Abstract
This Compendium’s purpose is to inform behavioral health treatment policy by providing detailed information about each state’s approach to regulating and funding services in residential M/SUD treatment settings. The Compendium describes regulatory provisions and Medicaid policy for residential treatment in all 50 states and the District of Columbia (hereafter states) and contains links to detailed summaries of state licensure and oversight standards and, separately, state Medicaid requirements. The supporting research examined residential treatment from a legal perspective, focusing foremost on state statutes and regulations, supplemented by other documents and input from states.
