I think no matter what the system, there are people who abuse and people who don’t. Unfortunately, do to their own bragging or via spotlight from others, we more often hear about those that abuse.
I think there are a significant number of people out there who do restarts for the same reason some people ration insulin - they can’t afford it.
It seems with any system, the difficulty is always finding a balance where the majority of people using the system get what they need. Unfortunately, the middle ground always allows for some to abuse it, and others to get less than they really need.
On terms of cost, I can say that I restart sensors. However, I don’t have a stockpile. I have the philosophy that if “it isn’t broke, don’t fix it.” Restarting a sensor saves me money and the insurance company money. As a matter of fact, when I switched from the guardian to the dexcom, even after the dexcom stuff arrived, I finished out my medtronic supplies.
I think it’s important to add that logic is almost never a part of the insurance claims process. It is a tough fight to get insurance to comprehend why I used 3 sensors one month and only 2 the next. It was a fight I made time for, but I also understand a fight not everyone is willing or able to make. I can see why some folks, therefore, choose to get 3 sensors per month, even if they have sensors left.
