- You pay 20% of the Medicare-approved amount to rent or purchase a humidifier that's used with a CPAP device or a respiratory assist device.

Your doctor may recommend services that Medicare does not cover or offers too frequently. This could end up in additional costs for you. Make sure to ask your doctor about the reasons for these recommendations and what Medicare will actually cover.
