This week, our In Focus section reviews updated reports issued by the Department of Health and Human Services (HHS) on Medicaid expansion enrollment from “Medicaid & CHIP: December 2015 Monthly Applications, Eligibility Determinations, and Enrollment Report,” published on February 29, 2016. Additionally, we review Exchange enrollment from the HHS Office of the Assistant Secretary for Planning and Evaluation (ASPE) Issue Brief, “Health Insurance Marketplace 2016 Open Enrollment Period: January 2016 Enrollment Report.” Combined, these reports present a picture of Medicaid and Exchange enrollment at the beginning of 2016.
