This analysis examines the potential impacts on states, Medicaid enrollees, and providers of implementing a per capita cap on federal Medicaid spending, which is one proposal that has been discussed in Congress. Such a plan could decrease federal Medicaid spending by $532 billion to almost $1 trillion over a 10-year period, depending on how states respond. An estimated 15 million people could lose Medicaid coverage by 2034.
This brief examines national and state-level data on enrollment and spending for Medicare-Medicaid enrollees using the 2019 and 2020 Medicare Beneficiary Summary Files and the 2019 Transformed Medicaid Statistical Information System (T-MSIS). Spending data for Medicare includes beneficiaries in traditional Medicare only, since spending data for beneficiaries enrolled in Medicare Advantage plans are unavailable. State-level data on Medicare-Medicaid enrollment and spending are available through KFF’s State Health Facts.
This brief uses pre-pandemic data from the 2016-2019 Medical Expenditure Panel Survey (MEPS) to examine the extent to which people enroll in and retain other coverage during the 12 months following disenrollment from Medicaid/CHIP.
In this JAMA Forum column, KFF's Larry Levitt examines Medicaid's growing political importance and the potential double whammy that could hit state Medicaid programs next year with the end of the COVID-19 public health emergency and a possible simultaneous recession.
The COVID-19 pandemic has magnified pre-existing health disparities for justice-involved populations, with coronavirus infection rates among incarcerated populations higher than overall infection rates in nearly all states. Justice-involved individuals are disproportionately low-income and often have complex and/or chronic conditions, including behavioral health needs. Although the statutory inmate exclusion policy prohibits Medicaid from covering services provided during incarceration (except for inpatient services), states may take other steps to leverage Medicaid to improve continuity of care for justice-involved individuals.
More than 18 months into the COVID-19 pandemic, state Medicaid programs around the country continue to reshape policy in response to the public health emergency and at the same time advance broader initiatives and priorities, including efforts to address the social determinants of health and health equity, finds a new KFF survey.
States expect the number of people enrolled in Medicaid will increase an average of 13.2 percent across the country in state fiscal year 2015 (which runs through June in most states), showing the early effects of the first full year of Affordable Care Act implementation, according to the 14th annual 50-State Medicaid budget survey by the Kaiser Family Foundation’s Commission on Medicaid and the Uninsured (KCMU).
In his latest column for The Wall Street Journal's Think Tank, Drew Altman examines the variation among states beneath the national Affordable Care Act’s Marketplace enrollment numbers released by the U.S. Department of Health and Human Services. All previous columns by Drew Altman are available online.
A new survey from the Kaiser Family Foundation provides a comprehensive look at where states stand with their Medicaid and Children’s Health Insurance Program (CHIP) eligibility levels and enrollment, renewal and cost-sharing policies as of January 2015, one year into implementation of the Affordable Care Act’s major coverage provisions.
An estimated 10.6 million people nationally received personal help from navigators and assisters during the Affordable Care Act's first open enrollment period, finds a new Kaiser Family Foundation survey of navigators and assister programs nationally. The survey estimates that the 4,400 assister programs operating nationally had an estimated 28,000 full-time staff and volunteers, suggesting each assister would have helped more than 370 people on average during the six-month open enrollment period that ran from October 1 through March 31.
