Implications of eligibility category churn for pediatric payment in Medicaid.

ABSTRACT

OBJECTIVES: To describe the extent and implications of "churn" between different Medicaid eligibility classifications in a pediatric population (1) aged, blind, and disabled (ABD) Medicaid eligibility, determined by disability status and family income; and (2) Healthy Start Medicaid eligibility, determined by family income alone. STUDY DESIGN: As a result of a 2013 policy change, children with ABD eligibility transitioned from fee-for-service to capitated care. We used Ohio Medicaid claims data from July 2013 through June 2015 to explore the relationships among instability in eligibility category, demographics, and utilization. METHODS: To examine the potential financial effect of categorical churn, an effective capitation rate was created to capture the proportion of the maximum potential capitation rate that was realized. RESULTS: More than 20% of children exited ABD-based eligibility at least once. Switching was associated with younger age and rural residence and was not associated with healthcare use. CONCLUSIONS: Switching between eligibility categories is common and affects average capitation but not health service use.
