About

In May 2023, Covered California, California's ACA marketplace, implemented its automatic enrollment program for individuals losing Medicaid coverage, as defined by Senate Bill 260. If individuals are found eligible for subsidized marketplace coverage, individuals will be automatically enrolled in the lowest cost silver plan available to them, but individuals must still take action to confirm their plan or pay their first month's premium. To identify whether the phone outreach is the effective outreach strategy to increase take-up in this population, Covered California implemented this intervention. The results of this evaluation will inform operational and budgeting decisions.
