The Centers for Medicare & Medicaid Services projects that its new Medicaid work requirement will strip coverage from about 2.3 million people in fiscal year 2027, a figure the agency wrote into the interim final rule it published in June. That number is not an outside estimate from an advocacy group; CMS produced it while drafting the regulation that takes effect nationwide January 1, 2027. A federal judge has already refused to block the rule, so the real question is not whether it proceeds, but why the government’s own math blames missed paperwork for more lost coverage than an outright refusal to work.
An 80-Hour Threshold Rewrites Medicaid Eligibility Starting January 1
The requirement comes from the 2025 tax and spending law that created it, and CMS’s interim final rule spells out how it works. Adults age 19 to 64 who qualify for Medicaid through the Affordable Care Act expansion group, and who are not on Medicare, must complete 80 hours a month of work, job training, community service, or at least half-time schooling to keep coverage. A combination of those activities counts too, and so does earning at least 80 times the federal minimum wage in a month, which comes to $580 in 2026.
States must check compliance twice — once when someone applies and again at each eligibility renewal — and may add more frequent checks if they choose. A state that cannot confirm an enrollee met the requirement has to send a formal notice and give that person 30 calendar days to prove compliance or an exemption before denying or ending coverage, according to the CMS fact sheet on the rule. Anyone disenrolled can reapply immediately and will be evaluated again.
Two states did not wait for the federal deadline. Nebraska began enforcing the requirement on May 1, and Montana followed on July 1, giving both states an early look at how renewal timing determines when the first coverage losses actually hit, according to CBPP’s state-by-state implementation timeline. The other 41 expansion states and the District of Columbia have until January 1, 2027, though CMS lets any state move earlier if it chooses.

The Government’s Own Math Blames Paperwork More Than Non-Compliance
CMS built its 2.3 million estimate around an assumed 15% disenrollment rate among adults subject to the new rule, and the agency’s own breakdown of that rate is the real story. About 9 percentage points come from people who genuinely fail to meet the 80-hour standard, but the other 6 points come from enrollees who cannot document compliance or prove an exemption, according to the interim final rule’s projection as reported by Medical Daily. In other words, roughly 40% of the coverage loss CMS itself expects has nothing to do with whether someone actually works.
The Congressional Budget Office, a nonpartisan scorekeeper that does not answer to CMS, puts the number far higher: roughly 5.2 million fewer Medicaid enrollees by 2034 from the work requirement alone, and close to 5.9 million once the law’s separate shift to six-month eligibility checks is counted. The two agencies are not measuring the same thing — different years, different assumptions — but even the low end of the range comes from the agency writing the rule, not from a group trying to kill it.
The paperwork math matters because more than nine in ten adults in the Medicaid expansion group already work, attend school, care for a family member, or live with a health condition that would qualify for an exemption. CMS has acknowledged that reality even while defending the rule, framing the requirement as a guardrail against fraud rather than a work incentive aimed at people who are not already working. The disenrollment risk, then, sits mostly with people who qualify but cannot prove it fast enough.
A Federal Judge Let the Rule Proceed While the Deeper Fight Continues
Twenty-five states and the District of Columbia sued CMS and the Department of Health and Human Services in late June, arguing the interim final rule narrows the definition of “medically frail” beyond what Congress intended and forces sick or disabled enrollees through unnecessary hoops to keep coverage they are legally entitled to. A federal judge in Boston heard the states’ request to pause the rule while that challenge plays out, and in Commonwealth of Massachusetts v. Oz, he declined.
U.S. District Judge Richard Stearns based the denial on the states’ failure to show they would suffer irreparable harm before the underlying case is resolved, noting that CMS has agreed to reimburse 90% of states’ costs to build the new eligibility systems. Stearns was explicit that the ruling says nothing about who ultimately wins the broader lawsuit over whether the exemption rule violates federal administrative law; it only means the January 1 deadline is not moving in the meantime.
That leaves the coverage-loss estimate standing as the working number regardless of how the medically frail dispute is eventually decided, because the disputed exemption affects a narrower slice of enrollees than the paperwork failures CMS already built into its own projection. States must notify affected members by August 31, and the agency’s own arithmetic suggests the biggest risk between now and January is not a benefits fight in court but an address CMS does not have on file.
