I'm trying to determine how typical OR atypical my HMO policy is regarding appointments for mental health care.

My T gives me my next appt each time I visit - may not be the same day of the week or time, depending on his schedule. There is apparently a policy that prohibits a regular scheduled day and time. I've booked thru the online system - it lets me schedule 4 appt in a row at the same time on Wed each week. My T said I must cancel all but one.
I've always struggled with this - I want the implied contract and committment of same time next week, every week.

My son just started with a child psychologist in the community, trying to determine how to improve his school work habits. He has his own "time" - every week, same day of the week, same time.

What do you get - one at a time or same time every week?
