I got my monthly email from Dexcom requesting my inventory of Sensors, Strips, and lancets and when I hit submit, got an alarming message which I believe said “Medicare Investigation Required” or something very similar that sent me into a mild panic. I called Dexcom customer care and after a 20 minute wait the representative read me my Medicare number and I told her that was my old Social Security number but received an updated Medicare number about 5 months ago. She took down my old number and said that it would take about 5 business days to correct and then order would be sent but if order was delayed just call back and they would send me a complimentary spare sensor. Next day received another email saying that my new number was accepted and order is on its way. All Social Security numbers on medicare cards will be changed by April 2019.
This is just a heads up in case someone gets the message because had I not called, it may have taken quite a bit longer to rectify.
