I would not ever do business with lincare ever again. They will immediately start sending you supplies if you got a CPAP machine from them. The prices are ridiculous. I went through three masks before I got one that fit me and I was charged for all three. Good luck trying to make sense out of their bills. They will bill you for a CPAP mask and then code it as your deductible. I'm not sure why my insurance( health alliance plan )allows this .... Also the whole sleep apnea thing is quite a scam. You will never truly know if you have sleep apnea or if the doctors and the healthcare companies just want in your pockets
