My health coverage started on the first of March with Coventry Florida. Very cool I haven't had coverage for most of my adult life maybe 30yrs

Anyways Labs are covered 100% through Labcorp Test Cyp is on there covered meds list with a $15 copay to me both covered as long as they runs through my listed primary doctor which is not a problem.
The problem is HCG its not on the covered med list. My doctor has no problem prescribing it and I've been using it as part of my HRT for maybe 10yrs already. I hear its possible to request and get your the insurance company to cover none listed meds and they will if you can show them good medical reasoning for prescribing it. For instance most insurance companies won't cover ED meds for ED issues but they will if prescribed for prostate treatment.
So my question is what would be some good solid medical reasoning that can could work to get my insurance to cover HCG ???????????
