Is medical weight loss covered by insurance or only when it´s coded as diabetes?

My formulary lists semaglutide. Underneath it says approved indication only and I've read that line enough times to be sure I don't know what it means for me tbh

What I want to avoid is one fill covered, my budget rearranged around it and then month two coming back denied

Has anyone here had it approved where obesity or metabolic risk was the documented reason? I'm wondering whether the prescriber has to word something a particular way and whether it gets re-reviewed every year
