The purpose of this document is to present a conceptual framework to guide the development of measures of care coordination that would be both feasible to apply and meaningful in assessing the performance of Medicaid managed care organizations (MCOs) that enroll people with disabilities. Although there are no explicitly required care coordination systems now in place, some states are providing systems of coordination and doing it with existing resources. This document presents a structure for defining and measuring good care coordination for states that have systems and want to measure them, and for those who may wish to implement systems in the future.
