Missouri voters approved Medicaid expansion by constitutional amendment in August 2020, but the Republican-controlled legislature refused to appropriate funds for implementation. After a court order, expansion was finally implemented in October 2021 under Governor Parson. The expansion has since covered approximately 300,000 Missourians. The delayed and contested expansion is emblematic of the political fights over Medicaid in battleground states. Missouri has no state-based exchange or additional subsidy programs.
