Health Insurance Coverage: What Comes After The ACA?

Abstract

The Affordable Care Act (ACA) led to the largest expansion of health insurance in the US in fifty years, bringing the uninsurance rate to its lowest recorded level in 2016. But even at that point, nearly thirty million people lacked health insurance, and millions more still struggled to afford needed medical care. Recent studies also indicate a partial erosion of the ACA's coverage gains since 2017. This article identifies the underlying causes of these problems and evaluates potential policy remedies. Topics include the slow but steady growth of state expansions of eligibility for Medicaid; new waiver approaches in Medicaid, including work requirements; high cost sharing and premium growth in both the Marketplaces and employer coverage; and proposed systemic overhauls such as Medicare for All.
