This week, we reviewed updated reports issued by the Department of Health & Human Services (HHS) Centers for Medicare & Medicaid Services (CMS) on Medicaid expansion enrollment from the “December 2016 Medicaid and CHIP Application, Eligibility Determination, and Enrollment Report,” published on February 28, 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 at the beginning of 2017, representing more than 74 million Medicaid and CHIP enrollees and more than 12 million Exchange enrollees.
