Nearly a quarter (23%) of adults who say they were disenrolled from Medicaid since early 2023 report being uninsured now, finds a new KFF national survey examining how the unwinding affected enrollees.
KFF's survey examines adults who had Medicaid coverage in early 2023, just before states resumed eligibility checks and disenrollments after pandemic-era protections ended. Nearly a quarter (23%) of adults who say they were disenrolled from Medicaid since early 2023 report being uninsured now. Overall, 19% of adults who had Medicaid prior to the start of unwinding say they were disenrolled at some point in the past year.
This brief takes a closer look at the five largest publicly traded companies (also referred to as “parent” firms) operating Medicaid MCOs, which account for half of Medicaid MCO enrollment nationally. This analysis presents the latest enrollment and financial data (through the end of 2023) as well as key takeaways from the firms’ unwinding experience.
Substance use disorders contribute to a growing number of deaths, yet they often go undiagnosed and untreated. While nearly three-quarters of Medicaid enrollees with a diagnosed substance use disorder utilized some type of treatment service in 2020, medication treatment rates varied widely, being much lower for alcohol use disorder than opioid use disorder, and lower among Black enrollees and youth compared to their counterparts. Treatment rates varied considerably across states and average Medicaid spending for people with a diagnosed substance use disorder is over twice as high compared to those without a substance use disorder.
This issue brief examines well-child visit rates overall and for selected characteristics before and after the pandemic began and discusses recent state and federal policy changes that could impact children’s preventive care. More than half of children under age 21 enrolled in Medicaid or CHIP received a well-child visit in 2019, but the share fell to 48% in 2020, the start of the COVID-19 pandemic.
This issue brief examines the characteristics of the remaining uninsured population who are eligible for Medicaid or CHIP using 2022 national survey data. Despite improvements in coverage, 25.6 million nonelderly people remained uninsured in 2022.
This policy watch examines Mississippi's recent Medicaid expansion activity, what expansion could mean for residents and the economy, and key developments to watch.
This issue brief provides an overview of how Section 1115 waivers have been used to address the health-related social needs of enrollees, including a summary of recent approvals for eight states.
Ten months into the unwinding of the Medicaid continuous enrollment provision, states have conducted renewals for roughly half of all enrollees in the program. This policy watch examines three key questions to monitor as unwinding continues.
The pandemic continuous enrollment provision and other research show that continuous eligibility reduces Medicaid disenrollment and “churn” rates and helps to ensure stable coverage. As many Medicaid enrollees are currently experiencing disruptions in coverage as a result of the Medicaid unwinding, a number of states are pursuing strategies to help promote continuity of coverage, including through unwinding waivers and Section 1115 demonstration waivers. This Waiver Watch summarizes approved and pending Section 1115 waivers with continuous eligibility provisions for children and adults in Medicaid.
