I have been using a Dexcom G4 CGM and a Tandem t:Slim pump for 1 1/2 - 2 years. I have been waiting for two things:
Medicare coverage of CGM … which I have recently been allowed and have just received a new G5 transmitter and receiver from Dexcom. Hooray!
I then thought that I should be able to get the $399 upgrade of my t:Slim to the recently FDA-approved t;Slim X2 G5. However, Tandem told me that they will not allow me to upgrade my t:Slim (even if I pay for the upgrade myself) because Medicare does not allow a pump to be upgraded.
I have been unable to find what Medicare will/won’t allow in the way of pump upgrades on Medicare.gov … but, also can’t understand why Medicare would care/know if I paid for the upgrade, they never got a claim, and the ongoing pump supplies of cartridges and infusion sets did not change.
Does anyone have any knowledge of this issue to know whether what Tandem is telling me is right or wrong? While Medicare probably doesn’t care that I will now have to once again carry the Dexcom receiver, it shuts me out from future zero-cost software upgrades to the t:Slim system, would cost Medicare nothing extra in terms of pump supplies (if I pay for the actual upgrade), and locks me out of future safety enhancements such as the Predictive Low Glucose Suspend.
Any insights, comments, or relevant experiences would be greatly appreciated.
