Sometimes they ask and have you sign some forms so they transfer over---my old doctor actually gave me a card to give to the new doctor just in case she wanted more info and they talked about me before I even met her. Technically I think some privacy laws may have been breached but he apparently didn't use my name in the initial conversation until I said I wanted to meet with her then he had to tell her who I was. But yeah if they don't normally ask that's good.
