Medicaid and Exchange Enrollment Update – May 2017

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 “May 2017 Medicaid and CHIP Application, Eligibility Determination, and Enrollment Report,” published on July 21, 2017. Additionally, we review 2017 Exchange enrollment data from the “Health Insurance Marketplaces 2017 Open Enrollment Period: Final State-Level Public Use File,” published by CMS on March 15, 2017. Combined, these reports present a picture of Medicaid and Exchange enrollment in the first half of 2017, representing nearly 75 million Medicaid and CHIP enrollees and more than 12 million Exchange enrollees.
