Millions of Medicaid enrollees are about to receive a letter explaining new work requirements and twice-yearly eligibility checks that take effect in 2027, under a federal mailing deadline that most states are now weeks away from meeting.
The timing is fixed by statute. Notices must go out three months before the first month a state will look back at to verify compliance. For states starting the requirement on Jan. 1, 2027 with a one-month lookback at application, the first lookback month is December 2026, which puts the mailing at the turn of September for most states, according to a KFF analysis of the federal outreach rules. Idaho and Indiana, which reported plans to look back three months at applications, had a July deadline. State attorneys general have described the statutory deadline as Aug. 31, 2026, so enrollees in most states should be watching the mail now.
For households, the immediate consequence is a piece of mail that is easy to mistake for junk. The letter is not a renewal form and does not require an immediate response in most cases. It is the official notification that the terms of coverage are changing, and it establishes what a state must later prove it told enrollees.
The Letter Goes to Far More People Than It Applies To
One design choice in the federal rule shapes how confusing this month will be. Although the underlying law requires notices only for enrollees subject to the requirements, the interim final rule directs states to send notices to all Medicaid expansion adults and all enrollees in applicable waiver programs.
Federal officials explained the reason plainly: states do not have enough information to identify in advance everyone who should be excluded, and a person's circumstances can change between the mailing and the start date. The practical result is that many people who will never need to report a single hour will receive a letter describing hour requirements.
That includes a large share of parents. Many parents on Medicaid are covered through a mandatory parent eligibility pathway and are not subject to the new rules, but some parents of children older than 13 are covered through the expansion pathway and are. Most enrollees do not know which pathway covers them.
The rule requires each notice to explain who is subject to the requirement, how to comply, the consequences of noncompliance, and how many months the state will look back at renewal. Notices must arrive through at least two channels, including regular mail or an electronic format the person elected, plus at least one other such as phone, text, or an online account.
The Substance Behind the Mailing
The 2025 reconciliation law conditions Medicaid eligibility for adults ages 19 to 64 in the ACA expansion group, and certain waiver enrollees, on completing at least 80 hours per month of qualifying activity. Employment, self-employment, community service, a work or job training program, or at least half-time enrollment in school all count. A person can also satisfy the standard by earning at least $580 a month from paid work, a figure equal to 80 times the federal minimum wage.
The requirement applies in 44 states, a count that includes the District of Columbia, according to KFF's work requirements tracking, and reaches three non-expansion states through waiver programs: Georgia, Tennessee, and Wisconsin. Exemptions are mandatory for several groups, including people who are pregnant or postpartum, those who are medically frail, and parents or caretakers of dependent children under 14 or individuals with disabilities.
The second change arriving with it is the shift to eligibility redeterminations twice a year rather than annually for the affected population. That doubles the number of times a household has to complete paperwork correctly to stay covered.
Where the Paperwork Risk Concentrates
The population most exposed is not people who are out of work. It is people whose work is real but hard to document: seasonal labor, gig platforms, cash-paid caregiving, variable hours in food service and retail. Verification systems built around steady payroll records handle those patterns poorly.
Address instability compounds it. Enrollees who moved recently, are doubled up with family, or lack a stable mailing address are the least likely to receive a notice and the most likely to miss what follows. States are being encouraged in their own materials to remind enrollees to keep contact information current, which is the single most useful action available right now.
Several states have developed unofficial screening tools to help people determine whether the rules apply to them. New Jersey's screening tool asks about exemptions first and then about income and activity hours. West Virginia, Louisiana, and Wisconsin have launched similar tools. KFF noted that West Virginia's version does not ask about medical frailty, so it can miss an important exemption.
Reasonable Steps Before the Mail Arrives
Confirming that the state Medicaid agency has a current mailing address, phone number and email is the most valuable thing an enrollee can do this month. Most state agencies allow updates through an online account or the eligibility call center, though call centers generally operate during weekday business hours only, which limits access for people working during the day.
Reading the notice carefully when it comes to matters is more important than acting quickly on it. The letter should state whether the recipient appears subject to the requirement and how many months the state will review. Enrollees who believe they qualify for an exemption should not assume the state already knows, particularly where the basis is a health condition rather than an age or pregnancy status the agency can see in its records.
Nobody should drop coverage, stop a prescription or cancel an appointment because of a letter. Free enrollment assistance is available in every state through navigators and community health centers, and those organizations are being trained now on the new rules.
Several important questions remain unsettled. A coalition of states sued over the rule in late June, with 26 states represented by 24 attorneys general and the governors of Pennsylvania and Kentucky, arguing that federal officials had narrowed protections Congress had written into the statute. A federal judge declined in late July to pause the requirements while the case proceeds, dismissing that request without prejudice, so the litigation continues on the merits. States have also not finalized how generously they will apply exemption standards.
Key Questions Answered
When do the notices go out? Most states must send them around September, three months before December 2026, the first lookback month for states starting on Jan. 1, 2027. Idaho and Indiana had a July deadline.
Who receives one? All Medicaid expansion adults and all enrollees in applicable waiver programs, including many people who are exempt, because states cannot identify every exclusion in advance.
What does the requirement involve? At least 80 hours per month of work, self-employment, community service, job training, or half-time school, or at least $580 a month in earnings.
Does the letter require a response? In most cases, no. It is an informational notice, not a renewal form, though enrollees should read it to see what the state says applies to them.
Which groups are exempt? Mandatory exclusions include people who are pregnant or postpartum, those who are medically frail, and parents or caretakers of children under 14 or of people with disabilities.
What is changing about renewals? Affected enrollees move from annual eligibility redeterminations to checks twice a year.
What is the most useful thing to do now? Confirm the state Medicaid agency has a current address, phone number, and email, and watch the mail through the fall.
