Second Analysis Finds Modest Shifts in Medicare Advantage Plan Options When Medicare's 2016 open enrollment begins Oct. 15, current enrollees in stand-alone Medicare Part D plans are projected to face an average 13 percent increase in premiums if they remain in their current plan for 2016, a new analysis finds.
Medicaid is the nation’s main public health insurance program for people with low incomes, and it is the single largest source of health coverage in the U.S., covering nearly 70 million Americans. Medicaid also finances 16% of total personal health spending in the nation. States design and administer their own Medicaid programs within federal requirements, and states and the federal government finance the program jointly. As a major payer, Medicaid is a core source of financing for safety-net hospitals and health centers that serve low-income communities, including many of the uninsured. It is also the main source of coverage and financing for both nursing home and community-based long-term care.
Safety-net hospital emergency departments (EDs) are an important part of our health care system, especially, but not only, for the uninsured and others with low income. With multiple major changes unfolding in our system today, including the development of new models of health care delivery, payment reforms, expanded insurance coverage, and increasing demand for primary care access, safety-net EDs are a sort of crucible in which these shifts and transitions can be seen playing out. To understand more about their current experiences and challenges as the Affordable Care Act (ACA) begins to takes hold, we conducted interviews with ED directors in a convenience sample of 15 safety-net hospitals around the country in June and July 2014.
This slideshow gives a basic overview of the Medicaid program, including how it is financed, whom it covers and the role of Medicaid under the Affordable Care Act (ACA).
This brief examines the oral health status of low-income adults, the dental benefits covered by state Medicaid programs, and low-income adults’ access to dental care today.
This brief analyzes data from the 2014 Consumer Expenditure survey to measure the impact of insurance on the health care spending and budgets of low-income households.
This brief highlights low-income workers and the impact of ACA coverage expansions on this population. Low-income workers may not have access to jobs that provide full-time, full-year employment or jobs with comprehensive benefit packages, including health insurance. Medicaid plays an important role in providing health coverage for low-income workers, and coverage expansions implemented under the ACA have produced substantial coverage gains for low-income workers and a corresponding reduction in the uninsured. However, low-income workers in non-expansion states with incomes too high for Medicaid but too low for subsidies in the Marketplace do not have an affordable coverage option and will likely remain uninsured.
Using findings from the 2014 Kaiser Survey of Low-Income Americans and the ACA, this report focuses on the low- and middle-income newly insured in 2014, comparing them to the previously insured and they uninsured.
