Heres the Medicare skinny as I just finished the 90 days and have talked extensively with DME DOC and Medicare about the ongoing whatevers.
Doc orders test. That counts as one of your first face to face of the two visits required You get Test. Doc prescribes machine. You get the machine. Get an auto machine btw as it pays the DME the same for an auto or a straight cpap machine
You will need to take your SD card in to the DME for download in 30 60 and 90 days. Of that 90 days you need to be over 4 hrs on the machine for 70 percent of the 90 days. During the 90 days you will need to have another face to face with a doc about your apnea not before 30 days and not after 90 days. That is your 2nd and last required face to face visit
Once that period is over which I just completed, Medicare will pay 80 percent you will pay 20 percent of everything based on what medicare pays. NOT what the DME charges. In 13months you own the machine. Medicare will keep paying 80 percent of supplies. Replace your machine every 5 yrs. All that is needed for that continue is you to see a doc annually and get a letter of re certification that you benefit from the machine and its medically necessary to give to your DME so they can continue to bill for your supplies.
Thats it. The Medicare cpap shuffle LOL.
