States that have their own health insurance marketplace enroll a higher proportion of Medicaid-eligible residents in their Medicaid programs.

And those that rely on the federal marketplace enroll higher proportions of eligible residents in Medicaid if they let the federal marketplace determine Medicaid eligibility rather than merely refer potentially eligible individuals to their state Medicaid program.

These are among the findings in a new Commonwealth Fund report.

The “how” and the “why” are described in greater detail in the report “Streamlining Medicaid Enrollment: The Role of the Health Insurance Marketplaces and the Impact of State Policies,” which can be found here, on the Commonwealth Fund’s web site.
