An Assessment of the Impact of Medicaid Managed Care on WIC Program Coordination With Primary Care Services

Coordination between WIC and Medicaid has been an important component to ensuring that WIC clients have access to primary care services. This study examines how increased use of managed care in the Medicaid program had affected WIC Program coordination efforts. According to the study sample, 72% of state Medicaid agencies reported that Managed Care Organizations (MCOs) were required to inform their members about WIC. About 43% of state WIC agencies sampled in the study had a formal agreement with a state Medicaid agency, generally revolving around data sharing, referrals, and provision of special metabolic infant formulas. The agreements often lacked specific details on how services should be coordinated, however. Some local WIC agencies and MCOs had implemented innovative approaches to coordination. These approaches included collocating Medicaid staff at WIC clinics, to help clients with enrollment; sharing information to promote targeted outreach efforts; helping clients identify providers and resources; and receiving funds from MCOs to cover WIC clients; transportation costs to attend WIC appointments.


Assessment of WIC Cost-Containment Practices: Final Report

The researchers examines cost-containment practices in six states, including interviews with the various stakeholders and analysis of WIC administrative data. The authors reached three major conclusions: (1) Cost-containment practices reduced average food package costs by 0.2% to 21.4%, depending on practices implemented and local conditions; (2) the cost-containment practices had few adverse outcomes for WIC participants; and (3) administrative costs of the practices were low, averaging about 1.5% of food package savings.
