Starting January 1, 2027, millions of adults who get Medicaid through the program’s expansion group will have to prove they are working, training, volunteering or in school for at least 80 hours a month to keep their coverage. The Congressional Budget Office has estimated that the requirement will touch about 18.5 million people nationwide, and separately projects that its combination of missed requirements and paperwork snags will push millions of them off the rolls entirely. For a household that depends on that coverage, the gap between staying enrolled and losing it can come down to a form that never got filed, not a shift that never got worked.
The 80-Hour Rule That Takes Effect January 1, 2027
The requirement comes from Section 71119 of the tax and spending law widely known as H.R. 1, signed on July 4, 2025. That section told the Department of Health and Human Services to publish an implementing rule by June 1, 2026, and gave states until January 1, 2027, to have the requirement running, with limited room for a documented good-faith delay.
The Centers for Medicare & Medicaid Services met that deadline, issuing an interim final rule on June 1, 2026 that spells out who is covered and how compliance gets checked. Affected adults must show at least 80 hours a month of work, job training, community service or at least half-time schooling, some combination of those activities, or monthly income at or above 80 times the federal minimum wage — $580 a month at today’s $7.25 rate. States verify status when someone applies and again at every renewal, and may check more often if they choose.

Why the Congressional Budget Office Puts the Number at Roughly 5 Million
CBO’s most recent, post-enactment look at the requirement is a supplemental cost estimate dated October 28, 2025, prepared after the bill became law. In it, the agency projects that about 2.9 million people will lose Medicaid coverage in 2034 because they don’t meet the requirement or can’t verify an exemption, plus roughly 2.8 million more who lose coverage simply because the extra application and renewal steps trip them up. Combined, CBO estimates the requirement will increase the number of people without health insurance by 5.3 million that year.
The “18.5 million subject to the requirement” figure that circulates alongside these estimates has a different, earlier source: it comes from CBO’s analysis of the House-passed version of the bill, published before Congress finalized the law’s exact text. KFF’s own tracking, last updated in late August 2026, notes CBO has not issued an updated total for how many people the enacted law’s requirement will touch — so the 18.5 million figure is best read as the order of magnitude regulators and researchers are still working from, not a fresh count of today’s enrollees.
Who Actually Has to Prove 80 Hours a Month
The rule applies to “applicable individuals”: non-pregnant adults ages 19 to 64 who are not entitled to or enrolled in Medicare and who qualify for Medicaid through the Affordable Care Act expansion group or certain related waiver programs. Congress built in a long list of carve-outs. Pregnant and postpartum women, medically frail individuals, parents and caretakers of children 13 and under or of a person with a disability, veterans with a total disability rating, members of a federally recognized tribe, former foster youth and people already meeting SNAP or TANF work rules are all exempt outright. States also have the option to grant short-term hardship exceptions for people in counties with high unemployment, in a federally declared disaster area, or who need extended medical care away from home.
A Federal Judge Has Already Let the Rule Move Forward
The requirement has already faced a court test. In late June 2026, 25 states and Washington, D.C. sued CMS, arguing the rule’s narrower definition of “medically frail” and its tight timeline went beyond what Congress wrote into the law. The states asked for a preliminary injunction to pause implementation while the case proceeds.
On July 29, 2026, U.S. District Judge Richard Stearns declined to grant it. He wrote that the states hadn’t shown the rule would cause irreparable harm, noting the federal government has agreed to reimburse 90 percent of states’ costs to build the required eligibility systems, and that the tight January 2027 deadline was set by Congress rather than CMS. The denial was without prejudice, meaning the states can renew their request, and the underlying case is still being litigated ahead of the deadline. For now, though, the rule stands: it has not been vacated, stayed or delayed.
CMS’s Own Estimate Is Lower Than the Budget Office’s
It’s worth knowing that CMS’s own interim final rule, in the regulatory analysis it published alongside it, arrives at a smaller number than CBO’s: roughly 2.3 million people losing coverage in the first year, climbing toward 3.1 to 3.3 million a year after that. The gap between the two agencies’ numbers largely comes down to how much they expect states to catch automatically through existing wage and enrollment data versus how many people will get caught by a missed notice or a renewal deadline. Both agencies agree on the mechanism — work status plus paperwork equals coverage loss — they just land on different sizes for how much of it will be paperwork. Either way, CMS’s own fact sheet is explicit that the real number will depend on implementation choices individual states haven’t finished making.
