America's 24th-largest corporation Centene has agreed to pay Ohio at least $10 million to settle a lawsuit accusing the health-care giant of making off with millions of dollars meant to help the state's most vulnerable residents, The Dispatch has learned. The unusually rapid surrender by Centene on a lawsuit filed barely three months ago shows the stakes to even a $111 billion company with about 70,000 employees of Ohio's hardline action — especially a freeze on the St. Louis-based outfit's participation in a $20 billion contract to provide managed care services to 3.2 million Medicaid recipients.
