General Discussion

My spouse uses Libre3+ It only has two components - sensor+transmitter combined (replaced every 14 days), receiver (replaced every 5 years - but we're using the phone app).

It was a nightmare getting it set up because of the doctor's office screw up, the pharmacy screw-up, and the (almost) DME provider screw up (that one would have cost us $1800).

I hate dealing with insurance. I'm good at it, but it doesn't make it fun. I once spent 200 hours fighting them over what ultimately was a $100 bill. I won, as I have every battle I've chosen to fight. (That one was based on principle - and trying to fix the system for others who could easily be caught in the same tangled web I ended up in.)

Good Luck. Do make sure that the pharmacy is billing under DME. That was the pharmacy screw-up in our case - they always default to prescription coverage for diabetes supplies, and don't even bother to try the medical. It is usually covered under both, and nearly always cheaper (in many instances free) as DME. The Part D coverage declined the CGM - under Medicare (unlike ever other plan I've been on) it is exclusively covered under the medical portion of the plan.

How is the reliability of the Dexcom system? We've had to replace 3 sensors (out of 6) early because of sensor failure. If this keeps up, I'm going to push my spouse to consider a different system. Abbott is currently under an FDA warning letter for failure to perform quality assurance checks at the proper times to ensure quality.

ETA: My spouse was on my insurance until she hit 70 and I retired.
