Why It Matters
States across the country — including Oregon — that rely on Medicaid demonstration waivers to fund pilot health programs are facing significant new constraints from Washington. The changes could limit Oregon’s ability to expand services for low-income residents through flexible federal health funding, coming on the heels of nearly $900 billion in Medicaid cuts already signed into law.
What Happened
The Trump administration sent letters to state Medicaid directors announcing tighter financial oversight of so-called Section 1115 demonstration waivers — the federal mechanism that allows states to design and test alternative Medicaid coverage models. The changes are set to take effect January 1.
Under the new rules, the Centers for Medicare and Medicaid Services chief actuary must formally certify that any waiver will not increase federal Medicaid spending above baseline projections. States will also be required to submit more extensive spending analyses, documentation, and ongoing monitoring reports to satisfy federal reviewers.
The administration also announced it will no longer approve new Section 1115 waivers that include workforce development initiatives — a type of program several states had pursued to help Medicaid recipients gain employment. Additionally, the administration rescinded an expanded Biden-era framework that had allowed states to use waivers to address housing instability and other health-related social needs.
By the Numbers
- $900 billion in Medicaid cuts were enacted through the One Big Beautiful Bill Act, signed into law last summer, setting the backdrop for the new waiver restrictions.
- January 1 is the effective date for the new certification and documentation requirements.
- 4 states received waiver approvals in 2024 to cover traditional healing practices at tribal health facilities and urban Indian organizations — a category of waivers whose future is now uncertain under the tighter framework.
- Multiple states had used demonstration waivers to begin enrolling soon-to-be-released incarcerated individuals in Medicaid, a program model that will now face heightened federal scrutiny.
Zoom Out
Section 1115 waivers have long been a tool for states to expand Medicaid coverage beyond standard federal rules, often used to test programs aimed at housing support, pre-release prisoner enrollment, and tribal health services. The Biden administration had broadened the framework considerably, and the current administration is now rolling back much of that expansion.
For Oregon, which has pursued some of the more ambitious Medicaid demonstration programs in the country, the shift carries real consequences. The state has used waiver flexibility to fund a wide range of social services tied to health outcomes. Oregon’s Medicaid program has also been under financial strain, making federal funding certainty even more critical to state budget planners.
The restrictions on housing-related waivers are particularly notable. Several Mountain West and Pacific Northwest states had leaned into the Biden-era framework to address homelessness and housing instability through Medicaid channels. That pathway is now closed to new applicants.
The move to end new workforce-initiative waivers also eliminates a program type that some states had used to attach employment requirements or job-training components to Medicaid eligibility. While the Trump administration has generally supported Medicaid work requirements through other mechanisms, workforce waivers under the demonstration program apparently did not meet the administration’s revised cost standards.
What’s Next
States with existing waivers will need to comply with the new certification and documentation requirements as renewal cycles come due. States currently seeking new demonstration waivers will have to meet the stricter cost-neutrality standards, and waiver applications that include workforce development components will be rejected outright.
Oregon health officials have not yet publicly detailed how the changes will affect pending or planned waiver applications. With the January 1 effective date approaching, state Medicaid agencies across the country are expected to reassess their program portfolios and adjust spending projections accordingly.
The administration’s broader Medicaid overhaul — combined with these waiver tightening measures — signals a sustained federal effort to reduce Medicaid’s footprint and cost, leaving states with less room to innovate outside the program’s traditional boundaries.
