DOJ Charges 15 People in $90 Million Minnesota Medicaid Fraud Scheme

On May 21, 2026, the Department of Justice announced criminal charges against 15 defendants across five separate fraud schemes that collectively billed Minnesota's Medicaid programs for more than $90 million [1]. The announcement came on the same day that Aimee Bock, the convicted ringleader of the $250 million Feeding Our Future scandal, was sentenced to 500 months—roughly 41.5 years—in federal prison [2]. Together, the two events underscored a single, uncomfortable reality: Minnesota has become ground zero for health care fraud in the United States.

Acting Attorney General Todd Blanche traveled to Minneapolis to make the announcement personally. "Today, we are holding scammers accountable who ripped off the American taxpayer," Blanche said [1]. He was joined by CMS Administrator Dr. Mehmet Oz and Health Secretary Robert F. Kennedy Jr., who described the schemes as "organized theft that exploited the most vulnerable children in America" [3].

The Five Schemes

The 15 defendants are accused of defrauding seven state-managed Medicaid programs through five distinct operations, each targeting a different category of services [1].

Autism Services: $46.6 Million

The largest single scheme—and what the DOJ calls the biggest autism fraud case ever charged—centers on Shamso Ahmed Hassan, 55, and Hanaan Mursal Yusuf, 25, who allegedly operated Smart Therapy Center and Star Autism Center [1]. Prosecutors allege the pair paid kickbacks of up to $1,500 per month per child to families who allowed their children's names to be used for billing, diagnosed children with autism regardless of clinical need, and billed for therapeutic services that were never delivered [4]. Smart Therapy alone billed for more than 3,000 hours of caregiver services for a single family that received no training [5]. The two centers collectively billed $46.6 million and were paid $21.1 million between 2020 and 2024 from the Early Intensive Developmental and Behavioral Intervention (EIDBI) program [1].

To put the program's growth in context: EIDBI claims rose from $600,000 in 2018 to $400 million in 2025 [1].

Individualized Home Supports: $22.7 Million

Charles Wayne Healey, 61, and Katherin Suzan Larsen-Guthmiller, 66, are charged in connection with an alleged $22.7 million scheme involving Individualized Home Supports services [1]. Prosecutors allege the pair acquired more than 20 residences, concealed their ownership interests, billed for services that were misrepresented, and spent the proceeds on luxury items [1]. The Individualized Home Supports program's costs reached $700 million in 2025 [1].

Housing Stabilization Services: $15.7 Million

Eight defendants are charged with defrauding the Housing Stabilization Services (HSS) program of approximately $15.7 million [1]. Some of the defendants were residents of Pennsylvania who allegedly engaged in what prosecutors have termed "fraud tourism"—traveling to Minnesota specifically to register as providers and extract payments for services they never delivered [6]. The HSS program was shut down on October 31, 2025, in part because of rampant fraud [1].

Integrated Community Supports: $1.4 Million

One defendant is charged in a $1.4 million scheme involving the Integrated Community Supports (ICS) program. In one case, a provider billed for 24-hour monitoring of a disabled person but failed to deliver services—and continued submitting bills after the man died [5]. The ICS program cost taxpayers $183 million in 2025 [1].

Child Care Fraud: $5 Million

Two additional defendants are charged in child care fraud schemes totaling approximately $5 million [1]. One of them, Fahima Mahamud, is alleged to have ties to the Feeding Our Future operation [4].

The Defendants: Roles and Demographics

The 15 defendants include alleged business owners, providers, and operators who prosecutors say held undisclosed ownership stakes in service providers while simultaneously billing Medicaid [1]. Hassan and Yusuf are described as the organizers of the autism scheme. Healey and Larsen-Guthmiller allegedly managed the property-based fraud in the IHS program. The eight HSS defendants included out-of-state participants who prosecutors say came to Minnesota because of its comparatively easy provider enrollment process [6].

The charges span conspiracy to commit health care fraud, substantive health care fraud, conspiracy to defraud the United States, false statements related to health care matters, and money laundering [1].

The demographic dimension of Minnesota's fraud crisis is impossible to ignore. Across the broader wave of fraud prosecutions in the state—encompassing child nutrition, housing, and autism schemes—82 of 92 defendants are Somali Americans, according to the U.S. Attorney's Office for Minnesota [7]. This statistic has become politically charged, particularly after President Trump called Somali immigrants "garbage" and deployed federal immigration authorities to the state under Operation Metro Surge [7][8].

How Much Has Been Recovered?

The DOJ press release does not specify seizures or recoveries tied to the $90 million case specifically, which is still in its early stages. However, in the related Feeding Our Future case, Aimee Bock was ordered to repay nearly $243 million [2]. The broader Feeding Our Future probe has produced 66 convictions to date [9].

At the national level, Medicaid Fraud Control Units (MFCUs) recovered a record $2 billion in FY 2025, up from $1.4 billion in FY 2024, with criminal recoveries alone reaching $1.3 billion [10]. These figures represent a return of $4.64 for every dollar spent on enforcement [10].

The Medicaid fraud programs are jointly funded: the federal government typically pays 50% of Medicaid service costs in Minnesota, meaning that the $90 million in alleged fraud was split roughly evenly between federal and state funds [11]. The federal share is administered through CMS, while the state share flows through the Minnesota Department of Human Services (DHS).

Minnesota: Outlier or Canary?

The scale of fraud in Minnesota is exceptional by any measure. The U.S. Attorney's office in Minnesota has estimated that fraud may have consumed at least half of the $18 billion paid out through 14 high-risk Medicaid programs since 2018—a potential loss of $9 billion [12].

Spending across those 14 programs more than doubled in five years, rising from $2.06 billion in 2021 to $4.32 billion in 2025 [13].

But Minnesota is not unique in its vulnerability. A Paragon Health Institute analysis identified four Medicaid service categories—Applied Behavior Analysis for autism, Home and Community-Based Services, Non-Emergency Medical Transport, and Substance Use Disorder treatment—as nationally susceptible to fraud [14]. These are the same categories exploited in Minnesota. Personal care services attendants generated significantly more fraud convictions nationally than any other provider type in FY 2025 [10].

The federal Health Care Fraud Strike Force Program has charged more than 6,200 defendants who collectively billed over $45 billion since 2007 [1]. Minnesota's $90 million takedown, while large, fits within a national enforcement escalation: MFCUs reported 1,185 convictions in FY 2025, up from 1,151 in FY 2024 [10].

What makes Minnesota distinctive is less the methods used than the speed and scale at which they were deployed. Home and community-based services are inherently harder to monitor than institutional care because the services occur in private residences across the state rather than in facilities that can be inspected [13]. Minnesota's rapid expansion of these programs during and after the COVID-19 pandemic, combined with relaxed provider enrollment standards, created conditions that prosecutors say amounted to a "culture of fraud" [15].

What Went Wrong: Oversight Failures

A third-party vulnerability assessment conducted by the data analytics firm Optum, commissioned by Governor Tim Walz, reviewed nearly four years of Medicaid claims across the 14 high-risk programs from January 2022 through October 2025 [16]. The findings were stark: 90% of autism-related claims over that period were flagged as potentially problematic [16].

State-commissioned audits traced the problem to specific systemic failures: weak provider screening that allowed businesses to enroll with minimal verification, fragmented monitoring across agencies, missing documentation for grants, and billing rules that lacked basic safeguards [16].

The Minnesota Department of Human Services bore primary responsibility for provider oversight. CMS, the federal agency that co-funds Medicaid, has broader regulatory authority but historically delegated provider enrollment and monitoring to states. A House Oversight Committee hearing concluded that Governor Walz and Attorney General Keith Ellison "lied about knowledge of fraud and silenced whistleblowers" [17]—a characterization that both officials have disputed.

When enhanced oversight was finally applied, the results were immediate: Medicaid spending across the 14 high-risk programs dropped 29%—a $165 million reduction—in a single quarter [16]. That spending had been climbing at roughly $500 million per year, suggesting that a substantial share of the growth was driven by fraudulent billing rather than increased patient need.

The Bias Question

The prosecution of Minnesota's fraud cases has raised difficult questions about whether enforcement has disproportionately targeted Somali and immigrant communities.

The core statistical fact is that 82 of 92 defendants across Minnesota's fraud prosecutions are Somali Americans [7]. Critics of the enforcement approach argue that pattern-matching audits—which flag providers based on billing volume, newness to the program, and geographic clustering—inevitably concentrate on immigrant-owned businesses that entered the provider market during the pandemic-era expansion [8].

Governor Walz has argued that the Trump administration's simultaneous deployment of immigration agents under Operation Metro Surge undermined fraud investigations by destroying community trust. "The people of Minnesota have been singled out and targeted for political retribution at an unparalleled scale," Walz testified before Congress [8]. Attorney General Ellison noted that resignations within the U.S. Attorney's Office in Minnesota left remaining staff "drowning in immigration-related petitions" rather than prosecuting fraud cases [8].

Defense advocates contend that the Somali community was specifically recruited into provider roles for programs with weak oversight—and that the structural conditions that enabled fraud were created by state policy, not by the communities now facing prosecution. The Feeding Our Future case itself illustrates this complexity: the convicted ringleader, Aimee Bock, is white, while the majority of co-defendants are Somali American [7].

On the other hand, prosecutors maintain that the cases are conduct-based, not profile-based. Assistant Attorney General Colin McDonald stated: "The fraud here in Minnesota is shocking. This is not the end of our work" [3]. Federal investigators have told CBS News that there is no evidence taxpayer dollars were funneled to terrorist organizations like al-Shabaab, contradicting rhetoric that has been used to frame the cases as national security threats [7].

The tension between aggressive fraud enforcement and equitable prosecution remains unresolved. No independent statistical analysis has been published that controls for provider demographics against billing patterns to determine whether audit triggers correlate with ethnicity after accounting for conduct variables.

Sentencing Exposure

The charges filed against the 15 defendants carry significant prison time. Health care fraud carries a maximum penalty of 10 years per count, or 20 years if the offense results in serious bodily injury [1]. Conspiracy to commit health care fraud carries comparable penalties. Money laundering charges carry a maximum of 20 years per count. Wire fraud, charged in related cases, carries up to 20 years [9].

The Feeding Our Future sentencing provides the clearest benchmark for likely outcomes. Bock received 500 months (41.5 years) after conviction at trial on all counts—less than the 50 years prosecutors sought but well above the roughly 10-year sentences that have been typical for cooperating defendants who pleaded guilty [2]. Across the 66 Feeding Our Future convictions, the majority of defendants accepted plea agreements [9].

For the 15 newly charged defendants, the practical range of outcomes will depend on their roles. Organizers like Hassan, who allegedly controlled the $46.6 million autism scheme, face the most severe exposure—potentially 20 years or more if convicted at trial on multiple counts. Mid-level participants and the HSS "fraud tourists" are more likely candidates for plea agreements with sentences in the range of 5 to 15 years, consistent with federal sentencing guidelines for losses in the tens of millions of dollars. The federal sentencing guidelines calculate offense levels partly based on loss amounts, meaning the $22.7 million and $46.6 million schemes carry substantially higher guideline ranges than the $1.4 million ICS case.

Reforms and Their Cost

Minnesota and CMS have taken several concrete steps since the fraud crisis became public. In January 2026, in coordination with CMS, Minnesota implemented a freeze on new provider enrollments across 13 Medicaid service categories identified as high risk, initially for six months [18]. Providers of these services must complete revalidation by May 31, 2026, or face disenrollment [18].

Governor Walz ordered a third-party audit of Medicaid billing at DHS in October 2025, followed by a pre-payment review process that requires claims to be verified before funds are disbursed [16]. The Minnesota DHS has referred 300 potential fraud cases to law enforcement since the beginning of 2025 and has stopped payments to 636 providers [4].

At the federal level, the DOJ announced funding for 15 new prosecutors and associated staff dedicated to Medicaid fraud nationwide [1]. CMS announced sweeping anti-healthcare fraud initiatives in early 2026, including enhanced data analytics and cross-state provider screening [19].

Minnesota Attorney General Ellison has advanced the MAP Act through the state legislature, which would expand state-level fraud prosecution authority [20].

The cost of these reforms—Optum's audit, 15 additional federal prosecutors, pre-payment review infrastructure, and the administrative burden of revalidating hundreds of providers—has not been publicly quantified. But it can be measured against the returns: the 29% quarterly spending reduction alone saved $165 million, and nationally, every dollar spent on MFCU enforcement returned $4.64 in FY 2025 [10][16].

What Comes Next

The $90 million takedown is explicitly not the final act. "This is not the end of our work," McDonald said [3]. The DOJ has signaled that additional indictments are forthcoming as investigators continue to examine the broader $9 billion in potentially fraudulent claims [12].

The 15 defendants are presumed innocent until proven guilty. Federal district court judges will determine sentences after considering the U.S. Sentencing Guidelines and other statutory factors [1]. The cases will be prosecuted by the U.S. Attorney's Office for the District of Minnesota and the DOJ's Health Care Fraud Strike Force.

Minnesota's fraud crisis has exposed a national vulnerability: community-based Medicaid services, expanded rapidly during the pandemic with minimal oversight infrastructure, became targets for organized theft. Whether the state's belated reforms—enrollment freezes, pre-payment reviews, enhanced audits—can prevent the next wave of fraud while preserving access to services for the people who genuinely need them remains the central question that no indictment can answer.
