The COVID-19 public health emergency led to federal legislation that changed the landscape of Medicaid coverage for low-income people in the United States. Policy responses led to a surge in Medicaid caseloads due to new rules preventing Medicaid disenrollment, and total Medicaid enrollment increased more from 2020 to 2023 than the net increase in insurance coverage from 2013 to 2017 following the Affordable Care Act's implementation. It is crucial for scholars and practitioners to understand the implications of this continuous coverage policy and its 2023–2024 unwinding. This paper provides an overview of Medicaid enrollment, renewal, and funding policies, highlighting how policy changed during and immediately following the acute phase of the pandemic; describes enrollment increases and their composition; reviews relevant literature; and identifies key areas for research. By examining this unprecedented period in Medicaid, we can inform future policy decisions and optimize safety net programs to be effective under a broad set of circumstances.

大流行时代医疗补助登记和资金的变化：对未来政策和研究的影响

COVID-19 公共卫生紧急事件导致联邦立法改变了美国低收入人群的医疗补助覆盖面。由于防止医疗补助退出的新规则，政策反应导致医疗补助案件量激增，并且从 2020 年到 2023 年，医疗补助总登记人数的增长超过了《平价医疗法案》实施后 2013 年到 2017 年保险覆盖范围的净增长。对于学者和从业者来说，了解这一持续覆盖政策及其 2023-2024 年取消的影响至关重要。本文概述了医疗补助的注册、续签和资助政策，重点介绍了在大流行的严重阶段期间​​和紧随其后政策如何变化；描述入学人数的增长及其构成；查阅相关文献；并确定了研究的关键领域。通过研究医疗补助这一前所未有的时期，我们可以为未来的政策决策提供信息并优化安全网计划，使其在广泛的情况下发挥作用。
