This Health Policy 101 chapter explores Medicare, a federal health insurance program covering more than 68 million people, established in 1965 for people age 65 or older and later expanded to cover people under age 65 with long-term disabilities. In addition to detailing Medicare eligibility, coverage, and spending, the chapter examines the increased role of private plans in providing benefits and the financing challenges posed by increasing health care costs and an aging population.
Some critics of Medicaid expansion have argued that expansion diverts resources away from other groups of Medicaid enrollees, including people with disabilities and children, and that expansion enrollees are “able-bodied” implying they have minimal health care needs. However, data show that expansion states spend more per enrollee overall and on each eligibility group than non-expansion states and that nearly half of expansion enrollees have a chronic condition. This data note analyzes 2021 Medicaid claims data to compare utilization of health care services among Medicaid expansion enrollees with other Medicaid enrollees in expansion states and to compare utilization of health care services among adult Medicaid enrollees living in expansion and non-expansion states.
This Health Policy 101 chapter explores trends in health care costs in the U.S. and the factors that contribute to this spending. It also examines how health care spending varies across the population, the impact of costs on care affordability and individuals' overall financial vulnerability.
