So sorry about your fall and I hope you are making a speedy recovery!
The last time I had an x-ray (couple of months ago) I was told it was best to remove my insulin pump and CGM although the risks of a malfunction were extremely low as the part of my body they were x-raying wasn't near where my pump/sensor were. I was told I could keep them on if I wanted to but it was my choice. Haven't heard or seen that they've changed the rules on wearing them during an x-ray though, seems a little odd to me, always stick with your gut instinct!
