This week, our In Focus section reviews updated reports issued by the U.S. Department of Health and Human Services (HHS) on Medicaid expansion enrollment from “Medicaid & CHIP: March 2016 Monthly Applications, Eligibility Determinations, and Enrollment Report,” published on May 25, 2016. Additionally, we review Exchange enrollment from the HHS Office of the Assistant Secretary for Planning and Evaluation (ASPE) Issue Brief, “Addendum to the Health Insurance Marketplace 2016 Open Enrollment Period: Final Enrollment Report.” Combined, these reports present a picture of Medicaid and Exchange enrollment at the end of the first quarter of 2016.
