I had NJ Horizon BCBS in 2013 privately and 2014 from the exchange (AKA Obamacare) when I first transitioned and there was an exclusion of ANY transgender care services in the booklet in the mail, but like you've discovered, it's nowhere on their website. They would not cover anything at all trans related. They did finally cover some HRT (Spiro and Estridol), but only after I legally switched my gender to female. I had them years ago with another employer and then they were pretty good. Now they are horrible under the exchange and medicaid. My cis-wife on regular healthcare matters had to appeal simple tests like a followup sonogram after an abnormality found on a mammogram. You will be better off with Aetna. I'm on Health Republic now and they cover HRT, but not surgery. I'm switching to United Healthcare next year.
