So, long story short, YES!  Each state has different regulatory requirements, so this really depends on your state.  A majority of the states have regulations around Substance Use Disorder (SUD) treatment. For Mental Health (MH) treatment, most states have regulations, but a few have no regulations for Outpatient Mental Health. Very few states have Eating Disorder (ED) specific regulations, but with Eating Disorders on the rise, lawmakers are seeking legislative answers. If we look at The Joint Commission (TJC) / CARF, they do have varied, additional standards around the populations served.
