Millions of adults who got health coverage through Medicaid expansion — and who have paid little or nothing at the doctor’s office — can now be charged up to $35 for a service under the 2025 federal law. States are permitted, and in some cases required, to impose these cost-sharing charges on expansion enrollees whose income is above the poverty line. For a household that has relied on Medicaid precisely because it kept care affordable, a new copay on each visit is a change worth understanding before the bill arrives.
What the new cost-sharing allows
The law lets states charge expansion adults above the federal poverty level up to $35 per service, with a guardrail: total cost-sharing cannot exceed 5 percent of a family’s income. The nonpartisan health-policy organization KFF, which tracks Medicaid policy in detail, has documented how the provision applies to the expansion population — adults who gained coverage under the Affordable Care Act’s expansion — rather than to traditional Medicaid groups like children and pregnant women, who remain broadly protected from such charges.
The $35 figure is a ceiling per service, not a flat fee on everything. States have latitude in how they apply it, and certain services are shielded. As the Center on Budget and Policy Priorities’ health research notes, primary care, prevention, and some other categories are typically exempt from the new charges, so the cost lands most heavily on other kinds of visits and services.

Who is protected and who is exposed
The dividing line is the poverty level and the coverage category. Expansion adults earning below the federal poverty line generally cannot be charged the new copays; the charges target those above it. Traditional Medicaid populations — children, pregnant women, and people who qualify through disability or other pathways — are largely outside this provision. Emergency care, family planning, and preventive services are among the categories states generally cannot attach the charge to, which limits the damage for someone who mainly uses primary and preventive care.
The 5 percent cap is the household’s backstop. Across a year, Medicaid cost-sharing for a family cannot exceed 5 percent of its income, counting premiums and copays together. For a family earning modestly above the poverty line, that cap still allows meaningful charges — but it prevents cost-sharing from spiraling without limit, and once the cap is reached, additional charges are not owed.
Why the timing varies by state
This is not a single national switch flipped on one date. The law sets the framework, but states implement it through their own Medicaid programs, so the effective date, the exact services charged, and how the 5 percent cap is tracked differ from one state to another. Some states will move quickly; others will phase it in. That means the only reliable answer to “what will I owe” comes from your own state Medicaid agency, not from a national headline.
Enrollees can find their state program and its rules through the federal Medicaid help directory, which links to each state agency. Asking directly whether your visits now carry a copay, which services are exempt, and how your state applies the 5 percent income cap is the way to avoid a surprise at the counter.
What it means for a tight budget
For a household near the poverty line, even a $35 charge per service can discourage needed care — which is the concern policy analysts have raised about cost-sharing in this population. The practical defense is to know the exemptions: keep using primary and preventive care that generally stays free, ask whether a given service carries a charge before agreeing to it, and track your cost-sharing against the 5 percent cap so you can stop paying once you hit it. If a charge appears that you believe should be exempt, your state Medicaid agency is the place to challenge it, and providers are generally required to follow the state’s cost-sharing rules rather than invent their own.
How the charges could ripple into your care
Policy analysts who study cost-sharing warn that even modest copays can change behavior in ways that end up costing more. A $35 charge for a specialist visit or a test can lead someone on a tight budget to skip or delay care, and a condition caught late is both worse for the patient and more expensive to treat. That is the central tension in the new charges: they are meant to raise revenue and discourage unnecessary use, but they fall on a population that already forgoes care when money is short.
For an individual household, the defense is knowing exactly what is and is not chargeable in your state, and using the protected services freely. Preventive care and primary care generally stay exempt, so keeping up with checkups, screenings, and vaccinations does not trigger the copay and can head off the costlier problems that do. If you are charged for something you believe should be free, ask the provider to check the state’s cost-sharing rules, and take the question to your state Medicaid agency, which you can reach through the federal Medicaid help directory. Tracking your charges against the 5 percent income cap matters too, because once you hit it, additional cost-sharing for the year is not owed.
