Republican lawmakers in Jefferson City are moving to lock new work and community-participation rules into Missouri's Constitution for many adult Medicaid recipients, setting up a potentially fierce statewide vote in 2026.
The Missouri House voted this month to advance a proposed constitutional amendment that would write federal-style "work requirements" into MO HealthNet, the state's Medicaid program. For many adults in the expansion population, meeting those rules would become a condition of eligibility. Backers say the move is about protecting state policy even if federal rules shift later. Critics warn that stricter exemptions and added paperwork could knock vulnerable Missourians off the rolls. The resolution now heads to the state Senate and - if both chambers sign off - would land on the November 2026 ballot.
What the amendment would do
House Joint Resolution 154 would repeal the current Section 36(c) of Article IV and replace it with detailed language defining who is an "applicable individual," adopting the federal definition of "work requirements" and directing the Department of Social Services and the MO HealthNet Division to run those rules.
According to the Missouri House, the proposal would require documentary proof that people are meeting the requirements, explicitly banning self-attestation. Noncompliance could lead to disenrollment. The amendment also limits optional exemptions unless lawmakers choose to expand them, and it sets a deadline for the state to submit any needed Medicaid state plan amendments to the Centers for Medicare and Medicaid Services to get the new framework approved.
Where it stands in the legislature
The resolution cleared the House in February, with a third-reading vote of 99-48, and has been sent to the Senate for the next round of debate. Senators assigned it to the Families, Seniors and Health Committee, where members will take public testimony, work through implementation questions and consider any tweaks before it moves to the floor.
The full procedural history and roll calls are posted on the LegiScan record.
Cost and implementation
All of this is unfolding against an aggressive implementation timeline created by recent federal legislation that requires states to verify work or engagement for certain Medicaid expansion enrollees. House budget staff warn the constitutional change could come with a real price tag, especially if the governor opts for a stand-alone vote.
The House fiscal note flags both election and administrative costs, estimating that a governor-called special election could run around $9 million, and it points to broader fiscal uncertainties tied to how the requirements are ultimately administered. The Department of Social Services has already begun lining up IT changes and staffing to hit federal benchmarks, work described on the Missouri Department of Social Services site and in the Missouri House fiscal analysis.
Supporters and critics
Resolution sponsor Rep. Darin Chappell has framed the measure as a way to cement Missouri's expectations around Medicaid work rules so they are not at the mercy of changing administrations in Washington. "Someday that law may be changed, and I believe that this is good policy, and it needs to be on a permanent level within the state," he told reporters, according to KCUR.
Health advocates and policy analysts see it differently. They argue that layering on stricter state rules and heavier paperwork demands risks creating what they call "administrative churn" - people cycling on and off coverage, not because they are ineligible, but because they cannot navigate the documentation. National modeling aggregated by State Health & Value Strategies cites a Manatt Health analysis that projects substantial coverage impacts at the state level under similar federal proposals.
Local reporting has also noted that the governor's budget includes a multi-million dollar implementation request for the new rules, and one estimate has suggested that tens of thousands of Missourians could ultimately be at risk of losing coverage over time, according to Missouri Independent.
What comes next for voters
If the Senate approves HJR 154 and the House signs off on any changes, the resolution would go to Missouri voters at the next general election, currently set for November 2026, unless the governor calls a special election earlier.
The ballot question would ask Missourians whether to amend the state Constitution to allow these work or engagement requirements for MO HealthNet recipients. A simple majority would lock the policy into the Constitution. For those keeping a close eye on the measure's path, committee schedules, amendments and vote updates are available on its LegiScan page as it moves through the Senate.
