I'm in a similar boat. Rexulti is the only thing that's kept me stable, yet my insurance rejected it 5 months ago and rejected it again recently. They really don't want to pay for it!

Anyway, my insurance sent me a letter in the mail telling me why they rejected it, and they listed the criteria I needed to meet in order to get it approved. The criteria was BS, but at least I know.

So imo, check your mail for a letter first. Your pdoc will have to appeal the rejection him- or herself based on the reason that was given. But knowing the reason for rejection can help you work with your pdoc to come up with a game plan.
