Humidifiers

Humidifiers

Medicare doesn’t usually cover humidifiers or other similar items, like room heaters, dehumidifiers, or electric air cleaners.

However, Medicare covers humidifiers when there's a medical need to use them with certain covered durable medical equipment (DME), like continuous positive airway pressure (CPAP) devices, respiratory assist devices, or oxygen equipment

Your costs in Original Medicare

You pay 100% for most room humidifiers or other similar items when they're not covered for use with covered DME items. You won’t have to pay a separate amount for humidifiers used with covered oxygen equipment. The cost of a humidifier will be included in the monthly fee for your oxygen equipment.

You pay 20% of the 

Medicare-approved amount

 for the rental or purchase of a humidifier used with a CPAP device or a respiratory assist device.
