Rationing is also hidden by rules.  In San Diego for example, another medicaid expansion state, Medical officially covers dental expenses.   What they don't mention is that the rules are growing ever more stringent.  No one can simply go to a dentist and have their teeth checked and cleaned.  Rules say each and every billable item must be a separate appointment and only one appointment can ever be scheduled.  The patient must actually wait a month or two for an appointment, wait a few hours in the office to have the teeth  checked, wait again to make an appointment to have the teeth cleaned, wait a month or two for the cleaning appointment, then wait a few hours in the office to have the teeth cleaned.  If any work is required, each item such as each filling, must similarly be one at a time.  You  can see how it easily would require a year to get a few fillings done, plus days and days off work while sitting in the waiting rooms.  But on paper, Medical covers dental care.
