Medicaid Work Rules Hit in 2027 as Employer Health Costs Surge

Two cost pressures arrive together

The biggest changes to Medicaid in a decade take effect nationwide in January 2027. In the same month, employers expect their largest jump in health benefit costs in more than 20 years. These are separate developments, but they are connected. Medicaid cuts remove insured patients from the system, hospitals lose revenue, and the gap between what care costs and what gets paid grows. The question for the next two years is who pays to close that gap: hospitals, patients, employers or workers. The likely answer is some of each, though not in equal shares.

What changes in Medicaid, and when

The One Big Beautiful Bill Act (OBBBA), signed in July 2025, requires adults covered through the Affordable Care Act's Medicaid expansion to log at least 80 hours a month of work, community service, job training or half-time school. People with an exemption are excluded12. Exemptions include pregnancy, medical frailty, caring for a disabled relative and being the parent of a child under 142. People applying for the first time have to show they meet the rule before they can enroll2. The requirement covers Washington, D.C., and the 40 expansion states. It also reaches some low-income adults in Georgia and Wisconsin and certain parents in Tennessee6.

The national deadline is January 1, 2027, but some states have started early. Nebraska began enforcing the rule on May 1, 2026. Montana and Arkansas followed in July, and Iowa is scheduled for December4. Arkansas is phasing in more softly and is holding off on disenrolling people who don't comply until January 20279. States can also ask federal regulators for more time. A state that shows a good-faith effort can delay the requirement until the end of 20287.

The work rule gets most of the attention, but several quieter changes may matter just as much:

• Six-month renewals. Starting in 2027, expansion adults must have their eligibility rechecked every six months instead of once a year610.
• Shorter retroactive coverage. Medicaid currently pays some bills from before a person applied. From January 2027, that backward-looking coverage is capped at one month for expansion enrollees and two months for others67.
• Immigrant eligibility. New limits on federal Medicaid funding for several groups of noncitizens begin in October 202610.
• Less federal funding for states. New rules reduce federal Medicaid money to most states starting in October 20276, and limits on the provider taxes states use to fund their share of the program begin in fiscal 20272.
• Cost-sharing. Expansion enrollees with incomes above the poverty line will owe more out of pocket starting in October 202836.

The savings are back-loaded. Federal Medicaid spending falls by about $16.8 billion in fiscal 2026, $46.7 billion in fiscal 2027 and $165 billion by fiscal 2034, according to the year-by-year figures9. The Congressional Budget Office (CBO) puts total Medicaid cuts at about $990 billion over ten years and expects 7.5 million more people to be uninsured in 203410.

How many people lose coverage depends on whose estimate you use

Estimates of coverage losses vary widely. CBO expects the work requirement alone to cut about 5.2 million adults from Medicaid by 20341. CBO also counts 4.8 million people who end up uninsured as a direct result4. The Centers for Medicare & Medicaid Services (CMS), which runs the program, projects enrollment drops of about 2.3 million in fiscal 2027 and 3.1 million to 3.3 million in later years9. Outside groups go much higher. One analysis puts losses at 10 million to 15 million people2, and an advocacy group for older Americans uses 11 million8. The analysts often use different definitions, timeframes and assumptions about how well states share data, so the numbers are not directly comparable.

On the most important point, the estimates largely agree: most people who lose coverage will not be people who refuse to work. CBO's model splits the work-rule losses into about 2.9 million people who don't meet the requirement or qualify for an exemption and another 2.8 million who are dropped because the extra paperwork becomes a barrier9. For six-month renewals, CBO expects about 70% of the people who lose coverage to be dropped for procedural reasons and only about 30% to actually be ineligible9. Arkansas tried work requirements in 2018. About 18,000 adults lost coverage, and a two-year follow-up found no increase in employment9.

The likeliest outcome is that 2027 looks like a paperwork failure more than a test of who works. The early-enforcing states will show how quickly that happens.

Hospitals take the first hit

Hospitals are where coverage losses become costs. They must treat anyone who comes to the emergency room, so when patients lose insurance, hospitals absorb more unpaid care12. The California Hospital Association expects the state's uncompensated care to rise from $2 billion to $4 billion a year. More than half of California's hospitals already lose money on operations12.

National projections that are widely cited need careful reading. Commonwealth Fund modeling found that safety-net hospitals could see operating margins fall by an average of 56%, and that uncompensated care costs would rise by $14.3 billion. That model assumed every state ends its Medicaid expansion in 2026, which the law does not require11. An Urban Institute report found an $80 billion drop in health spending and a rise of nearly $19 billion in uncompensated care14. It also modeled states dropping expansion entirely17. Both studies show how exposed hospitals are. Neither is a forecast of what will happen in 2027.

Other pressures are already in place. Long-delayed cuts to Medicaid's Disproportionate Share Hospital payments, which help hospitals that serve many low-income patients, took effect in October 202520. The law includes a $50 billion Rural Health Transformation Program, but Harvard researchers say it cannot replace the role insurance plays in keeping hospitals solvent20. They also found that many financially distressed safety-net hospitals are in cities, not just rural areas. About half of the safety-net or critical-access hospitals in financial distress are urban20. Families USA estimates that 55 more rural hospitals could be at risk of closing19.

When hospitals cut costs, everyone in the community is affected. Hospitals may lay off staff or close expensive services such as labor and delivery, whatever patients' insurance status1216.

What it means for patients' bills

The shorter retroactive coverage window is easy to miss but directly affects patients. A hospital bill from before those one- or two-month windows may stay unpaid even if the patient qualifies for Medicaid on the day they apply10. In the past, people often signed up for Medicaid after an emergency, and that coverage absorbed the bill. From 2027, more of those bills will go to patients' collections accounts or onto hospitals' books. People who lose Medicaid for failing the work rule are also generally blocked from subsidized marketplace plans, which leaves them with no affordable option5.

Employers face a separate surge

Employer costs are rising quickly for reasons that have little to do with Medicaid. Marsh, the benefits consultant formerly called Mercer, surveyed about 1,800 employers. It projects an 8.2% rise in per-employee costs for 2027 even after cost-cutting, and about 11% without it. That would be the biggest increase since 20032329. Other consultants project similar or larger increases:

• WTW: 11.1%22
• Aon: 9.5%, pushing average costs above $19,000 per employee25
• Business Group on Health: a 9.2% median, falling to 8% after benefit changes23

The main causes are hospital prices, provider consolidation, new cancer therapies and GLP-1 drugs such as those used for weight loss. Marsh says GLP-1 drugs alone add about one percentage point2829. Marsh also points to AI billing software that leads doctors to submit more claims and bill at higher levels29. Medicaid comes up as a cost driver too. Hospital groups already report more patients who are uninsured or can't pay, and many are expected to charge employers more to make up the lost revenue23. Marsh lists lower government health spending among the long-term forces keeping costs above inflation28.

Workers will pay a large share of the increase. Fifty-nine percent of employers plan cost-cutting changes such as higher deductibles22. About two-thirds of large employers expect to raise the share of premiums employees pay, so many paycheck deductions will rise by more than 8.2%29. Workers' total health costs rose 7.9% in 2026, according to Aon, and are expected to rise at a similar rate in 202722. The maximum out-of-pocket limit for 2027 rises to $12,000 for an individual and $24,000 for a family27.

How much Medicaid cuts add to premiums is disputed

Economists disagree about how much Medicaid cuts will raise private premiums. Research suggests hospitals absorb about 80% of the extra cost when uninsured patients increase. Some economists argue hospitals already charge private insurers close to the maximum, which leaves little room to pass on more12. Emory health policy professor Kenneth Thorpe estimates the federal cuts alone add 1% to 2% to premiums, or about $500 a year for an average family12.

Overall, the cost shift is real but limited. Most of next year's employer cost increase comes from drugs, hospital prices and consolidation, not Medicaid. The bigger risks from the Medicaid changes are for hospitals and patients. Hospitals will be left with more unpaid bills and fewer services, and patients will lose coverage because of paperwork. Once those losses push struggling hospitals to cut services or close, the higher costs and reduced access will affect people with every kind of coverage.
