This is the second system my daughter has had. Coincidentally (or is it?) her 1st one died with an "internal hardware issue" I would say within a week after warranty was up. I had a different insurance company then. So then our insurance changed to UMR (united) so we purchased the new system through them, which was covered at 90%. Now this one died with another internal hardware issue, once again, within weeks (if that) after warranty was up. Now, insurance coverage states she's only eligable for 1 in a lifetime!! Same goes for the pump. How ridiculous is that?? I wrote up a letter to send along with her letter of medical necessity from 2 years ago to fight them on this. Has anyone had this happen and what did you have to do?? Also, it seems so strange to me that this dexcom system only works for such a short period of time!!! Is this their way to make money. I told them that they probably program them to die after a certain time period, lol!! Ashlee's nurse said I should check into it on the better business bureau to see if this happens frequently. Thanks for any advise!
