We have BCBS insurance (Michigan) and they cover a lot of the cost of my testosterone, but not all of it. The testosterone itself costs roughly $200, but we only pay roughly $60. They also cover my therapy, psychologist & endocrinologist. We just have to pay a copay of $10 for my therapist & psychologist and $15 for my endo.
We have a pretty basic plan, but coverage on such things may vary from state to state, so you should refer to the bcbs website to make sure (I think someone already suggested this sooo yeah . . lol).
