Backdoor approach hey. I can understand your situation. Don't wish to unlock the backdoor. Had the same thing for a few years but was required to go with Medicare & supplement(BCBS) prior to 65 as private insurance became to costly. Even with paying for my G4 supplies the medicare way was a great deal money wise.
BTW, obtained Dexcom G5 from Liberty on 3/27. Mailed on 3/21 via mouse delivery.
Due ambiguity by Medicare on payment, box received remains unopened as it is less money for me to continue to use G4 at present time. I use the G4 "therapeutically" to use MAC language adopted as of April 2017 and essentially would only begin to use G5 when medicare ceases the stalling on coverage.
Don't you just love Medicares evolving change in language for CGM systems. Prior to last year CGM was classified as precautionary. At this time that has changed to adjunctive & non-adjunctive with the added sub categories on therapeutic & non-therapeutic. So until medicare can resolve their own head spinning, G5 coverage is on a case-by-case basis.
