Federal Judge Refuses to Block Medicaid Work Requirements Rule Before 2027 Deadline

U.S. District Judge Richard Stearns on July 30 refused to halt enforcement of the Trump administration's rule tightening Medicaid work requirements, rejecting a preliminary injunction request from a coalition of Democratic-led states and leaving the regulation in effect while their lawsuit proceeds in Boston federal court.

Stearns issued a six page decision finding the states had not shown the irreparable harm needed for emergency relief, Bloomberg Law and STAT News reported. The order keeps the Centers for Medicare and Medicaid Services on track to require enforcement of the new eligibility regime by January 1, 2027, a statutory deadline written into last year's budget reconciliation law, H.R. 1, which Republicans branded the One Big Beautiful Bill Act.

Ruling Turns on Reimbursable Costs

Money sat at the center of the decision. According to Becker's Payer Issues, Stearns concluded that the compliance costs the states cited are largely recoverable because the federal government has committed to reimburse 90 percent of implementation expenses. Emergency relief requires harm that cannot be undone later, and recoverable administrative spending, in the court's view, did not clear that bar.

On the remaining 10 percent of costs, the states' core complaint concerned the compressed compliance schedule. Stearns was unmoved, writing that "this timeline was set by Congress in H.R. 1, not by CMS in the challenged IFR," STAT News reported. Because Congress fixed the January 2027 date in statute, the judge reasoned, blocking the agency's interim final rule would not relieve states of the underlying deadline.

Stearns also flagged the limits of his order. The denial "is not a reflection or anticipation of its ultimate views on the merits of the underlying litigation," he wrote, according to Becker's, while acknowledging that the case presents "difficult issues regarding the scope of Congress's delegation" to the agency.

Rule Narrows Medically Frail Exemption

Interim final rule CMS-2454-IFC, issued by CMS on June 1 and published in the Federal Register on June 3, implements the Medicaid work requirements Congress enacted in 2025. Under the statute, adults ages 19 to 64 covered through Medicaid expansion must document 80 hours a month of work, community service, job training, or at least half time school enrollment, or show monthly household income of at least 580 dollars, the equivalent of 80 hours at the federal minimum wage.

Qualifying activities span paid employment, self employment, unpaid work for private entities, community service through nonprofits or public agencies, and government training programs, and enrollees may combine categories to reach the 80 hour threshold, according to an analysis by Georgetown University's Center for Children and Families. Congress wrote nine categorical exclusions into the law, covering pregnant and postpartum enrollees, former foster youth under age 26, veterans with total service connected disability ratings, people in active substance use treatment, caretakers of children age 13 and younger, and people who are medically frail, among others. The states' complaint targets how CMS translated that last category.

According to the Georgetown analysis, the rule adds a test found nowhere in the statute: a qualifying condition must also "significantly impair the individual's ability to comply" with the work requirement. Verification rules then tighten over time. States may accept an enrollee's sworn statement of medical frailty during 2027, but beginning January 1, 2028, self attestation is limited to once per enrollment period, with documentation required afterward when reasonably available. States must also apply a 12 month adjudicated claims lookback when verifying conditions, and optional hardship exceptions key off prior months rather than current circumstances.

States Argued CMS Exceeded Congress

Filed June 29 in the U.S. District Court for the District of Massachusetts, the lawsuit, Commonwealth of Massachusetts v. Oz, names CMS Administrator Mehmet Oz, Health and Human Services Secretary Robert F. Kennedy Jr., and their agencies as defendants. According to the Civil Rights Litigation Clearinghouse, the plaintiffs include more than 20 state attorneys general, the District of Columbia, and the governors of Kentucky and Pennsylvania; Becker's counted 25 states plus the District among the challengers. Massachusetts anchors the coalition, and the Boston Globe reported in June that five New England states joined the suit against the work requirement.

The complaint alleges the rule is contrary to law and arbitrary and capricious under the Administrative Procedure Act. In the states' telling, Congress defined who is exempt from Medicaid work requirements, and CMS shrank those protections by adding the impairment test, restricting self attestation, and imposing lookback periods the statute never mentions. Colorado Attorney General Phil Weiser, announcing his state's participation, accused the administration of unlawful implementation of the requirements for medically frail individuals.

Leadership of the multistate coalition runs through three offices. Massachusetts Attorney General Andrea Joy Campbell is jointly leading the litigation with California Attorney General Rob Bonta and New Jersey Attorney General Jennifer Davenport, Fierce Healthcare reported. "The Trump Administration's attempt to impose new, burdensome requirements on Medicaid recipients threatens access to healthcare for our most vulnerable residents and families," Campbell said in announcing the suit. Her office described the interim final rule as an "abrupt change" that, left standing, would make it significantly harder for vulnerable people to qualify for exclusions and to keep their coverage.

Prior state experiments inform the stakes. The Georgetown analysis notes that earlier reporting regimes produced significant coverage losses driven by confusion and paperwork burdens among people who remained eligible, a dynamic the states say the new verification architecture will repeat at national scale. Coverage of the ruling has already focused on the human consequences of the narrowed exemption: IBTimes UK reported that the stricter framework can force seriously ill enrollees, including cancer patients, to document that they are too sick to work in order to keep coverage.

Lessons From the Arkansas Rollout

Arkansas remains the only state to have fully enforced Medicaid work requirements before now, and its record supplies ammunition to both camps. CMS approved the state's waiver in March 2018, reporting obligations began that June, and by the end of December 18,164 enrollees had lost coverage, roughly one in four of those subject to the mandate, according to Georgetown University's Center for Children and Families.

Research published afterward cut against the policy's stated goals. A New England Journal of Medicine study of the program's first year found that more than 95 percent of the target population appeared to satisfy the requirement or qualify for an exemption, yet thousands lost coverage anyway, an outcome the authors traced to widespread confusion and low awareness of the reporting rules rather than to any failure to work.

Courts ultimately halted the experiment. In Gresham v. Azar, a federal district judge found the approval of the Arkansas program arbitrary and capricious, and a unanimous D.C. Circuit panel affirmed in February 2020 on the ground that the agency never adequately weighed coverage loss, AJMC reported at the time. That earlier fight concerned state waivers granted at agency discretion; the 2025 statute makes the mandate national, which is why the present dispute turns on how far CMS may go in filling statutory gaps rather than on whether work rules are permissible at all.

Coverage Projections Reach Into the Millions

National exposure dwarfs the Arkansas numbers. Congressional Budget Office scoring of the reconciliation law's work provision projects 326 billion dollars in reduced federal Medicaid spending over ten years and 5.3 million additional uninsured people, the largest coverage effect of any Medicaid change in the statute, according to a KFF analysis of the 2025 law. Urban Institute modelers put potential losses higher still, estimating that between 5.5 million and 6.3 million expansion enrollees ages 19 to 64 would lose federally funded coverage under full implementation, per the same KFF review, which noted that CBO's work requirement estimates have generally run below those of the Urban Institute, the Center on Budget and Policy Priorities, and Brookings.

Scale magnifies every design choice in the rule. Roughly 67 million Americans are enrolled in Medicaid, Newsweek reported in its coverage of the Stearns decision, and researchers who study administrative burden expect paperwork rather than joblessness to drive most disenrollment. "Whenever you require people to deal with burdens and red tape, a lot of people are going to lose benefits," University of Missouri public policy professor Jake Haselswerdt told Newsweek after the ruling.

State Eligibility Systems Face a Compressed Build

Survey data shows how much construction remains. In a KFF survey of state Medicaid programs, nearly every responding state described significant eligibility system changes still ahead, with special complications for states that run integrated Medicaid and SNAP platforms, where a single redesign touches multiple benefit programs at once. Several states reported being midway through multiyear IT modernization projects that must now absorb the work requirement build simultaneously, and respondents repeatedly cited limited staff capacity and tight budgets as compounding constraints.

Verification plans lean heavily on automation. Most states told KFF they intend to add compliance questions to applications and renewals and to check hours against existing data sources, including wage records, SNAP participation, and state unemployment files, before asking enrollees for documentation. Most also plan to modify systems through existing vendors because the calendar leaves no time to procure new ones. States warned that locking in designs before final federal guidance arrives raises costs and the risk of rework, the same compressed schedule complaint now sitting at the center of the Massachusetts case over Medicaid work requirements.

Deadline Pressure Builds Toward January 2027

Near term obligations continue to accumulate. STAT News reported that states must notify affected beneficiaries by August 31, and the statute requires full enforcement of Medicaid work requirements by January 1, 2027. The mandate reaches expansion populations in 41 states, according to the Georgetown analysis, forcing eligibility system rebuilds, staff training, and outreach campaigns on a schedule state officials have called unworkable in court filings.

Relief from Washington looks limited. CMS has indicated it expects to approve only about two of roughly ten anticipated good faith extension requests, each capped at six months with quarterly reapplication, per the Georgetown analysis. That posture leaves most states building toward the January date regardless of how the litigation resolves.

Litigation Path From Here

Stearns denied the injunction without prejudice, meaning the states can renew the request if the case stalls or circumstances change. STAT News reported that the judge intends to schedule hearings on the merits before the January 1 enforcement date, an aggressive calendar for administrative litigation of this scope.

Practical continuity is the immediate effect: states must keep standing up compliance systems for Medicaid work requirements even as they argue the rule authorizing key pieces of that machinery is invalid. A merits ruling striking the medically frail provisions would force CMS to rewrite portions of the rule with little runway before enforcement begins. A government win would cement the stricter exemption framework through the 2027 rollout.

Either outcome offers an early measure of how much room agencies have in implementing the health provisions of H.R. 1. Both sides retain appellate options in the First Circuit, and with the statutory clock running, the losing party at the merits stage will face pressure to seek expedited review. For millions of expansion enrollees whose coverage will soon depend on documenting 80 hours a month, the first courtroom test of Medicaid work requirements ended without a pause button.
