Not every parent on Medicaid answers to the same set of rules, and the new work requirement is exposing how many people don’t know which set applies to them. One group of parents has been shielded from Medicaid work rules for decades under a mandatory coverage category that predates the Affordable Care Act. Another group, covered because their state expanded Medicaid, is now squarely inside the new 80-hour-a-month requirement — and researchers say most of them can’t say which one they are.
The gap isn’t a paperwork oversight on any one family’s part. It’s built into how Medicaid eligibility categories work, and it’s showing up now because the work requirement singles out one category and leaves the other alone. It surfaces at the exact moment the government is asking millions of parents to prove something about themselves, using a system that was never designed to make that distinction obvious to the people living inside it.
Two Different Doors Into Medicaid Coverage
Medicaid has covered low-income parents and caretaker relatives through a mandatory eligibility pathway since long before the Affordable Care Act existed, based on income limits each state sets on its own. That pathway carries no federal work requirement today and isn’t touched by the new rule. A separate pathway — the ACA’s adult expansion group, created when a state chooses to expand Medicaid to adults up to 138% of the poverty line — is where the new requirement actually lives. The interim final rule defines an “applicable individual” subject to the requirement specifically as someone eligible under the expansion group described in section 1902(a)(10)(A)(i)(VIII) of the Social Security Act, or a comparable Medicaid expansion waiver, not the older mandatory parent category.
A parent’s Medicaid case can sit in either pathway depending on their income relative to their state’s specific cutoffs, which vary by state and by household size. Two neighbors with similar incomes and the same number of kids can land in different categories depending on exactly where their state draws that line.

Where the Confusion Starts on Paper
Research from Georgetown University’s Center for Children and Families found that many parents covered through the older mandatory pathway aren’t subject to the work requirement at all, while parents covered through the expansion pathway — including, in a number of states, parents of older children who no longer qualify for the more generous mandatory income limits — are. Its analysis of how parents are affected points out that most enrollment and renewal notices don’t spell out which pathway a household is actually in; they use general Medicaid language that reads the same regardless of category. State Medicaid agencies track the distinction internally through an eligibility or aid category code attached to every case, but that code rarely appears anywhere in the plain-language letters parents actually receive.
That means the same outreach mailer required under the rule can land in two different homes, one where the parent genuinely needs to start logging hours, and one where the requirement doesn’t apply at all, and both letters can look nearly identical to the person opening them.
Why Getting It Wrong Has Real Consequences
The stakes run in both directions. A parent in the exempt mandatory pathway who wrongly assumes the work requirement applies to them may spend hours gathering pay stubs or work-program paperwork they never needed. A parent in the expansion pathway who wrongly assumes they’re exempt, because a neighbor or relative in the mandatory pathway isn’t affected, risks missing a reporting deadline and losing coverage over a requirement they genuinely had to meet. KFF’s analysis of the outreach rules notes this is precisely why states are required to target their communications rather than send one generic notice to the entire Medicaid population — a broad, undifferentiated mailer risks confusing enrollees who were never going to be affected in the first place.
That kind of category confusion has a recent precedent. During the 2023–2024 unwinding of pandemic-era coverage protections, people were disenrolled in large numbers for procedural reasons that had nothing to do with whether they actually still qualified for coverage. Advocates worry the same pattern — people losing coverage over confusion about which rules apply to them, rather than because they failed to meet a rule that genuinely applied — could repeat itself here at a larger scale.
Finding Out Which Pathway You’re In
The most direct way to settle the question is to call the state Medicaid agency and ask specifically which eligibility category or “aid code” a case is assigned to, rather than relying on the wording of a mailed notice. Many state eligibility notices list an aid category code that maps to a specific pathway, even when the notice’s plain-language description doesn’t spell out the difference between mandatory and expansion coverage. A caseworker can confirm on the spot whether a parent’s case is coded under the expansion group or an older mandatory category, and CMS’s community engagement resource page lists where to find a state’s contact information.
Parents whose Medicaid eligibility changed in the past few years, whose child recently aged past a state’s caretaker-relative cutoff, or who applied more recently than the rest of their household are the most likely to have landed in the expansion pathway without realizing it. A single phone call rarely takes more than a few minutes, and it produces a definite answer, unlike guessing from the tone or design of a letter that was written to cover an entire state’s Medicaid population at once.
