A lawsuit was filed yesterday to require the state to expand its Medicaid program in accordance with the constitutional amendment supported by 53% of voters last August. The lawsuit is in response to Governor Mike Parson’s recent announcement that he had withdrawn Missouri’s Medicaid plan because lawmakers did not include the $1.9 billion estimated cost in the state budget. More than 275,000 Missourians would be eligible under expansion, which would have taken effect July 1.
