EV, I'm in the same situation. My ta psychologist, so I don't think he has to consult with anyone. He has told me that he's discussed me with others and not used my name, though. However, I think many t's (depending on the license they have) do have to consult with someone for dx, treatment plan, etc. This is only my understanding from talking with others, though. So, you can take it with a grain, because I don't always understand.
Even if your t does have to report, it doesn't mean that it's too your psychiatrist. I would ask t about that. I'm sure they'd tell you.
good luck!
