@### My insurance also doesn't consider CGM to be a necessity, so won't cover it. But I bio-hacked a bit:
- I use G5 system, but change the transmitter batteries myself, so costs ~$10 per year for that, but there may be a $100 initial cost for the first used transmitter if you don't have one.
- I use XDrip+ on my Android phone to monitor, so $0 there. And it is MUCH more functional than any other app I've used.
- XDrip+ does not force me to change sensors after 7 days, so i keep using one until the readings get noisy or don't follow my typical patterns, usually 15 to 30 days. So I need maybe 18 sensors per year.
- I purchase private party sensors for about $35 to $45 each, sometimes Ebay, sometimes individuals on places like HelpAround. So about $700 per year there.
So, there is still a cost, but with some DIY effort, way less than the official Dexcom regimen totaling ~$7k.
Just sharing how I've helped my costs for a CGM.
