An estimated 5.3 million more people could become uninsured as Medicaid adds work requirements

Millions of adults who currently receive Medicaid coverage face the prospect of losing it under a new federal rule that ties eligibility to monthly work or community engagement hours. The Centers for Medicare & Medicaid Services has published an interim final rule requiring non-pregnant adults ages 19 to 64 to complete 80 hours per month of qualifying activities to keep their benefits. The Congressional Budget Office scored the Medicaid provisions in H.R. 1 as producing an estimated 5.3 million additional uninsured people, a projection that now shapes the political and practical stakes for every state building a compliance system.

How 80 hours a month could strip coverage from working adults

The new requirement applies to adults enrolled through Medicaid expansion and certain Section 1115 demonstration waivers, according to the CMS fact sheet. Qualifying activities include employment, job training, education, and community service. Beneficiaries who fail to document 80 hours in a given month risk suspension or termination of their coverage, with reinstatement often contingent on catching up on paperwork and reapplying.

The design of each state’s verification system will likely determine how many people actually lose insurance. A central question is whether states will use automated data-matching, pulling wage records and employment databases to confirm hours, or instead require enrollees to self-report their activities each month. Past experiments offer a clear signal: when Arkansas briefly enforced work requirements starting in 2018, the CBO found that coverage losses stemmed primarily from administrative barriers rather than actual failure to meet work thresholds. Many people who were already working or qualified for exemptions lost coverage simply because they did not complete the paperwork or misunderstood the new rules.

States that invest in automated verification, matching Medicaid rolls against state labor department records and tax filings, should in theory record fewer erroneous terminations than states that place the reporting burden on individual beneficiaries. Employment rates alone will not explain coverage outcomes. The friction of the reporting process itself – the need for internet access, digital literacy, and time off work to deal with bureaucracy – will be the variable that separates states with modest coverage losses from those with dramatic ones.

CBO’s 5.3 million projection and what drives it

The 5.3 million figure comes from the CBO’s scoring of Medicaid-related provisions in H.R. 1, the budget reconciliation legislation that codifies community engagement requirements at the federal level. That estimate, detailed in the agency’s broader analysis of federal health programs, reflects not only people who fail to meet the 80-hour threshold but also those who drop out of the enrollment process because of confusion, lack of internet access, or inability to gather documentation. In earlier work assessing coverage dynamics, the CBO has emphasized how even small procedural hurdles can translate into large shifts in the number of insured people, a theme that runs through its discussion of Medicaid participation and related safety-net programs.

CBO baseline projections already showed Medicaid enrollment flattening after pandemic-era continuous coverage protections expired. The work requirement adds a new layer of attrition on top of that trend. The Medicaid and CHIP Payment and Access Commission, a nonpartisan congressional advisory body, has documented how earlier state-level work requirement proposals led to coverage terminations among people who were employed or otherwise exempt, reinforcing the pattern that procedural complexity, not idleness, drives most losses.

CMS’s national framework and state discretion

CMS has framed the policy as targeting “able-bodied adults” and giving states flexibility to design their own compliance infrastructure. In announcing a nationwide implementation framework, the agency described a phased approach that lets states choose among several verification models, from real-time data sharing with workforce agencies to more traditional monthly reporting portals. According to the CMS framework, states must still meet federal standards for due process, notice, and appeal rights before terminating coverage, but they retain wide latitude in deciding how beneficiaries learn about and document their hours.

That discretion means the same federal rule could look very different on the ground. A state that automatically checks wage records and presumes compliance unless data show otherwise will likely see fewer gaps in coverage than one that requires beneficiaries to log into a website every month and upload proof of hours. The former approach demands more investment in technology and data integration; the latter shifts costs and risks onto low-income adults who may have unstable work schedules, limited broadband access, or language barriers.

Who is most at risk of losing coverage

The people most vulnerable to losing Medicaid under the new rule are not those far removed from the labor market, but rather adults on the margins of low-wage work. Many juggle multiple part-time jobs with fluctuating hours that may or may not add up to 80 in a given month. Others care for children or aging relatives in arrangements that do not fit neatly into formal employment categories. While CMS allows exemptions for certain caregivers, people with disabilities, and individuals in treatment for substance use disorders, advocates warn that proving eligibility for these carve-outs can be as burdensome as documenting work hours themselves.

For safety-net clinics and hospitals, the stakes are financial as well as clinical. A sharp rise in uninsured patients would increase uncompensated care costs, particularly in rural areas where Medicaid expansion helped stabilize fragile provider networks. If CBO’s projection of 5.3 million additional uninsured people bears out, the ripple effects could include higher premiums in the individual market, greater pressure on state budgets, and renewed debates over whether work requirements ultimately save money or simply shift costs elsewhere.

As the interim final rule moves toward full implementation, states face a series of design choices that will determine whether the policy functions as a narrow work incentive or a broad coverage cut. The record from Arkansas and the cautionary numbers from CBO suggest that the margin between those outcomes will be measured less in hours worked than in forms filled out, websites navigated, and deadlines met.
