Overview of the Ruling
A federal judge denied Minnesota’s motion to block a $243 million-plus Medicaid deferral on April 6, 2026. The court rejected the state’s request for a temporary restraining order and an expedited preliminary injunction. This ruling allows the Centers for Medicare and Medicaid Services (CMS) to move forward with one of the largest contested Medicaid fund deferrals in recent memory.
Background: The Medicaid Freeze That Started It All
How the Freeze Unfolded
Earlier this year, CMS froze approximately $259 million in Medicaid funds earmarked for Minnesota. Of that total, roughly $243 million was tied to services the federal agency classified as high-risk. Moreover, CMS warned Minnesota that it could withhold an additional $2 billion annually if program integrity concerns were not addressed.
The Scale of the Financial Risk
The sheer scale of the threatened withholding alarmed Minnesota health officials. Losing over $1 billion per year in Medicaid funding would strain the state’s healthcare infrastructure. Hospitals, community clinics, and vulnerable patient populations all depend heavily on this federal funding. Consequently, the state moved quickly to challenge the federal action in court.
Minnesota Files Suit Against Federal Agencies
The Legal Challenge Begins
On March 2, Minnesota filed a formal complaint against CMS, the Department of Health and Human Services (HHS), and their respective leaders. The state argued that the deferral was unlawful and sought emergency judicial relief. Specifically, Minnesota requested a temporary restraining order to halt the freeze while the broader legal dispute was resolved.
The State’s Core Legal Arguments
Minnesota’s legal team presented several arguments, including concerns about the deferral’s nature, its scope, and the federal government’s motivations for initiating it. Additionally, the state raised questions about whether proper federal procedures had been followed. The judge acknowledged these as “reasonable legal concerns,” though he did not find them sufficient to grant immediate relief.
CMS Approves Corrective Action Plan
A Key Development Mid-Dispute
Even as litigation continued, CMS approved Minnesota’s corrective action plan for addressing fraud, waste, and abuse. An assistant state attorney general informed the court that CMS Administrator Mehmet Oz, MD, indicated he would release the withheld funds once the state advanced a corrective plan.
State Confirmation of Plan Approval
Minnesota Deputy Human Services Commissioner John Connolly, PhD, confirmed the approval directly. He stated that CMS approved the plan “without changes or edits.” However, Dr. Connolly also flagged concern about the possibility of quarterly deferrals, noting that resolving the current deferral could take several quarters — leaving the state financially exposed in the interim.
Why the Judge Denied the Motion
The Court’s Three Key Reasons
The court outlined three primary reasons for denying Minnesota’s motion.
First, the federal agency’s proceedings were not considered “final” in the legal sense required to trigger judicial intervention. Second, the state’s legal theories were characterized as “novel,” meaning they lacked precedent to justify immediate relief. Third, the deferral appeared likely to comply with existing federal regulations, weakening the state’s argument for an injunction.
Furthermore, the court noted that the preliminary injunction request rested on certain assumptions rather than established facts in the record. Together, these factors led the judge to rule against Minnesota.
What the Court Left Open
The Door Is Not Fully Closed
Importantly, the judge stopped short of dismissing Minnesota’s case entirely. The court acknowledged that Minnesota had raised valid concerns. “All of this is not to say that Minnesota cannot prevail,” the opinion read. The judge added that the record might eventually support the state’s position, but that day had not yet arrived.
This language gives Minnesota a legal foothold to pursue the case further. As the record develops and more evidence comes to light, the state could return with stronger grounds for relief.
State Officials Respond
Disappointment and Next Steps
A spokesperson for the Minnesota attorney general’s office called the ruling disappointing. The office confirmed it is reviewing the decision in coordination with the Department of Human Services to determine its next course of action.
Dr. Connolly echoed this frustration. He warned that deferring $259 million “will have catastrophic impacts across our state’s healthcare infrastructure.” His concern centers not just on the current freeze but also on the precedent it sets for future federal action.
What This Means for Minnesota’s Healthcare System
A Warning for States Nationwide
This ruling carries implications well beyond Minnesota. States that receive significant Medicaid funding now face a sharper awareness of how quickly federal agencies can defer funds — and how difficult it can be to obtain emergency judicial relief. As federal oversight of Medicaid fraud, waste, and abuse intensifies, more states could find themselves in similar legal battles.
Ongoing Uncertainty
For Minnesota, uncertainty remains. CMS has threatened additional quarterly deferrals, and the state’s healthcare providers must plan for continued instability. Proactive corrective action and sustained legal strategy will both be essential as this dispute moves forward.
