No, you are not a healthcare provider so you are not covered when overhearing someone else's information (that person signed a waiver that her psychologist/health insurance company that they could share her information). It's not like you can "use" it for anything; you do not know the other person and have no interaction with her or with anyone she might interact with. Too, it was sloppy of the psychologist to not close his door but not criminal anymore than it was criminal for you to pay attention/listen in to someone else's conversation. If you knew the person the psychologist was talking about you would have immediately gotten up, gone to his doorway and either shut his door or interrupted him and told him to shut his door as his client's information was being compromised. But I can get almost as much information from a casual search on the Internet (was going to say "phone book" but no one uses them anymore :-) There was no "intent" there. HIPPA protects against intent.
