Medicare and Dexcom

Hello- Having problems getting my Dexcom sensor approved by Medicare.

I have issues every time I try to refill the script for my sensor for 2 years. 

It appears that the pharmacy I had been using no longer accepts the low reimbursement rate from Medicare for Dexcom products, I tried CVS but they prefer Libre so in order to get CVS to supply it, I have to go through a ton of hoops to get the sensor. They want XIFIN to review the script and said it could take up to ten days to complete that process. 

I have been without the sensor for several days now. Hoping there is no event in the middle of the night because I can’t wake up every few hours to check my sugar. 

My doctor sent over a new script to Walgreens and still waiting for prior authorization so Medicare can fill it.

Good RX says it can fil it for $ 180.00 but I shouldn’t have to since Medicare has been processing the sensor for over 2 years. 

round and round I go trying to get this refilled each month.  

Ugh…. 

any suggestions on how to speed up this process?

    ​@WilliamM791737 , I think the pharmacies give such a hard time with that is because it is considered medical equipment and they probably aren’t compensated as much as prescriptions. Since it is definitely approved by medicare, perhaps you can get the sensors reasonably fast, less fuss and inexpensive (or the same) by going through a Medicare approved Durable Medical Equipment (DME) supplier. Not sure how you find them for your area, but it might be worth the effort to search. Just a thought.
