Blue Cross Blue Shield has been horrible. Aside from trans related care, they keep denying my standard doctor and vision appointments even with in network doctors. As far as SRS, they only have a few surgeons in network, Marci Bowers in San Francisco and some guy that I'd never heard of in Maryland that's done 4 in the last year. They may have more but these were the 2 that they'd found for me. I have been told that Aetna and United Health Care will treat out of network doctors as if they were in network as long as there are no in network surgeons in your area. BCBS won't do this even though they are not in compliance with the Pennsylvania PPO laws so I have filed a complaint with the PA Insurance Dept. My preferred surgeon had told me that they had tried to contract with them and were denied. I was also told that there was a conference between surgeons and insurance companies to discuss coverage of trans related health care including SRS and BCBS was the only insurance company that didn't bother to show up.
