Medicaid changes in 2027 for adults under 65 come from Public Law 119-21, the 2025 budget law also called the One Big Beautiful Bill Act, and the three that start on January 1, 2027 land on the expansion group: adults ages 19 to 64 with income up to 138% of the federal poverty level, which is $22,025 a year for one person under the 2026 guidelines. A work or activity rule decides who gets and keeps coverage, renewals come twice as often, and the window for Medicaid to pay bills from before your application shrinks from 3 months to 1. Each change below is tied to a next coverage option if Medicaid ends.
The federal budget side of the law is covered in the BenefitsUSA explainer Medicaid cuts in 2026. This page is the dated version for the person who has Medicaid or is about to apply: what changes, on which day, who is exempt, and what to do next. State rules differ in detail, so check your state Medicaid agency's notice. For the separate guides, see Medicaid work requirements, Medicaid renewal and Medicaid retroactive eligibility.
Coverage Breakdown
Direct answer: Medicaid changes for adults under 65 in 2027
Yes. For adults 19 to 64 in the Medicaid expansion group, three changes arrive in 2027: an 80-hour-a-month work or activity rule (every expansion state by January 1, 2027, some earlier), renewals every 6 months for renewals scheduled on or after January 1, 2027, and retroactive coverage cut to 1 month for applications made on or after January 1, 2027.
Medicaid work rules in 2027: who must show 80 hours a month
Medicaid work rules in 2027 apply to adults ages 19 to 64 in the expansion group, which is income up to 138% of the federal poverty level ($22,025 a year for one person in 2026), and to adults covered through certain waivers, including Georgia's and Wisconsin's. To get and keep coverage, an adult must show 80 hours a month of work, school, job training or volunteering, or monthly income of at least 80 times the federal minimum wage, which is $580 in 2026. A state can require applicants to show 1 to 3 months of hours before they apply, so the rule can stand between you and coverage at the application, not only at renewal.
Nebraska has enforced the rule since May 1, 2026. Montana went live on July 1, 2026, with denials and disenrollment from October 2026, and Iowa applies the rule to people who apply on or after December 1, 2026. Every other expansion state must start no later than January 1, 2027, unless the state gets a good-faith exemption from CMS, which can run no later than December 31, 2028. Write it on your calendar as starting as early as January 2027, depending on your state. Exempt groups include parents or caretakers of a child 13 or younger, pregnant women, people who are medically frail, and adults enrolled in Medicare. States must check payroll and other records first, so many working adults will not upload anything.
Missing the rule does not cancel coverage in one month. The state must send a notice of noncompliance and give you 30 calendar days to show you met the rule or are exempt, and Medicaid continues during those days. If you show nothing, the state checks whether you qualify on any other basis, then sends written notice with fair hearing rights. Public Law 119-21 section 71119 also treats a person who would qualify but for failing the rule as Medicaid-eligible for premium tax credit purposes, so a work-rule denial blocks the Marketplace credit while a full-price plan stays open. Details are in Medicaid work requirements.
Medicaid renewals every 6 months starting January 1, 2027
Medicaid renewals every 6 months apply to expansion adults whose renewal is scheduled on or after January 1, 2027, under section 71107 of Public Law 119-21. The old rule was one renewal per 12 months for most adults. American Indians and Alaska Natives are exempt, children and pregnant people keep their own renewal rules, and whether Wisconsin's waiver adults are included is unresolved, so read your state notice rather than assuming either way. In its March 6, 2026 letter to state Medicaid directors (SMD #26-001), CMS lets states move people to the 6-month cycle either by rescheduling dates for people enrolled in late 2026 or at their next scheduled renewal, so your first 6-month renewal date is on your notice.
Twice as many renewals means twice as many chances to lose coverage on paperwork while still eligible. States must first try to renew you from wage, tax and other records without asking for anything. If they cannot, they send a prepopulated form with at least 30 days to answer. If coverage ends because you did not return the form, federal rules at 42 CFR 435.916 require the state to reconsider without a new application if you send the missing information within 90 days of the termination date. Confirm your mailing address, phone and email now, set a reminder every 5 months, and read Medicaid renewal for the full process.
Shorter Medicaid retroactive coverage for applications from January 1, 2027
Retroactive Medicaid coverage lets Medicaid pay bills from before the month you applied, if you would have qualified at the time. Under section 71112 of Public Law 119-21, the look-back drops for applications made on or after January 1, 2027: to the month before the application month for expansion adults, and to the second month before for most other groups, down from the 3 months federal law allowed before. Applying on March 15, 2027 as an expansion adult reaches back to February 1, 2027. The same application in 2026 reached back about three months, so a hospital stay in January that you apply for in March is no longer covered for an expansion adult.
The practical step is timing. An application made on or after January 1, 2027 gets the shorter window, so a person who needs the full look-back and would qualify can apply before then, and everyone else should apply as soon as a health need appears instead of after the bill arrives. Some states already shortened or removed retroactive coverage for adults through Section 1115 waivers, so your state's rule may differ from the federal default. The state-by-state list is in Medicaid retroactive eligibility by state. For gaps Medicaid no longer reaches, ask the hospital for its financial assistance application before paying anything.
Medicaid and Marketplace income lines by household size (2026 guidelines)
Income lines by household size show which side of the 138% FPL boundary a household sits on, which decides whether the Medicaid changes above apply or the Marketplace is the next option. The Medicaid column uses the 2026 poverty guidelines, the current year, in the 40 states and DC that expanded Medicaid. The Marketplace columns are for 2027 coverage, sold from November 1, 2026, which uses the 2026 guidelines; 2026 coverage used the 2025 guidelines, where 400% of poverty was $62,600 for one person.
Alternatives if you lose Medicaid in 2027: your next coverage option for each change
Adults under 65 who lose Medicaid in 2027 have different next steps depending on why coverage ended. Open enrollment for 2027 Marketplace plans runs November 1, 2026 to January 15, 2027, and HealthCare.gov lists December 15 as the last day to enroll for coverage that starts January 1; that date is under court challenge, so confirm it on HealthCare.gov before relying on it. Losing coverage is a qualifying event for a special enrollment period, usually 60 days, so check your exact dates on HealthCare.gov the day you get a termination notice.
- Income over 138% FPL at a 6-month renewal: a Marketplace plan with the premium tax credit. For 2027 coverage the credit applies at 100% to 400% of poverty, $15,960 to $63,840 for one person and $33,000 to $132,000 for a family of four. Every ACA-compliant plan covers essential health benefits and cannot turn you away for a preexisting condition. Apply at HealthCare.gov or your state exchange.
- Work-rule denial: the Marketplace credit is blocked while the state counts you as eligible but for the rule, yet a full-price plan is open, and meeting the rule or proving an exemption lets you reapply. Adults who are exempt, or whose income is above 138% FPL ($22,025 for one person, 2026), are not caught by this bar.
- Employer coverage: losing Medicaid opens a special enrollment period at a job that offers a plan, and employer coverage counts as affordable at 10.22% of household income for 2027 plan years.
- Another Medicaid category: before ending coverage the state must check other bases, such as disability, parent or caretaker status or pregnancy. Ask the caseworker for that review in writing.
- Care while you sort it out: community health centers charge on a sliding fee scale by income (findahealthcenter.hrsa.gov), and nonprofit hospitals must have a financial assistance policy. This is care, not insurance, but it limits cost during a gap.
Original Medicare and disability: the Medicare exemption for adults under 65
Original Medicare is not a fallback for most adults under 65, but it matters to one group. Adults who are enrolled in Medicare Part A or Part B, which some people under 65 get after 24 months of Social Security disability benefits or with end-stage renal disease or ALS, are exempt from the work rule, and that includes people with a Medicare Advantage plan. Everyone else under 65 needs a Marketplace, employer or Medicaid route. If you have Medicare and Medicaid together, you are a dual eligible, and your renewal and exemption status should be checked together. Medigap rules for people under 65 vary by state, so ask your State Health Insurance Assistance Program before relying on one.
How to protect your Medicaid coverage before January 1, 2027
Protecting Medicaid coverage before January 1, 2027 comes down to four checks you can finish this month. First, make sure your state agency has your current mailing address, phone and email, because every notice about the work rule and the 6-month renewal goes to the contact information on file. Second, find out whether you are exempt and ask that the exemption be recorded. Third, if you are not exempt, start keeping proof of 80 hours a month or income of at least $580 a month (2026 figure). Fourth, if you plan to apply and expect bills, apply before January 1, 2027, which keeps the 3-month federal look-back unless your state has a waiver.
Frequently Asked Questions
What Medicaid changes start in 2027 for adults under 65?
Three changes reach expansion adults ages 19 to 64 starting January 1, 2027: the work or activity rule of 80 hours a month (some states started earlier), renewals every 6 months for renewals scheduled on or after that date, and retroactive coverage cut to 1 month for applications made on or after that date. Federal Medicaid also became limited to certain immigration statuses on October 1, 2026.
Do the Medicaid work rules start in every state on January 1, 2027?
Every expansion state must start by January 1, 2027, unless CMS grants a good-faith exemption that can run no later than December 31, 2028. Nebraska started May 1, 2026, Montana July 1, 2026, and Iowa applies the rule to people who apply on or after December 1, 2026. Check your state agency, because dates and exemptions can change.
Who is exempt from the 2027 Medicaid work rule?
Exempt groups include parents or caretakers of a child 13 or younger, pregnant women, people who are medically frail, adults enrolled in Medicare, American Indians and Alaska Natives, and others listed in the statute. A state must treat an exempt person as meeting the rule for the month. Ask your caseworker to record the exemption in writing so it carries to renewal.
How often will I renew Medicaid in 2027?
Expansion adults renew every 6 months instead of every 12 for renewals scheduled on or after January 1, 2027. American Indians and Alaska Natives are exempt. Children, pregnant people and people covered through age or disability keep the 12-month rule. Your state notice shows your first 6-month renewal date, because CMS lets states choose how to transition.
How far back does Medicaid pay bills if I apply in 2027?
For applications made on or after January 1, 2027, Medicaid can pay eligible bills from the month before the application month for expansion adults, and from the second month before for most other groups. Before that date the federal look-back was 3 months. Some states already had shorter rules through waivers, so check your state.
Can I get ACA Marketplace help if I lose Medicaid because of the work rule?
You can buy a Marketplace plan at full price, but not with the premium tax credit. Public Law 119-21 section 71119 treats a person who would qualify for Medicaid but for failing the work rule as eligible for Medicaid for credit purposes. Exempt adults and adults above 138% FPL ($22,025 for one person, 2026) are not caught by that bar.
What is the income limit for Marketplace help for 2027 coverage?
For 2027 coverage, sold from November 1, 2026, the premium tax credit applies at 100% to 400% of the 2026 poverty guidelines: $15,960 to $63,840 for one person and $33,000 to $132,000 for a family of four. For 2026 coverage the range was $15,650 to $62,600 for one person. Immigration limits on the credit also start with 2027 coverage.
Is Medicaid ending for expansion adults in 2027?
No. Medicaid expansion stays in 40 states and DC, and adults up to 138% FPL ($22,025 for one person in 2026) can still qualify. What changes in 2027 is how coverage is obtained and kept: proof of work or an exemption, renewals every 6 months and a shorter look-back for past bills. Many exempt or working adults will stay covered.
