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