Medicaid and Exchange Enrollment Update – January 2019

This week, our In Focus section reviews updated information issued by the Department of Health & Human Services (HHS) Centers for Medicare & Medicaid Services (CMS) on Medicaid expansion enrollment from the “January 2019 Medicaid and CHIP Applications, Eligibility Determination, and Enrollment Report,” published on April 25, 2019. Additionally, we review 2019 Exchange enrollment data from the “Health Insurance Exchanges 2019 Open Enrollment Period: Final State-Level Public Use File,” published by CMS on March 25, 2019. Combined, these reports present a picture of Medicaid and Exchange enrollment in 2019, representing 72.4 million Medicaid and CHIP enrollees and 11.4 million Exchange enrollees.
