06 Frequently Asked Questions About Medicare CPAP Coverage
What happens if I already owned a CPAP machine before enrolling in Medicare?
If you transition into Medicare with an existing machine, Medicare will not automatically cover replacement accessories or repairs. You must supply your original sleep study records proving you met Medicare diagnostic criteria when first diagnosed.
If your past test records are missing or fail to meet CMS guidelines, Medicare requires a new diagnostic sleep study. Once verified, Medicare covers replacement supplies or helps pay for a replacement machine if yours exceeds five years of age.
How do Medicare Advantage plans handle CPAP coverage compared to Original Medicare?
Medicare Advantage plans, also known as Medicare Part C, must provide at least the same baseline coverage as Original Medicare Part B. However, private Advantage plans often enforce their own network restrictions and prior authorization rules for equipment.
You must use in-network medical equipment suppliers to avoid higher out-of-pocket copayments or outright coverage denials. Review your plan’s Evidence of Coverage document annually to confirm your equipment copays and network rules.
Where can I get unbiased help if my CPAP claim is denied?
If Medicare denies your claim for a CPAP machine or sleep study, you have the legal right to file an appeal. You can seek free, confidential guidance from your State Health Insurance Assistance Program (SHIP) by visiting shiphelp.org.
SHIP counselors provide objective guidance and can walk you through the five formal levels of the Medicare appeals process. You can also call Medicare directly at 1-800-MEDICARE (1-800-633-4227) to review specific denial reasons.
Can I travel with my Medicare-covered CPAP machine?
You can travel freely throughout the United States with your Medicare-rented or owned CPAP device. Most modern CPAP devices automatically adjust to varying electrical voltages and operate smoothly during domestic travel.
If you travel, ensure your device connects to cellular networks periodically to transmit your required compliance data during your initial 90-day trial. Maintaining consistent nightly use while traveling protects your equipment coverage from sudden cancellation.
