Call On Doc for Mounjaro

So I am trying to get COD to get me approved for MJ. I’ve been trying to explain to them that my insurance no longer covers Zepbound and I need a PA for Zepbound to get back on it. They said they need to send a prescription for Zepbound in to get the PA process going. Is this how it is normally done? I thought a PA had to be sent in prior to sending a prescription. I was on the phone with them explaining my case but I’m not sure if they understand what I’m meaning lol. I don’t want them to send the Zepbound to the pharmacy and then them say to pay out of pocket at the pharmacy.
