Three people file lawsuits against Missouri over lack of Medicaid expansion KMIZ JEFFERSON CITY, Mo. (KMIZ) Three people have sued the state for not expanding Medicaid eligibility after voters approved a constitutional amendment in August. The plaintiffs from Fenton, St. Louis and Springfield filed a lawsuit Thursday that seeks to force state leaders to expand the program to cover low-income working adults. The lawsuit names the Missouri Department of Social Services, which runs the state's Medicaid program, MO HealthNet, along with several social services officials. Gov. Mike Parson's budget included funding for Medicaid expansion. However, the Republican-controlled state legislature decided against funding the expansion. Last week Parson said the state was withdrawing its plans to expand eligibility, saying the amendment that expanded Medicaid is invalid because it didn't include a funding mechanism and the General Assembly didn't appropriate money to pay for expansion.
