The expansion of Medicaid in Missouri was approved by voters in Missouri through the passage of a constitutional amendment in August 2020, implemented in July 2021. Enrollment in the Adult Expansion Group (AEG) grew to over 350,000 at its peak in Missouri in June 2023, but at the same time applications for coverage and enrollment counts of persons with disabilities dropped significantly. This brief explores the changes in applications for Medicaid coverage by persons with disabilities, and enrollment under the disability category, with analysis of the implications for the budgetary costs for Missouri’s general revenue budget.
