There is No Drop-Dead Date for an ACA Tax Credit Extension, But Coverage Losses Will Mount as the Clock Ticks

A discharge petition in the House paves the way for a vote on a three-year extension of the tax credits, which would provide ACA enrollees premium relief whenever it comes. While there is still time to extend the enhanced tax credits, with each passing day, more and more ACA Marketplace enrollees are going to drop their health insurance when faced with eye-popping increases in their premium payments, writes KFF’s Larry Levitt.

Data from CMS may not fully show how much the expiration of the enhanced premium tax credits has affected enrollment in the ACA Marketplaces. The extent of enrollment changes likely won’t be known until this summer, when effectuated enrollment data are typically released.

  • Kaiser Health Policy News Index: January 2015

    Feature

    The January 2015 Kaiser Health Policy News Index finds fewer than 3 in 10 Americans report paying attention to recent health policy news stories; considerably less than the shares who report following national and international news stories such as tension between the police and the mayor in New York City and the Charlie Hebdo attack in Paris.

  • Kaiser Health Tracking Poll: January 2015

    Feature

    The latest Kaiser Health Tracking Poll finds though few Americans are paying attention to the pending Supreme Court case over whether the health care law says that people in all states can get financial help to buy health insurance, most say they would want Congress and their state to act to fix potential gaps should the Supreme Court rule in favor of the plaintiffs. With a new Republican majority controlling both Houses of Congress, the public remains divided on what they would like Congress to do next with the Affordable Care Act (ACA) overall. About a third (32%) say they favor repeal, another 14 percent would like the law scaled back, 19 percent want the law to move forward as is, and nearly a quarter (23%) would like to see the law expanded.

  • Safety-Net Emergency Departments: A Look at Current Experiences and Challenges

    Issue Brief

    Safety-net hospital emergency departments (EDs) are an important part of our health care system, especially, but not only, for the uninsured and others with low income. With multiple major changes unfolding in our system today, including the development of new models of health care delivery, payment reforms, expanded insurance coverage, and increasing demand for primary care access, safety-net EDs are a sort of crucible in which these shifts and transitions can be seen playing out. To understand more about their current experiences and challenges as the Affordable Care Act (ACA) begins to takes hold, we conducted interviews with ED directors in a convenience sample of 15 safety-net hospitals around the country in June and July 2014.

  • Federal and State Standards for “Essential Community Providers” under the ACA and Implications for Women’s Health

    Issue Brief

    Safety net providers such as community health centers and family planning clinics have served a significant role in the provision of primary care and reproductive health care services to low-income and uninsured people, particularly women. The Affordable Care Act (ACA) has a provision aimed at assuring that newly-insured individuals, as well as those without coverage, can continue seeing their trusted safety net providers, also called Essential Community Providers (ECPs). This brief reviews the definition of ECPs, examines the federal and state rules that govern the extent to which plans must include these providers in their networks, identifies the variation from state to state, and discusses the particular importance of these rules and providers for women’s access to care.

  • Survey of Non-Group Health Insurance Enrollees, Wave 2

    Poll Finding

    The survey is the second in a series exploring the experiences and perceptions of people who purchase their own health insurance, the group perhaps most affected by the Affordable Care Act's reforms to the individual insurance market and tax subsidies to make such coverage more affordable. It includes people in ACA-compliant plans sold both inside and outside the federal and state marketplaces, as well as those still in non-compliant plans, which took effect prior to January 2014 and in many cases do not comply with all the law’s requirements.

  • Round 2 on the Legal Challenges to Contraceptive Coverage: Are Nonprofits “Substantially Burdened” by the “Accommodation”?

    Issue Brief

    The Affordable Care Act (ACA) requires most private health insurance plans to provide coverage for a broad range of preventive services including Food and Drug Administration (FDA) approved prescription contraceptives and services for women. Since the implementation of the ACA contraceptive coverage requirement in 2012, over 200 corporations have filed lawsuits claiming that including coverage for contraceptives or opting for an “accommodation” from the federal government violates their religious beliefs. This brief explains the legal issues raised by the nonprofit litigation and discusses the impact of the Hobby Lobby decision on the current litigation.

  • Access to Care for the Insured and Remaining Uninsured: A Look at California During Year One of ACA Implementation

    Issue Brief

    California is a bellwether state for understanding the impact of the Affordable Care Act (ACA). Much attention has been paid to enrollment in California's new coverage options, such as the Medicaid expansion (Medi-Cal) and plans sold through ACA marketplaces (Covered California), and to changes in the uninsured from 2013 to 2014. However, less is known about how this coverage has affected people’s access to care and financial security, and why others remain uninsured. This report, based on the 2014 Kaiser Survey of Low-Income Americans aims to fill this gap by comparing the newly insured, previously insured and remaining uninsured across several of these important dimensions.
