I have blue cross and what they cover from how i read it is:
M2F(F2M covers similarly but I can't recall preciecly):
SRS/GRS: 12 months HRT and Full time
Breast Augmentation: 12 months HRT and Full time
Counseling- they just cover this
Electrolysis Hair Removal required for SRS (maybe face??wording is vague), including anesthesia
HRT- blood work, pills,patch or injections
They might cover some facial feminization surgury, but I didn't recall seeing it and I'm really not interested in this or voice augmentation as I know my voice is perfectly fine and I'm pretty happy with my face atm and I would like to minimize the amount of time spent under the knife.
