We tried to get Tricare to cover a Guardian for us last summer and were flatly turned down, even on appeal. My DH took it WAY up the Tricare chain of command, write letters, faxed documents....and we were still turned down as they deemed CGMS devices "experimental". We were able to enroll in a study and get a CGMS for free. We were assigned the Navigator and we absolutely love it, but I got the price list for it today and I'm freaking out! It's WAY more expensive than MM or Dexcom. So I'm going to ping Tricare again to cover this when our study ends in the fall. If any of you have tips on how I can get it covered, please post or PM me. Otherwise, we'll have to most likely grab an MM or a Dex on sale. It's not worth breaking the bank over!
