Medicaid expansion enrollees in states like Nebraska and Michigan are receiving notices this summer that could determine whether they keep their health coverage. Under the federal interim final rule known as CMS-2454-IFC, states must verify that certain adults complete 80 hours per month of work or other qualifying activities. Anyone who fails to respond to a verification notice within 30 calendar days risks losing Medicaid coverage, even if they actually meet the requirement or qualify for an exemption.
Why the 30-day response clock creates immediate risk
The federal rule sets up a verification-first system. When a state cannot confirm through its own data that an enrollee meets the 80-hour monthly threshold, it must issue a noncompliance notice and give the person 30 calendar days to respond. That window is the same regardless of whether someone is working full time, caring for a family member, or enrolled in a training program. The burden falls on the individual to prove compliance or document an exemption once the notice arrives.
The practical danger is straightforward: a person who never opens the envelope, moves without updating an address, or simply cannot gather paperwork fast enough will be treated the same as someone who does not meet the requirement at all. States with weaker automated data-matching systems are likely to generate more of these notices because their databases cannot confirm employment or activity hours on their own. That means coverage losses in those states could be driven less by actual noncompliance and more by administrative friction.
The interim final rule from the federal health department describes this as a national framework for “community engagement” requirements. In practice, it relies heavily on state capacity to identify who should be subject to the rule, who should be exempt, and who can be verified automatically. The federal guidance emphasizes data matching and outreach, but it ultimately leaves the mechanics of notice design, call center staffing, and document processing to state agencies.
Nebraska and Michigan show how state rollouts differ
Nebraska’s Department of Health and Human Services is already mailing outreach notices to Medicaid expansion members. The state warns on its work requirements page that if DHHS requests additional information, it must be submitted within 30 days of the notice or the person may be denied coverage or lose it entirely. Nebraska has posted English and Spanish versions of its outreach notice, giving enrollees a head start on understanding what the state will ask.
Michigan’s approach follows a similar pattern. The state’s Healthy Michigan Plan guidance tells beneficiaries to watch for notices and respond by the printed due date. Michigan’s health department has said it will send a notice whenever it lacks the information needed to verify compliance or confirm an exemption. Neither state has published projections of how many people will receive these notices or how many are expected to qualify for exemptions.
At the federal level, health officials have framed CMS-2454-IFC as part of a broader strategy. In announcing a nationwide implementation framework, the agency described a phased rollout that gives states time to build or upgrade eligibility systems. The federal announcement highlights technical assistance for states, but it does not guarantee uniform outcomes for beneficiaries, especially in places starting from weaker administrative baselines.
The federal government has set a national implementation deadline of no later than January 1, 2027, for applicable states. That timeline means the summer and fall of 2026 represent the first large-scale test of whether state systems can handle the volume of verification requests without sweeping eligible people off the rolls.
Gaps in the evidence and what to watch next
Several questions remain open. No federal or state source has published the total number of enrollees expected to receive notices during the June-through-August mailing period. The actual templates being sent to enrollees are referenced on state websites but not widely available for independent review. And no data exists yet on how many people will successfully respond within the 30-day window versus how many will lose coverage by default.
The absence of verification success-rate data is the biggest gap. Earlier state-level experiments with work requirements under waivers suggested that many coverage losses stemmed from missed paperwork rather than true ineligibility, but those experiences occurred under different legal authorities and program designs. The new federal rule introduces standardized timelines and federal oversight, yet it still depends on how clearly notices are written, how reliably they reach people, and whether beneficiaries can access help completing forms.
Advocates and researchers will be watching several indicators as Nebraska, Michigan, and other states move deeper into implementation. One is the share of enrollees who are automatically verified through state data, never receiving a notice at all. Another is the proportion of people who respond within 30 days and are found to be meeting the requirement or exempt. A third is the number who lose coverage for nonresponse and later re-enroll, suggesting that procedural barriers, not substantive ineligibility, drove the initial loss.
State choices in the coming months could shape these outcomes. Decisions about whether to send reminders by text or email, how long call centers stay open, whether community organizations are funded to provide application assistance, and how quickly appeals are processed will all influence whether the 30-day clock functions as a fair safeguard or a trapdoor. Until detailed data are released, the central question remains unresolved: will CMS-2454-IFC primarily screen out people who do not meet the work requirement, or will it instead expose large numbers of eligible enrollees to avoidable gaps in coverage?
