  • Year Two of the ACA Coverage Expansions: On-the-Ground Experiences from Five States

    Issue Brief

    This brief provides an on-the-ground view of ACA implementation after completion of the second open enrollment period. It is based on 40 in-person interviews conducted in five states that have made different implementation choices, including three states (Colorado, Kentucky, and Washington) that have developed a State-based Marketplace and adopted the Medicaid expansion and two states (Utah and Virginia) that rely on the Federally-facilitated Marketplace (FFM) for enrollment of individuals into qualified health plans (QHPs) and that have not adopted the Medicaid expansion to date. The interviews were conducted by the Kaiser Family Foundation’s Commission on Medicaid and the Uninsured and Perry Undem Research/Communication with a range of stakeholders in each state, including Medicaid and Marketplace officials, consumer advocates, assisters, and hospital and community health center representatives, during April and May 2015. The report presents key findings related to enrollment systems; enrollment and renewal; outreach, marketing, and enrollment assistance; and access to and utilization of care. It concludes with key priorities identified by stakeholders looking ahead.

  • Kaiser Health Tracking Poll: Late June 2015 – A Special Focus On The Supreme Court Decision

    Feature

    The latest Kaiser Health Tracking Poll finds that when told that the U.S. Supreme Court ruled to keep the Affordable Care Act (ACA) as it is, allowing subsidies to be provided to low- and moderate-income people in all states regardless of who runs their Marketplace, about 6 in 10 say they approve of the decision while about a third disapprove. The King v. Burwell ruling does not appear to have had an immediate effect on the public’s overall views of the health law. Still, most Americans do not think the ACA has cleared its last big hurdle with the June 25 Supreme Court ruling; just 18 percent think the King v. Burwell case was the last major battle over the ACA, while nearly 8 in 10 think there will be more to come.
