Fotolia A Kentucky judge ruled Wednesday that the state must again rebid its lucrative Medicaid contracts previously awarded to some of the nation's largest health insurers. Franklin Circuit Court Judge Phillip Shepherd blamed "irregularities" in the state's procurement process and said taken together they "severely undermine public confidence in the bidding process." This ruling puts six insurers at risk of losing their contracts with the state. However, to prevent any disruption for the more than 1 million patients covered by Kentucky Medicaid, the current awards will remain in place for now. It's unclear when the state will begin the rebidding process.
