices (which use ozone or UV light). However, these devices are incredibly popular because hand-washing tubing daily is tedious.

Many seniors choose to invest $200-$300 out-of-pocket for a cleaner to ensure their lungs stay healthy and free from mold or bacteria buildup in the machine.


5. What If I Can't Tolerate CPAP?

Some seniors find the mask claustrophobic. If you cannot use CPAP, talk to your doctor about Oral Appliance Therapy (a custom mouthguard that holds the jaw forward). Medicare does cover these custom devices if they are custom-fitted by a dentist who participates in Medicare.


Conclusion: Don't Sleep on This

Getting a good night's sleep is the foundation of senior health. While the "compliance" rules for Medicare coverage seem strict, they are there to ensure the treatment is working. Don't let the paperwork scare you away from a device that could save your life.
