Recently there have been declines in Medicaid and CHIP enrollment, reversing a previous trend of increases following implementation of the ACA. Experiences in some states suggest that renewal process requirements and growing use of periodic eligibility checks may be contributing to disenrollment among people who are still eligible for coverage as well as increased churn in coverage. This brief reviews current rules and state processes related to renewal and periodic eligibility reviews and discusses potential process issues that may be contributing to Medicaid and CHIP enrollment declines.
Millions of people are losing jobs due to the coronavirus pandemic and seeking financial assistance through Unemployment Insurance (UI) programs. While UI can provide an important source of temporary assistance for many people losing jobs, there have been reports of major challenges accessing UI benefits. Over time, states have significantly streamlined Medicaid and the Children’s Health Insurance Program (CHIP) application and enrollment processes to overcome many similar challenges to connect eligible people to health insurance coverage. As such, previous experience enrolling individuals into Medicaid and CHIP can provide lessons learned that could help inform efforts to connect people to UI. This brief summarizes some key lessons learned and discusses how states could potentially apply these lessons to UI.

Churn has implications for access to care as well as administrative costs faced by states.
