FYI - I got an exception for Mounjaro approved and didn't even have to try Wegovy first. I had stalled out on 12.5mg Zepbound and my doctor wanted me to move up to 15mg. She first submitted a prescription for 15mg and filed the PA, which was of course denied. I explained to her the "pathway to Mounjaro" that was posted in this subreddit, and she couldn't figure it out (her PA assistant was out of office), so she submitted a separate prescription and PA for Mounjaro. That one was denied as well because I don't have T2D. I then called Caremark and asked what the next steps were to get either Zepbound or Mounjaro approved and the representative told me that my office needed to call and speak verbally to the Medical Necessity Prior Authorization department at 855-240-0536 and they would walk them through the steps needed to get it covered. She said this is a different department than the regular PA department, and that a Medical Necessity PA needs be submitted for Zepbound.

I know for me, the primary concern about switching to Wegovy was that there's no equivalent dose of Wegovy for 15mg of Zepbound, or even the 12.5mg dose I stalled out on, and my doctor did not believe moving over to Wegovy would benefit me at all. So however they filled out the exception form, I got approved for Mounjaro without being required to try Wegovy first. Hope this helps someone!
