  • Health Reform and the Art of Federalism

    Perspective

    The U.S. Department of Health and Human Services (HHS) recently announced significant changes to the premiums charged in the Pre-existing Condition Insurance Plan (PCIP), aka the "high risk pool" created by the Affordable Care Act. Premiums will now be up to 40% lower depending on the state (in some states the cost to enrollees is unchanged), and application procedures will be eased. The PCIP plans provide coverage for people who cannot buy coverage in the…

  • An Employer Health Benefits Balance Sheet

    Perspective

    There seems to be growing interest in the question of how many employers will keep offering coverage to their full-time employees once the Affordable Care Act (ACA) is fully implemented in 2014, or instead will choose to stop offering coverage and pay a penalty. While there is some good analysis and plenty of conjecture, it is impossible to predict with any certainty how employers will react at this moment because some of the key rules…

  • CBO’s Estimate of Repealing Exchange Grants: The Importance of Being Effective

    Perspective

    The Congressional Budget Office (CBO) recently released an analysis of a bill that would repeal grants to states under the health reform law to help them establish health insurance purchasing exchanges. Not surprisingly, CBO finds that the bill would reduce federal spending due to the fact that expected grants won't be provided, to the tune of $1.9 billion over ten years. But, that's not the biggest effect on the federal budget. CBO also finds that…

  • Who Will be the H&R Block and TurboTax for Health Insurance?

    Perspective

    There's been quite a bit of focus lately insofar as these issues go, anyway on health insurance agents and brokers (sometimes known in the industry as "producers"). They are pushing legislation that has been introduced in Congress and is now being studied by the National Association of Insurance Commissioners that would exempt agent and broker commissions for health insurance from minimum medical loss ratio (MLR) thresholds established in the health reform law.

  • August Kaiser Health Tracking Poll: The Uninsured and the Health Reform Law

    Perspective

    The August Kaiser Health Tracking Poll finds that even though 32 million uninsured Americans will gain health insurance under the ACA, only about half of non-elderly Americans currently without coverage say they are familiar with the chief components in the law designed to achieve this goal. Fifty-two percent of the uninsured say they are aware the law will provide subsidies to help low- and moderate-income people without insurance purchase it. And 47 percent are aware that…

  • Pop Quiz: Assessing Americans’ Familiarity with the Health Care Law

    Perspective

    Based on the December Kaiser Health Tracking Poll, the latest KFF data note explores Americans’ awareness of what the Affordable Care Act (ACA) will do. As the 112th Congress prepared to take office and the discussion of repeal was on the rise, we 'quizzed' Americans on whether they thought a series of ten provisions were included in the new law, ranging from five items that are part of the law (i.e., Medicaid expansion, changes in…

  • KFF February Health Tracking Poll: Nearly Half Confused About Status of the Health Reform Law

    Perspective

    In the latest Kaiser Health Tracking Poll, nearly half of Americans say they are confused about the status of the health reform law. While 52 percent of the public is aware that health reform is still law, 22 percent think the law has been repealed and is no longer law and another 26 percent are not sure. Americans are still divided about what they want lawmakers to do on health reform. Three in ten say…

  • KFF/Harvard Survey on Public’s Health Care Agenda for the 112th Congress Finds An Uptick in Public Opposition to Health Reform As GOP Ramped Up Repeal Campaign

    Perspective

    Though the public remains divided on health reform overall, according to a new survey jointly conducted by the Kaiser Family Foundation and Harvard School of Public Health, opposition to the new law ticked upward in January from 41 percent to 50 percent as Republicans ramped up efforts to repeal it. The survey also showed that there is no groundswell of public support for overturning the law, with 47 percent wanting to either expand the law…

  • What is a Mini-Med Plan?

    Perspective

    One of the early insurance market changes in the Affordable Care Act (ACA) phases out caps that some insurance plans impose on the annual dollar amount of benefits they will cover. Plans issued or renewed after September 23, 2010 cannot have annual limits of less than $750,000, and the threshold goes up to $1.25 million in 2011. Annual dollar limits of any kind are prohibited starting in 2014. The federal government has issued waivers from…

  • Kaiser November Tracking Poll Finds Health Care a Factor in Congressional Election, But Not a Dominant One

    Perspective

    This month’s Kaiser Health Tracking Poll, conducted during the four days following the mid-term election, asked voters in an open-ended question to name in their own words the biggest factors influencing their vote for Congress, and found that health care was a factor, but not a dominant one. Among all voters, the factor mentioned most often was the economy/jobs (29%). The next two most mentioned factors were party preference (25%) and views of the candidates…
