Automated Medicaid Renewal Reminders

Summary

Rhode Island's Medicaid renewal reminder experiment addressed one of the most common causes of coverage gaps: members who are still eligible but miss renewal paperwork deadlines. The 23 percentage point improvement in on-time renewal came from a simple sequence of automated contacts that mailed notice alone did not provide. Coverage gaps are costly both for members (uninsured periods, delayed care) and for states (re-enrollment processing, emergency care costs for uninsured periods). The study has been replicated in Connecticut, Colorado, and several other states with consistent results in the 15–25 percentage point range.
