The Kaiser Family Foundation conducted a recent survey where they interviewed Medicaid directors in all 50 states and District of Columbia to identify benefits covered for adult beneficiary programs. Federal Medicaid rules grant states flexibility to design their own Medicaid benefit packages beyond meeting core federal requirements. Required benefits specify that certain mandatory services in each state must provide adequate services in amount, duration and scope, and that coverage not vary according to an individual’s diagnosis or condition. All but four states (Illinois, Iowa, New York, and South Carolina) submitted survey responses, and the territories are not included in the 2018 data. You can view the data in the Medicaid Benefits Database and the Medicaid Behavioral Health Services Database.
