I'm sorry for the late reply, but I thought I would answer anyway in case you or anyone else is still looking for information.
I'm fairly certain that Marci Bowers would be more than willing to try and work out MassHealth with you, if you're interested in her. There are also some other surgeons who accept insurance right away -- I think Meltzer is one of them? McGinn may be another. I'm not sure. You could always try calling their offices or sending them an e-mail.
However, they may be out of network for MassHealth and you might have to dig through some paperwork and prior authorizations. As of January 01, 2015, GRS coverage was more formalized in Massachusetts plans, so you could try giving them a call to better understand what it is they do. Also, again, Marci Bowers has an assistant who is willing to work very hard to get insurances to pay for GRS. There are surgeons out there who are willing.
As for your therapist, that's a bit bleak of an attitude to take. I hope she isn't generally that way with you.
