State Health Facts is a KFF project that provides free, up-to-date, and easy-to-use health data for all 50 states, the District of Columbia, and the United States. It offers data on specific types of health insurance coverage, including employer-sponsored, Medicaid, Medicare, as well as people who are uninsured by demographic characteristics, including age, race/ethnicity, work status, gender, and income. There are also data on health insurance status for a state's population overall and broken down by age, gender, and income.
The Affordable Care Act requires private insurance plans to cover recommended preventive services with no out-of-pocket charges for patients. This slate of covered services can change when the U.S. Preventive Services Task Force and other authorized groups add or modify recommendations; the federal government also periodically issues clarifications to guide health plans in their coverage.
A new issue brief from the Kaiser Family Foundation finds that Arkansas’ “private option” Medicaid expansion has helped reduce the number of uninsured and bring down uncompensated care costs while strengthening the state’s ACA marketplace.
Based on stakeholder interviews and early data on coverage, reduced uncompensated care costs, and other topics, this issue brief provides an initial look at implementation of Arkansas' Section 1115 Medicaid expansion demonstration waiver to require most adults newly eligible for Medicaid through the Affordable Care Act's Medicaid expansion to enroll in Marketplace plans.

As fall approaches, we can expect to hear more about how employers are adapting their health plans for 2016 open enrollments. One topic likely to garner a good deal of attention is how the Affordable Care Act’s high cost plan tax (HCPT), sometimes called the “Cadillac plan” tax or "Cadillac tax," is affecting employer decisions about their health benefits. The tax takes effect in 2018.
The potential of facing an HCPT assessment as soon as 2018 is encouraging employers to assess their current health benefits and consider cost reductions to avoid triggering the tax. Some employers announced that they made changes in 2014 in anticipation of the HCPT, and more are likely to do so as the implementation date gets closer.
This brief highlights how state eligibility policies for incarcerated individuals differ, based on a review of state statutes, regulations, Medicaid eligibility manuals and other Medicaid agency guidance publicly available online and Medicaid managed care contracts. Overall, state Medicaid eligibility policies for justice-involved individuals moving into and out of incarceration vary, and these policies affect if and when individuals may enroll in Medicaid and the scope of any resulting savings.
