More than a decade after its enactment, the future of the Affordable Care Act (ACA) remains uncertain as the U.S. Supreme Court takes up another challenge to the law’s constitutionality in California v. Texas (known as Texas v. U.S. in the lower courts). Oral argument is scheduled for Tuesday, November 10, 2020.
The ACA remains in effect while the litigation is pending. However, if all or most of the law ultimately is struck down, it will have complex and far-reaching consequences for the nation’s health care system, affecting nearly everyone in some way.

Declines in Uncompensated Care Costs for The Uninsured under the ACA and Implications of Recent Growth in the Uninsured Rate
The increase in the uninsured rate in recent years, as well as loss of coverage during the pandemic, has led to attention on the consequences of being uninsured. The need for medical care to test, treat, or prevent COVID-19 has also highlighted the potential consequences of uncompensated care for uninsured people. Uncompensated care costs occur because, although people who are uninsured use less care than people with coverage, most who are uninsured have limited income or resources and cannot afford the high cost of medical care, if and when they do need or use health care.
This brief estimates the level of public funding that was paid to help offset providers’ uncompensated care costs for the uninsured in 2017. To conduct the analysis, we rely on several secondary data sources including government budget appropriations and expenditure data for major public programs that provided funds to cover the cost of care for the uninsured, as well as analyses of secondary data sources completed by others.
