In this proposed rule, the Departments of Labor, Health and Human Services, and the Treasury propose several updates to strengthen the Mental Health Parity and Addition Equity Act of 2008 and better ensure that people seeking coverage for mental health and substance use disorder (SUD) care can access treatment as easily as people seeking coverage for medical treatments. In addition, this rule seeks public input on ways to improve the coverage of mental health and SUD benefits through other provisions of Federal law. Sixty percent of rural Americans live in mental health professional shortage areas. Non-metro adults were more likely than metro adults (43.7% vs. 34.5%) to see a general practitioner or family doctor, as opposed to a mental health specialist for depressive symptoms, and among non-metro adults with depression, fewer than 20% received treatment from a mental health professional. Comments are due by October 2, 2023.
