“The implementation of the ACA Medicaid expansion in 2014 contributed to Medicaid enrollment increasing by an estimated 8.8% in FY2014 and 7.2% in FY2015. The growth in Medicaid enrollment is estimated to have slowed to 3.3% in FY2016, 1.7% in FY2017, 0.7% in FY2018, and 0.0% in FY2019.32 States attribute the slowing in Medicaid enrollment growth from FY2016- FY2019 to improving economic conditions and barriers to enrollment (e.g., periodic eligibility checks between renewals) in some states.33
“During the Coronavirus Disease 2019 (COVID-19) public health emergency period, Medicaid enrollment has increased by 1.9% in FY2020 and 14.6% in FY2021.34 Initially, the recession at the beginning of the pandemic increased the rate of growth for Medicaid enrollment.35 Since then, the continuous coverage requirement for the Family First Coronavirus Response Act (FFCRA; P.L. 116-127) federal medical assistance percentage (FMAP) increase has driven the Medicaid enrollment increases (see the “Federal Share” for more information about FMAP and this increase).36“
