  • 2021 Calculator – Before COVID-19 Relief

    Interactive

    The Health Insurance Marketplace Calculator, updated with 2021 premium data, provides estimates of health insurance premiums and subsidies for people purchasing insurance on their own in health insurance exchanges (or “Marketplaces”) created by the Affordable Care Act (ACA). With this calculator, you can enter your income, age, and family size to estimate your eligibility for subsidies and how much you could spend on health insurance.

  • What Happens to Medicaid Drug Policy if the ACA is Overturned?

    Issue Brief

    The repeal of the ACA could mean loss of Medicaid coverage for up to 15 million that were enrolled in the ACA Medicaid expansion group prior to the COVID-19 pandemic; however, repeal could also mean significant changes to Medicaid prescription drug policy with implications for state and federal spending for prescription drugs for non-expansion Medicaid enrollees.

  • Affordability in the ACA Marketplace Under a Proposal Like Joe Biden’s Health Plan

    Issue Brief

    This KFF analysis finds that expanding Affordable Care Act (ACA) premium subsidies like Democratic presidential nominee Joe Biden has proposed would lower the cost of Marketplace coverage for nearly all potential enrollees, including the uninsured and others currently priced out of the Marketplace. Biden's plan would, however, increase federal spending, which we do not attempt to estimate here.

    Perspective

    Published in the Jan. 19 edition of JAMA, this article from KFF Executive Vice President for Health Policy Larry Levitt lays out the major health policy challenges that will confront President-elect Biden and potential approaches to major reform.

  • ACA Open Enrollment Matters for Medicaid Coverage, Too

    Policy Watch

    President Biden’s January 28th executive order to reopen enrollment in the federal ACA Marketplace from February 15 through May 15, combined with $50 million in federal spending on outreach and education about ACA coverage options, has the potential to reach millions of people who were uninsured prior to or have lost coverage during the pandemic. As of 2019, there were 29 million non-elderly uninsured people, and the majority (57%) were eligible for financial assistance through the ACA Marketplaces (33%) or Medicaid (25%). KFF estimates indicate that nearly nine million uninsured people could be eligible for free or subsidized Marketplace coverage during the new enrollment period. Importantly, these actions to facilitate enrollment in ACA Marketplace coverage will also likely lead eligible low-income people to enroll in Medicaid coverage.
