Medicaid and Exchange Enrollment Update – 2017-18

This week, our In Focus section reviews updated reports issued by the Department of Health & Human Services (HHS) Centers for Medicare & Medicaid Services (CMS) on Medicaid expansion enrollment from the “December 2017 Medicaid and CHIP Application, Eligibility Determination, and Enrollment Report,” published on April 30, 2018. Additionally, we review 2018 Exchange enrollment data from the “Health Insurance Marketplaces 2018 Open Enrollment Period: Final State-Level Public Use File,” published by CMS on April 3, 2018. Combined, these reports present a picture of Medicaid and Exchange enrollment at the beginning of 2018, representing more than 74 million Medicaid and CHIP enrollees and nearly 12 million Exchange enrollees.
