Introduction

In June 2026, a coalition of twenty‑five U.S. states and the District of Columbia filed a federal lawsuit against the Trump administration, contesting newly issued guidance on Medicaid work requirements. The plaintiffs argue that the federal rule narrows exemptions for medically frail individuals, threatens access to health coverage for low‑income residents, and exceeds the authority granted by Congress.

Key Issues in the Lawsuit

The Centers for Medicare & Medicaid Services (CMS) released an interim final rule that interprets the “One Big Beautiful Bill Act” work‑requirement provision. Under the law, adults aged 19‑64 must complete at least 80 hours of work, community service, or enroll in an educational program at half‑time to qualify for Medicaid, unless they qualify as medically frail. The new guidance requires a person’s condition to “significantly impair” their ability to meet these standards, a stricter test than the original statutory language.

State attorneys general contend that this narrower definition violates the Administrative Procedure Act, disregards the broad exemptions Congress intended, and imposes unconstitutional conditions on federal funding. They also note that the rule’s August 31 notification deadline leaves states insufficient time to adjust implementation plans, risking penalties for non‑compliance.

Potential Impact on Vulnerable Populations

Evidence cited in the complaint suggests that the stricter exemption could lead to a substantial loss of coverage. Studies from the Urban Institute project that 3‑7 million people could be barred from Medicaid if the rule takes effect. Past experience, such as the Arkansas work‑requirement pilot, shows that administrative hurdles can abruptly remove benefits from tens of thousands of adults without improving employment outcomes.

Advocates highlight that medically frail individuals—including those undergoing cancer treatment, living with disabilities, or battling serious mental health conditions—already face significant health challenges. Adding extensive paperwork and proof requirements may deter them from seeking needed care, undermining public health goals and increasing health disparities.

Conclusion

The lawsuit underscores a broader tension between federal policy objectives and state commitments to health equity. By challenging the CMS rule, the coalition seeks to preserve access to Medicaid for the nation’s most vulnerable citizens and to ensure that federal agencies honor the statutory protections Congress enacted. The outcome will shape how work‑requirement policies are applied across the United States and will have lasting implications for the health and well‑being of low‑income Americans.
