MC+ managed care began in 1995 in Missouri when the Division of Medical Services contracted with managed care plans to provide benefits to Medicaid participants in selected counties. The goals of the state were to improve accessibility and quality of health care services for Missouri's Medicaid participants, while reducing costs.

In 2007 SB 577 established MO HealthNet, which replaced the state Medicaid program. The details of the program continue to be defined by an Oversight Committee. Missouri’s MO HealthNet managed care currently operates in 53 counties.
