A federal work requirement written into the 2025 tax and spending law is set to reshape Medicaid eligibility for millions of adults starting January 1, 2027, and the rollout is already producing hard numbers at the state level. Forty-four states, plus the District of Columbia, must condition coverage for certain adults on proving regular work, school or volunteer activity. In California, the agency that runs the program has already put a figure on the fallout: 1.1 million people are projected to lose Medi-Cal coverage as the rule takes hold.
The 80-Hour Community Engagement Rule
The requirement comes from the reconciliation law signed in July 2025, often referred to by its short title, H.R. 1. It applies to working-age adults, generally ages 19 to 64, who qualify for Medicaid through the Affordable Care Act’s expansion group, along with certain enrollees covered under state Section 1115 waiver programs. To keep coverage, those enrollees must document at least 80 hours a month of work, job training, education or community service, or qualify for one of a defined set of exemptions. The expansion group affected covers adults with income up to 138 percent of the federal poverty level, roughly $21,597 a year for a single person under 2025 guidelines, a group that has historically had thinner financial cushion for navigating added paperwork.
The Centers for Medicare & Medicaid Services released federal guidance in June 2026 spelling out how states must verify compliance, including a narrower definition of who counts as “medically frail” for exemption purposes than some states initially expected. On June 8, 2026, the agency published the list of states and waiver populations that fall under the mandate, covering both the 41 states that have expanded Medicaid under the ACA and several non-expansion states, including Georgia, Tennessee and Wisconsin, that run 1115 waiver programs with populations subject to the rule.

California’s Numbers Behind the 1.1 Million Estimate
California’s Department of Health Care Services, which administers Medi-Cal, published its own projection in a May 2026 Local Assistance Estimate. The agency counts roughly 4.8 million Medi-Cal enrollees in the category subject to the new work requirement. Of those, about 2.2 million are expected to qualify for an exemption, leaving an estimated 1.1 million enrollees projected to lose coverage by the 2029-30 fiscal year.
Much of that projected loss traces back to paperwork rather than actual ineligibility. DHCS has flagged concern that the added documentation burden, combined with more frequent eligibility renewals required under the law, will push people off the rolls even when they meet the requirement or qualify for an exemption. Under the new law, Medi-Cal must recheck eligibility for the affected group every six months instead of annually, and the agency’s own estimate separately projects roughly 289,000 enrollees could lose coverage from that renewal change alone by June 2027, climbing toward 400,000 by 2029-30. That pattern already showed up during the pandemic-era Medicaid “unwinding,” when the large majority of enrollees who lost coverage did so for procedural reasons rather than a formal finding of ineligibility. California’s state budget office has separately estimated the added cost of implementation at roughly $1.5 billion in the current fiscal year, rising toward $9.6 billion in combined state and federal revenue effects by 2029-30, according to figures cited in the agency’s own H.R. 1 Implementation Plan.
Who Qualifies for an Exemption
Federal guidance lays out a specific list of enrollees who are excused from the work requirement. Exempt categories include pregnant enrollees and those eligible for postpartum coverage, former foster care youth, American Indians and Alaska Natives, veterans with a total disability rating, and parents or caretakers of a dependent child age 13 or younger or of a family member with a disability. Enrollees who are “medically frail,” a category that can include a disability, a substance-use disorder, a serious mental health condition or a complex medical condition, also qualify, though the CMS interim final rule narrowed how states may define and document that category compared with earlier state proposals.
People experiencing homelessness are not automatically exempt under the current federal guidance, even though many of them separately qualify under other categories, such as medical frailty or disability. Advocates in California and elsewhere have flagged that population as facing the steepest administrative hurdles in proving compliance or an exemption, since demonstrating 80 hours of monthly activity or gathering documentation is harder without a stable address or reliable mail delivery.
States Moving Ahead of the Federal Deadline
While January 1, 2027, is the deadline written into federal law for all 44 states plus DC, a handful of states are not waiting. According to KFF’s tracker of state implementation, Nebraska became the first state to begin enforcing a work requirement early, through a state plan amendment effective May 1, 2026. Montana followed with a July 1, 2026 start date, and Iowa is set to begin enforcement December 1, 2026, each ahead of the national compliance date.
Enrollees in states moving early face compliance checks sooner than the federal calendar otherwise requires, while the remaining states, including California, have until the January 2027 deadline to have systems, staff and verification processes in place. DHCS has said it plans to revise its own enrollee-loss projections later in 2026, after fully accounting for the narrower federal medical-frailty definition CMS released in June, and has indicated the update is more likely to raise than lower the 1.1 million estimate already on the books.
