This brief evaluates what is currently known about fraud and abuse in the Affordable Care Act (ACA) Marketplace, including how the final Marketplace Integrity and Affordability Rule and the recently enacted budget reconciliation law change existing Marketplace enrollment and eligibility standards.
Until Congress passes the reconciliation bill, Marketplace insurers will face uncertainty regarding the regulatory landscape and may find it difficult to set premiums for 2026.
A CMS rule, once finalized, is generally intended to exist permanently or until it is repealed.... This temporary implementation may preserve the potential for the reconciliation bill to generate official savings through changes to ACA marketplaces in later years (2027–2034) if enacted.
Taken together, the reconciliation bill's provisions impose additional administrative burdens on state-based marketplaces and could limit state flexibility in choosing marketplace policies and procedures.
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.
This issue brief draws from the KFF/LA Times Survey of Immigrants and other KFF analyses to highlight immigrants’ health care eligibility, healthcare use and costs, as well as their contributions to the economy and workforce.
Using data from the KFF Medicaid Enrollment and Unwinding Tracker, this analysis reports data on unwinding renewal outcomes through June 2024 and examines Medicaid enrollment changes from February 2020 through May 2024, the most recent federal enrollment data available, nationally and across states.
Section 1115 Medicaid demonstration waivers offer states an avenue to test new approaches in Medicaid that differ from what is required by federal statute, so long as the approach is likely to “promote the objectives of the Medicaid program.” As with broader Medicaid policy, the future landscape of Section 1115 waivers depends on the outcome of the November 2024 presidential election as a new administration could focus on different priorities, rescind existing guidance, or withdraw already-approved waivers. This waiver watch summarizes five key areas of difference in 1115 waiver policy and waiver approvals under the Trump and Biden-Harris administrations.
This analysis examines who was eligible for Medicare and/or Medicaid between 2002 and 2022 because they received disability benefits from one of the country's Social Security disability programs, Social Security Disability Insurance (SSDI) or Supplemental Security Income (SSI). Many who receive SSDI and SSI qualify for both Medicare and Medicaid, known as dual-eligible individuals.
issue brief provides an overview of actions by the Trump administration and Congress that are likely to affect lawfully present immigrants’ access to health coverage and care, including new restrictions on eligibility for coverage and services as well as changes in immigration enforcement and other policies.
