Prescribed Ozempic for .25 but my insurance says they need a PA.

I’ve had pre-diabetes for a while but was not getting treated for it (no meds). Switched doctors due to moving and in my first visit with my new doctor I was prescribed Ozempic on 12/19/2024. CVS pharmacy says they are waiting for PA from Doctor and/or Insurance. I’m not sure who is waiting for what? My doctor has already outlined that I am diabetic (A1C over 7), high blood pressure, and obese. My insurance is BCBS FEP. How long does the prior authorization take and is there anything I can do to move this along? I’ve never dealt with this stuff before so reading everything so far has me really confused. Anyone dealt with this situation? Any guidance would be greatly appreciated.
