More than a decade after its enactment, tens of millions of people nationwide rely on coverage options created through the Affordable Care Act of 2010 (ACA). The law has survived multiple court challeges at the U.S. Supreme Court and repeated attempts by Republicans in Congress to repeal it. Subsequent legislation has scaled back some aspects of the law and expanded others, including by the COVID-19 relief bill, the American Response Plan Act of 2021. This page highlights relevant analysis about the ACA and proposed and enacted changes to it..

This issue brief dissects the issues raised by the legal challenges to the Affordable Care Act’s requirement that private insurance plans include contraception as part of their coverage of preventive services for women. Over 40 for-profit corporations and over 40 nonprofit corporations have filed lawsuits claiming that the requirement to provide their employees with contraceptives violates their religious rights. On November 26, 2013, the Supreme Court agreed to hear two cases filed by for-profit corporations, Hobby Lobby and Conestoga Wood Specialties, that claim that this requirement violates their religious rights. At the crux of these cases is a question that the Supreme Court has not previously addressed: Do for-profit corporations have religious protections under the 1993 Religious Freedom Restoration Act and the First Amendment? The brief provides background on how the ACA’s contraceptive requirement works, summarizes some of the legal challenges brought by for-profit and non-profit organizations and discusses the implications of potential rulings by the Supreme Court.Issue Brief Read More

Data Note: Attempting to Measure Early Impact of the ACA through National Public Opinion Polls- A Note of Caution and What to Watch For
After the October start of open enrollment, under the Affordable Care Act, many journalists, policymakers, and the public at large are eager for early data indicating how the law is working from the perspective of potential enrollees. In particular, given the problems with Healthcare.Gov and some of the state exchange websites, many people want quantitative data about people’s experiences attempting to purchase or enroll in some sort of health insurance coverage using these mechanisms.
This Data Note raises a note of caution about the possible pitfalls of using standard national public opinion polls to make judgments about Americans’ early experiences with health plan enrollment under the ACA.
On January 1, 2014, many key provisions of the Affordable Care Act (ACA) will start to go into effect, including the expansion of Medicaid to low-income adults and the launch of new Medicaid eligibility and enrollment processes, which are designed to move toward a coordinated enrollment system across health coverage programs, including Medicaid, CHIP, and the new Health Insurance Marketplaces. Over the past year, states have made steady and significant progress preparing for these changes, but readiness varies considerably as 2014 nears, and implementation work and ongoing process improvements will continue into the foreseeable future. To provide greater insight into the status of implementation, this report provides an overview of key state Medicaid eligibility and enrollment policies slated to go into effect based on data released by the Centers for Medicare and Medicaid Services (CMS).Report Read More
To help states launch the Affordable Care Act (ACA) Medicaid expansion and efficiently enroll eligible individuals, CMS has offered states a series of facilitated enrollment options. These options include strategies, referred to as “fast track enrollment” in this issue brief, that allow states to enroll eligible individuals into coverage using data already available from their Supplemental Nutrition Assistance programs (SNAP) and/or their Medicaid or Children’s Health Insurance Program (CHIP) programs for children. This issue brief provides an overview of the new “fast track” enrollment options, including how they have been implemented, their impacts, and key lessons learned. It is based on a series of interviews with state officials in Arkansas, Illinois, Oregon and West Virginia conducted by Manatt Health Solutions and the Kaiser Commission on Medicaid and the Uninsured in October 2013.Issue Brief Read More
