Medicare may cover Continuous Positive Airway Pressure (CPAP) therapy if you’ve been diagnosed with obstructive sleep apnea. Medicare may cover a 3-month trial of CPAP therapy. Medicare may cover it longer if you meet in person with your doctor, and your doctor documents in your medical record that you meet certain conditions about the use of the device and the CPAP therapy is helping you.
If you had a CPAP machine before you got Medicare, Medicare may cover CPAP machine cost for replacement CPAP machine rental and/or CPAP accessories if you meet certain requirements.
You pay 20% of the
for rental of the machine and purchase of related supplies (like masks and tubing). The Part B
applies. Medicare pays the
to rent the machine for the 13 months if you’ve been using it without interruption. After you’ve rented the machine for 13 months, you own it.
Medicare will only cover your durable medical equipment (DME) if your doctor or supplier is enrolled in Medicare. If a DME supplier doesn't accept assignment, Medicare doesn't limit how much the supplier can charge you. You may also have to pay the entire bill (your share and Medicare's share) at the time you get the DME.
