Substance Use Disorder Policy and Care in a Time of Medicaid Change
Virtual Conference

Medicaid serves as the largest payer for substance use disorder (SUD) care treatment in the U.S. The changes from the federal “One Big Beautiful Bill Act” (OBBBA) are expected to dramatically impact the program and the people it covers. Work requirements, eligibility changes, and state budget pressures will shape care delivery and patient outcomes.
The Center for Health Economics of Treatment Interventions for Substance Use Disorder, HCV, and HIV (CHERISH), and Penn’s Leonard Davis Institute of Health Economics (Penn LDI) invite you to a virtual conference focused on strategies to preserve access in changing times. CHERISH and Penn LDI have gathered policymakers, researchers, and practitioners to explore options to help advance evidence-based SUD treatment under the new rules ahead.
