This policy watch examines Mississippi's recent Medicaid expansion activity, what expansion could mean for residents and the economy, and key developments to watch.
Over six months after the expiration of pandemic-era enrollment protections, at least 27 million Medicaid enrollees—or roughly one-in-three enrollees across the country—have completed their state’s eligibility renewal process for the program. Over 18 million people have had their coverage renewed and over 10 million have been disenrolled, as of November 8, 2023.
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 Visualizing Health Policy infographic looks at eligibility and coverage trends in employer-sponsored health insurance. Between 2000 and 2015, the share of workers covered by health benefits offered by their employers dropped from 63 percent to 56 percent, with some firms not offering coverage and some employees not enrolling when coverage is offered.
The Affordable Care Act (ACA) requires that Medicaid cover children with incomes up to 133 percent of the federal poverty level (FPL) ($31,322 for a family of four in 2013) as of January 2014. Today, there are “stairstep” eligibility rules for children. States must cover children under the age of six in families with income of at least 133 percent of the FPL in Medicaid while older children and teens with incomes above 100 percent of the FPL may be covered in separate state Children’s Health Insurance Programs (CHIP) or Medicaid at state option. While many states already cover children in Medicaid with income up to 133 percent FPL, due to the change in law, 21 states needed to transition some children from CHIP to Medicaid. This brief examines how the transition of children from CHIP to Medicaid will affect children and families as well as states. The brief also looks to New York and Colorado for lessons learned from the early transition of coverage.
This issue brief answers three key questions about the implications of the appeals court’s decision setting aside the Health and Human Services (HHS) Secretary’s approval of a Section 1115 Medicaid waiver amendment that included work and reporting requirements and restriction of retroactive coverage in Arkansas.
