Welcome to rationed health care!
With the advent of Obamacare, there is no such thing as “private insurance” for the middle class, anymore.
As a poster above noted, the OP’s policy would cover the full range of counseling, hormones, and surgery if the told their doctor that they were assigned the wrong gender at birth.
Those incredibly costly treatments have to be paid for somehow. The solutions the companies came up with (as predicted) is to ration healthcare for other conditions.
Under Obamacare, they have to pay for a woman wanting an addadicktome at the expense of a person with a bad back who wants to be able to pick up their grandchildren.
Priorities, Comrade!
