The department of social services shall, with the advice and approval of the Mo HealthNet oversight committee established under section 208.955, create health improvement plans for all participants in Mo HealthNet. Such health improvement plans shall include but not be limited to, risk-bearing coordinated care plans, administrative services organizations, and coordinated fee-for-service plans. Development of the plans and enrollment into such plans shall begin July 1, 2008, and shall be completed by July 1, 2011, and shall take into account the appropriateness of enrolling particular participants into the specific plans and the time line for enrollment. For risk-bearing care coordination plans and administrative services organization plans, the contract shall require that the contracted per diem be reduced or other financial penalty occur if the quality targets specified by the department are not met. For purposes of this section, “quality targets specified by the department” shall include, but not be limited to, rates at which participants whose care is being managed by such plans seek to use hospital emergency department services for nonemergency medical conditions.
