Problems with getting Evenity insurance coverage

I was trying so hard to make sure that I didn't start Evenity until I knew that I had insurance coverage for it. Last month, I had to report that I had one less dependent (due to my son finding a job) and got kicked out of my ACA Marketplace Insurance. The UHC insurance that became available to me (after I updated my income and dependent information in ACA Marketplace) did not have Evenity in the formulary and Evenity was not eligible for pre-authorization.

Update: I talked to two UHC reps who said that my new insurance plan doesn't have Evenity in the formulary and that there is no PA for Evenity on my plan. The infusion center called up UHC and talked to a rep who said that my new insurance plan currently shows that there is a PA for Evenity. I guess that I will go for the infusion appointment and will later find out which UHC rep was correct (when my claim is processed).
