Thanks @jbowler! I actually think I may have the CMS site bookmarked, but will check. If not, I appreciate the reference! I’ll try to remember to check there first on other questions! ---

> [@TomH](#): > > I actually think I may have the CMS site bookmarked That web site is a nightmare on acid. It’s something that requires special qualifications, like the one your endo’s “medical billing specialist” has, to know where to look; I just use Goggle and a knowledge of a few keywords; “billing code” is a good one. ---

Looking at the graph, I can see why you questioned it. It does look a bit jumpy compared to a smoother trend. Good that things settled later though. I think a lot of people debate whether to replace it or wait it out. [Previous page](https://forum.fudiabetes.org/t/how-reliable-are-cgms-and-who-cares/15975.md?page=3)
