CMS Denies Minnesota $112 Million in Medicaid Funds
Federal regulators cite billing documentation gaps in high-risk Medicaid claims from late 2025.
Updated on Nov. 11, 2026 in Healthcare
The Centers for Medicare & Medicaid Services denied more than $112 million in Minnesota Medicaid reimbursements for the quarter ending September 30, 2025. The disallowance follows a $259 million deferral issued by CMS in February, and Minnesota has sued CMS and HHS over the frozen funds.
Why it matters
The denial affects how much federal Medicaid money Minnesota can recover for high-risk services delivered to recipients. Because CMS has deferred $550 million in total and has not yet ruled on two additional freezes totaling $350 million, the financial exposure for the state's Medicaid program could grow.
CMS reviewed 330 of more than 6 million high-risk claims filed in the quarter, and the $112 million denial is about 1,000 times larger than the claims first flagged. CMS has not yet ruled on two additional freezes totaling $350 million, and Minnesota has 60 days to appeal.
The players
Centers for Medicare & Medicaid Services
The federal agency that administers Medicare and oversees state Medicaid programs, including the review and disallowance of reimbursement claims.
Minnesota Department of Human Services
The state agency that administers Minnesota's Medicaid program and conducted the preliminary review of the rejected claims.
John Connolly
A Minnesota public official who said he is concerned CMS could issue more deferrals against the state.
The details
CMS rejected the claims over administrative documentation gaps, including missing or incomplete signatures, sign-offs, dates and addresses in billing records. The deferred services were high-risk services delivered from July through September 2025, and a preliminary state review found the rejections stemmed from these documentation issues.
Timeline
July through September 2025: High-risk services delivered to Minnesota Medicaid recipients.
September 30, 2025: End of the quarter for the disputed reimbursements.
February 2026: CMS issued a $259 million deferral to Minnesota.
March 2026: Minnesota sued CMS and HHS over the frozen funds.
November 2026: MPR News reported the $112 million denial.
Legal Context
The denial follows the standard CMS sequence of deferral followed by disallowance, which lets federal regulators withhold reimbursement while documentation is reviewed. The state's lawsuit now tests whether that process can be challenged while those funds remain frozen.
Minnesota's Medicaid program may face reduced federal reimbursement while the claims dispute is resolved, which could affect state budget planning. Providers in the state may also need to review billing records for missing signatures, dates and addresses to avoid similar rejections.
The takeaway
Complete and accurate billing documentation is what determines whether Medicaid claims are paid, so providers and state agencies should audit records for missing signatures, dates and addresses before federal review. Minnesota's appeal and the outcome of the pending $350 million freezes will show how much of the disputed funding can be recovered.
What happens next
CMS has not yet ruled on two additional freezes totaling $350 million, and Minnesota has 60 days from the disallowance to file an appeal.
