Hi Tommygun,
I can't speak for BCBS of Alabama, but I have FloridaBlue, and GCS and hormone therapy are covered. They consider anything else (hair removal, hair grafts, facial surgery, etc.) to be cosmetic, and they're not covered. If I recall, BCBS of Massachusetts covers everything, so YMMV.
If you can log into their site, all the details on the policy are right there to download. Then you can do a text search and save yourself a lot of time reading through all the legalese.
Good luck,
Stephanie
