Reducing Medicaid Churning: Extending Eligibility For Twelve Months Or To End Of Calendar Year Is Most Effective.

Medicaid churning--the constant exit and reentry of beneficiaries as their eligibility changes--has long been a problem for both Medicaid administrators and recipients. Churning will continue under the Affordable Care Act because, despite new federal rules, Medicaid eligibility will continue to be based on current monthly income. We developed a longitudinal simulation model to evaluate four policy options for modifying or extending Medicaid eligibility to reduce churning.

New estimates of gaps and transitions in health insurance.

Changes in individual or family circumstances cause many Americans to experience gaps and transitions in public and private health insurance. Using data from the 2004-2007 Survey of Income and Program Participation, this article updates earlier analyses of insurance gaps and transitions. Eighty-nine million people (one third of nonelderly Americans) were uninsured for at least 1 month during those 4 years.

Maintaining coverage, affordability, and shared responsibility when income and employment change.

The Affordable Care Act builds on existing sources of public and private health insurance, while creating new health insurance exchanges and subsidies. A potential disadvantage of preserving many sources of health insurance is the likelihood of abrupt changes in coverage or financial responsibility when individual circumstances change. This brief describes four policy challenges related to such changes: adjusting premium and cost-sharing subsidies when incomes change; coordinating eligibility for premium credits, Medicaid, and the Children's Health Insurance Program; encouraging and facilitating continuous coverage; and minimizing transitions between individual and small-business exchanges.
