I have a Dexcom CGM and no insurance, so I must pay out of pocket. When I call Dexcom to order supplies, I tell them I pay out of pocket and they give me a 'small' break in price because I pay cash. You may want to inquire about that.I had to pay $400 for our upgrade and if you have the dexcom CGM you have the better CGM. I hate our enlite sensor and CGM. We were waked up all night long last night with false alarms. Ive ordered Gary Schiner's new book on CGM monitoring "Practical CGM"and I hope it can help us iron out our problems with it but I will scrape the money together for a Dexcom CGM if we do not have the problems Ironed out.
