For sixty years, Medicaid had one job: provide health insurance to people with low incomes. That changed on July 4, 2025, when the One Big Beautiful Bill Act (H.R. 1) became law and introduced the first federally mandated work requirements in the program’s history. Atrómitos has tracked this policy for five years. Evidence consistently shows that work requirements don’t increase employment. They increase paperwork, confusion, and coverage loss.
That debate is now settled by statute. The question before us is different: will implementation protect the people the law is meant to protect, or will procedural failures push millions into a coverage gap with no path back? We’ve just released a detailed policy brief examining the law, the federal guidance, and the choices still being made.
Twenty Million People, One New Condition
Under H.R. 1, adults ages 19 to 64 in the Medicaid expansion population must complete at least 80 hours per month of work, job training, education, community service, or volunteering to keep their health insurance. That requirement touches more than 20 million adults in 41 states. The Congressional Budget Office estimates the provision will reduce Medicaid spending by $326 billion over the next decade. CBO’s earlier analysis of the House-passed version projected 4.8 million people would become uninsured specifically because of work requirements. Updated coverage estimates for the enacted law have not yet been published.
Two features of the law compound the risk. First, the same population subject to work requirements will also face new semi-annual redeterminations, twice as many eligibility reviews, and an entirely new reporting obligation. Second, anyone who loses Medicaid for failing to meet or report work activities is barred from receiving Marketplace premium tax credits. They remain classified as Medicaid-eligible even after disenrollment, preventing them from obtaining subsidized private coverage. There is no fallback. Every procedural error, every piece of lost mail, every misunderstood notice becomes a path to complete underinsurance.
The Rules Aren’t Finished, but the Clock Is Running
CMS issued initial guidance in December 2025, well ahead of the statutory June 2026 deadline, covering outreach timelines, data-first verification, and the limited role of managed care organizations. However, the bulletin left the most critical questions unanswered. It does not define “serious or complex medical condition,” “medically frail,” or the scope of the family caregiver exemption. It does not clarify whether states can accept self-attestation for exemptions, a critical gap for unpaid caregivers and people whose health conditions don’t appear in claims data. And it does not explain how work requirements and the new six-month redetermination cycle should interact operationally.
An interim final rule is expected by mid-2026. If it arrives on schedule, states will have roughly seven months to translate new regulations into eligibility rules, modify IT systems, establish cross-agency data-sharing agreements, train staff, and conduct mandatory outreach, while implementing semi-annual redeterminations. Most analysts consider that timeline unrealistic, and many states are expected to seek extensions.
We’ve Seen This Before
Work requirements are not new to Medicaid. Several states tried them through Section 1115 waivers, and the track record is instructive. Arkansas spent $26.1 million on a program covering roughly 60,000 expansion enrollees that lasted nine months. During that time, 18,000 people lost coverage not because they weren’t working, but because they couldn’t navigate the reporting system. Georgia’s Pathways program has consumed $54.2 million in administrative costs, more than double what it spent on health care, while enrolling fewer than 10,000 of nearly 250,000 eligible individuals. The $200 million in federal implementation funding, about $1.96 million per state in equal-share dollars, is a fraction of what the task requires. Nebraska is now the first state to put these lessons to the test, with enforcement beginning May 1, 2026, eight months ahead of the federal deadline and before the interim final rule has been published.
Definitions Are the Battleground
The law does carve out protections: categorical exclusions for people whose Medicaid eligibility isn’t expansion-based; individual exemptions for medically frail individuals, family caregivers, former foster youth, tribal members, disabled veterans, and others; and optional short-term hardship exceptions for hospitalization, disaster areas, and high-unemployment counties. On paper, these protections are substantial. In practice, they are only as strong as the definitions that apply.
Concerning patterns are already visible. Some states are importing Social Security Administration disability standards for the “medically frail” determination, even though the statute uses broader language. Others are restricting the caregiver exemption to parents of minor children, ignoring the RAISE Family Caregiver Act’s explicit inclusion of people caring for aging family members. The standalone “serious or complex medical condition” exemption is being collapsed into disability-based categories it was designed to stand apart from. Each narrowing decision reduces the pool of protected individuals in ways the law did not require.
This Is an Action Window, Not a Waiting Period
Our policy brief lays out specific steps for healthcare providers, human services organizations, government officials, foundations, and advocacy groups. The common thread is urgency. Providers need to build documentation workflows for exemptions before the mandatory outreach period opens this summer. Human services organizations need to identify which clients qualify for protections they may not know exist. Government agencies face discretionary choices on look-back periods, reporting frequency, hardship exceptions, and self-attestation that will directly determine coverage outcomes. Foundations should prepare to fund the community infrastructure that federal dollars cannot cover. And advocacy organizations have a narrowing window to influence state-level definitions and shape the federal comment record when the interim final rule is published.
The Debate Is Over. The Work Isn’t.
The federal law is set. But implementation is where coverage is won or lost, and the decisions being made right now (in state agencies, in CMS rulemaking, in clinics and community organizations) will determine whether millions of people keep their health insurance or fall through a gap no other program can catch.
