“The implementation of the ACA Medicaid expansion in 2014 contributed to Medicaid enrollment increasing by almost 9% in FY2014 and 7% in FY2015. The growth in Medicaid enrollment slowed to 3% in FY2016, 2% in FY2017, 1% in FY2018, and 0% in FY2019.³¹ States attribute the slowing in Medicaid enrollment growth from FY2016 to FY2019 to improving economic conditions and barriers to enrollment (e.g., periodic eligibility checks between renewals) in some states.³²

“During the Coronavirus Disease 2019 (COVID-19) public health emergency period, Medicaid enrollment increased significantly. Initially, the recession at the beginning of the pandemic contributed to higher Medicaid enrollment.³³ Then, the continuous coverage requirement for the Family First Coronavirus Response Act (FFCRA; P.L. 116-127) federal medical assistance percentage (FMAP) increase became the primary driver of Medicaid enrollment increases for FY2020 through FY2023, with growth in Medicaid enrollment of 2% in FY2020, 12% in FY2021, 8% in FY2022, and 5% in FY2023.³⁴ The FFCRA FMAP increase ended December 31, 2023, and Medicaid enrollment is estimated to have decreased to 83 million in FY2024 due to the end of the continuous coverage requirement.³⁵ With the end of the continuous coverage provision, states resumed Medicaid eligibility redeterminations and disenrollments, a process referred to as Medicaid unwinding.³⁶“

“As shown in Figure 3, for calendar year 2020, Medicaid enrollment for children, nonexpansion adults, and expansion adults comprised 78% of Medicaid enrollment but accounted for 46% of Medicaid’s total benefit spending. In contrast, together individuals with disabilities and the aged populations represented less than a quarter (22%) of Medicaid enrollment but accounted for more than a half of Medicaid benefit spending (54%).³⁷ Although these statistics vary somewhat from year to year and state to state, the patterns described above generally hold true across years.”
