The health and economic effects of the pandemic have significant implications for state Medicaid programs, as more people become eligible and enroll in Medicaid at the same time that states may face declines in revenues. This brief presents current data for key economic indicators to help understand how they could affect Medicaid enrollment and spending.
At the beginning of 2024, nine months into states’ efforts to unwind the Medicaid continuous enrollment provision and reverify enrollees’ eligibility, states have completed renewals for less than half of all enrollees. To gain a better understanding of what challenges states are facing and the effects of different unwinding strategies, KFF interviewed state Medicaid officials in Arizona, Indiana, and Pennsylvania, as well as others involved, including representatives from Medicaid, managed care plans, legal aid organizations,…
Ten months into the unwinding of the Medicaid continuous enrollment provision, KFF tracking shows that states have reported outcomes for roughly half of the people expected to undergo renewals during the unwinding period. This policy watch examines the latest data and key issues to watch during the next phase of the unwinding.
Managed care is the most common delivery system for Medicaid. Most states (42, including DC) use comprehensive managed care plans to provide care to at least some of their Medicaid enrollees, according to KFF’s updated explainer. Roughly 3 out of 4 Medicaid enrollees receive care through managed care organizations and payments to these organizations account for over half of total Medicaid spending. Five publicly traded firms – Centene, UnitedHealth Group, Anthem (renamed “Elevance” in 2022),…
The states with the fastest recent growth in ACA Marketplace signups also had among the highest uninsured rates previously, as enhanced subsidies helped to make coverage more affordable for many consumers, particularly in southern states that did not expand their Medicaid programs to cover low-income adults, a new KFF analysis finds. The enhanced premium subsidies were first provided in the American Rescue Plan Act in 2021 and then extended through 2025 in the Inflation Reduction Act.…
As of September 2023, nine states are reporting data that allow for analysis of disenrollment patterns by race and ethnicity. Five states (Arizona, California, Indiana, Minnesota, and Oregon) provide data on disenrollment rates by race and ethnicity. Four states (Nevada, Oklahoma, Virginia, and Washington) report the distribution of disenrollments by race and ethnicity that can be compared to the distribution of overall Medicaid enrollment in each state by race and ethnicity.
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.
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.
Under the Patient Protection and Affordable Care Act (ACA), millions of uninsured adults and children will gain eligibility for Medicaid or health coverage through new health insurance Exchanges beginning in 2014. The law calls upon states to develop simple and streamlined processes for establishing, verifying, and updating eligibility for Medicaid, the Children's Health Insurance Program and federal subsidies for Exchange coverage. This issue brief examines how states can employ "express lane" principles in designing systems…
The health reform law provides for a national expansion of Medicaid in 2014 that will extend eligibility to millions more low-income people, primarily uninsured adults. It also requires implementation of a coordinated system for determining eligibility for Medicaid and subsidized coverage in the new health insurance exchanges. Given the expected new demands on Medicaid eligibility and enrollment systems, and continuing fiscal strains on states, the impetus to streamline and automate Medicaid systems has never been…
