A new Medicaid work requirement takes effect nationwide by January 1, 2027, and "nationwide" turns out not to mean all fifty states. The Centers for Medicare and Medicaid Services says the requirement reaches 43 states and the District of Columbia, leaving several states outside its reach entirely and excluding every U.S. territory by statute rather than by choice. What is unsettled is whether that count of 43 will grow as more states adopt the coverage category the rule attaches to; what is settled, according to CMS’s own fact sheet, is exactly which side of that line every state and territory falls on today.
Why 43 States, Not All 50, Fall Under the Mandate
The number attaches to a specific piece of Medicaid architecture, not to geography for its own sake. Section 1902(xx) of the Social Security Act, the provision the interim final rule implements, applies only to states and the District of Columbia that elected to cover the Affordable Care Act’s Medicaid expansion adult group under a state plan amendment, or that cover comparable adults through certain Section 1115 demonstration waivers, according to the Federal Register notice CMS published June 3, 2026. A state that never adopted that coverage category has nothing for the new work requirement to attach to.
CMS’s own fact sheet puts a number on that filter: 43 states and the District of Columbia currently cover the population the rule addresses, and those are the jurisdictions required to build a community engagement system and start enforcing it by the deadline. The states missing from that count are, for the most part, the same states that never adopted the Affordable Care Act’s Medicaid expansion for adults, a decision several state legislatures made more than a decade ago and have not revisited since. The work requirement does not touch a state’s traditional Medicaid population, children, seniors, people with disabilities, at all; it only reaches the expansion adult group, so a state without that group has no one for the rule to cover.
That distinction matters for the seven states that sit outside the 43, because their absence from this rule reflects a coverage decision many of them made more than a decade ago, not an exemption CMS carved out in 2026. If any of those seven states later adopts the expansion adult group, or extends comparable coverage through a Section 1115 demonstration, the community engagement requirement would follow that coverage automatically, since the statute is written around a coverage category rather than a fixed list of states. Nothing in the interim final rule caps the number of covered jurisdictions at 44, from here, that count can only grow, not shrink.

The Territories’ Exclusion Is Written Into the Statute, Not Into CMS’s Rule
Puerto Rico, Guam, the U.S. Virgin Islands, American Samoa, and the Northern Mariana Islands sit outside the work requirement entirely, and the reason is in the same statutory sentence that produced the 43-state list. Section 1902(xx) applies, by its own text, to states and the District of Columbia; the territories are not named in that phrase, so CMS had no discretion to extend the requirement to them even if it wanted to, according to the Federal Register notice publishing the rule.
That is a different kind of exclusion than the one separating the 43 covered states from the seven that are not. A state escapes the mandate by never adopting the coverage category the rule attaches to; a territory escapes it because Congress wrote the underlying statute to reach only the fifty states and the District of Columbia. Territorial Medicaid programs have long run on a separate financing track, capped federal funding rather than the open-ended matching formula the states use, and that structural divide runs through the broader Medicaid statute, not just through this one rule.
For Medicaid enrollees across the five territories, the practical effect is that nothing about their eligibility changes on January 1, 2027, regardless of what happens in the 43 states now building compliance systems around them. CMS’s fact sheet does not describe any planned extension of the requirement to territorial programs, and because the exclusion is written into the statute rather than into CMS’s own rule, extending it to the territories would take an act of Congress, not a future agency rulemaking.
The January 2027 Deadline Binds All 44 Jurisdictions the Same Way
Every one of the 43 states and the District of Columbia faces the identical deadline: community engagement verification systems must be operating no later than January 1, 2027, under the interim final rule CMS published June 1, 2026. That gives covered states roughly nineteen months from publication to build the eligibility-checking infrastructure, income and hours verification, exemption processing, appeals, that a work requirement of this scale requires, and CMS has not described a state-by-state extension process for jurisdictions that fall behind.
The rule’s own label, an interim final rule with a comment period, is the unsettled half of this record. CMS put the requirement into legal effect on the deadline it set without waiting for a standard notice-and-comment process to finish first, which means the community engagement mandate is already operative for the 43 states, even as the public comment period that follows could still produce revisions before enforcement fully matures.
None of that comment process reopens the geographic scope, which is fixed by statutory language Congress wrote, not by anything CMS proposed in the rule itself. What could still change is a state moving into the 43 by adopting Medicaid expansion for adults, or Congress amending the underlying statute to reach the territories or redefine which adults the requirement covers. Until either happens, the January 2027 deadline applies to a fixed, statute-defined set of 44 jurisdictions, and the five territories remain outside a requirement that, by its own text, was never written to reach them.
