If you've given permission previously for the T's to consult, then they don't have to tell you every time they do. My pdoc and T have been given permission to talk about me - they generally tell me when they've done so, but not always. I'm fine with that, since usually it's just updates on what they're seeing with me or about med changes or something.

However, the only way you'll know for sure what's going on is to just ask your T about it.
