Preprints with The Lancet is part of SSRN´s First Look, a place where journals identify content of interest prior to publication. Authors have opted in at submission to The Lancet family of journals to post their preprints on Preprints with The Lancet. The usual SSRN checks and a Lancet-specific check for appropriateness and transparency have been applied. Preprints available here are not Lancet publications or necessarily under review with a Lancet journal. These preprints are early stage research papers that have not been peer-reviewed. The findings should not be used for clinical or public health decision making and should not be presented to a lay audience without highlighting that they are preliminary and have not been peer-reviewed.

Background: The COVID-19 public health emergency (PHE) has caused extensive job loss and loss of employer-sponsored insurance. State Medicaid programs have experienced a related increase in enrollment during the PHE. However, the composition of enrollment and enrollee changes during the pandemic is unknown. Understanding changes in the Medicaid population during the PHE may inform policy development and identify strategies to meet the rising needs for insurance coverage during public health emergencies. This study aims to examine changes in Medicaid enrollment and population characteristics during the PHE.
Methods: A retrospective descriptive study documenting changes in Medicaid new enrollment and disenrollment, and enrollee characteristics between March and October 2020 compared to the same time period in 2019 using Full-state Medicaid populations from six states of a wide geographical region. The primary outcomes were medicaid enrollment and disenrollment during the PHE. New enrollment included persons enrolled in Medicaid between March and October 2020 who were not enrolled in January or February of 2020. Disenrollment included persons who were enrolled in March of 2020 but not enrolled in October 2020.
Results: The study included 8.50 million Medicaid enrollees in 2020 and 8.46 million in 2019. Overall, enrollment increased by 13.0% during the PHE compared to 2019, relative enrollment growth of 1.19 million. New enrollment accounted for 24.9% of the relative increase, while the remaining 75.1% was due to disenrollment. A larger proportion of new enrollment in 2020 was among adults aged 27-44 (28.3% vs 23.6%), Hispanics (34.3% vs 32.5%) and in the financial needy (44.0% vs 39.0%) category compared to 2019. Disenrollment included a larger proportion of older adults (26.1% vs 8.1%) and non-Hispanics (70.3% vs 66.4%) than in 2019.
Conclusions and Relevance: Medicaid enrollment grew considerably during the PHE, and the majority of enrollment growth was attributed to decreases in disenrollment rather than increases in new enrollment. Our results highlight the impact of COVID-19 on state health programs and can guide federal and state budgetary planning.
