It's nuts how it all works. There's no consistensy between insurers. We shouldn't have to fight to get the treatment that we need, and we should all have the same options.
I had to change my insurance this year because my last insurer only covered Prolia and oral Bisphosphonates. My current policy officially covers oral Bisphosphonates, Tymlos and Teriparitide (generic only). In the 2024 formulary Evenity is "excluded". Regardless, they approved coverage for Evenity when my doctor submitted prior authorization. Someone else in the same situation with the same policy may have been denied coverage. It's a crapshoot, and it shouldn't be. And then there's the cost. OMG! The cost.
