BREAKING: US DOJ Indicts Nigerian for Masterminding $25M Medicare Fraud

The United States Department of Justice (DOJ) has indicted a Nigerian national, Olatunbosun Osukoya, in what authorities are calling one of the largest healthcare fraud crackdowns in U.S. history, involving an eye-popping $14.6 billion in intended losses.

Osukoya, 67, a resident of Plano, Texas, was among 324 individuals charged as part of the DOJ’s 2025 National Health Care Fraud Takedown, a massive federal operation spanning 50 U.S. federal districts and 12 State Attorneys General’s Offices.

According to federal authorities, the case represents a sprawling network of fraudulent healthcare activities across the country, with 96 of the defendants identified as doctors, nurses, pharmacists, and other licensed medical professionals.

Osukoya, who owns Ayo Biometrics, LLC, operating under the name Cambridge Diagnostics, is accused of orchestrating a fraudulent billing scheme that allegedly submitted more than $25 million in false claims to Medicare, TRICARE, and other federal insurance programs.

The claims were largely related to unnecessary electroencephalogram (EEG) testing.

The DOJ stated in its official release:

“As alleged in the indictment, Osukoya sought out individuals with insurance plans to undergo expensive EEG testing and recruited and paid kickbacks and bribes to physicians and others to refer patients to Cambridge Diagnostics.”

Investigators said Osukoya not only recruited patients through illicit channels but also disguised illegal payments by misrepresenting them as loans, consulting fees, and medical directorships, thereby attempting to legitimize what were, in fact, illegal kickbacks.

The DOJ further revealed that Cambridge Diagnostics received more than $5 million in federal reimbursements tied to the scheme, with Osukoya allegedly paying out over $450,000 in kickbacks to participating medical professionals.

Osukoya’s indictment is part of a larger national effort by U.S. federal authorities to curb systemic abuse of public healthcare programs such as Medicare, Medicaid, and TRICARE.

The DOJ emphasized that fraudulent activity of this scale endangers patient care and drains critical public resources.

“The Justice Department today announced the results of its 2025 National Health Care Fraud Takedown, which resulted in criminal charges against 324 defendants involving over $14.6 billion in intended loss,” the agency said in a statement.

The DOJ has vowed to continue aggressively pursuing fraudsters who exploit the healthcare system for personal gain, especially in a time when healthcare resources are already under significant pressure.

In a related but separate case, another Nigerian national, Newton Ofioritse Jemide, was sentenced to three years and five months in prison by Judge Deborah K. Chasanow in a U.S. District Court.

Jemide, who was extradited from France, was convicted of fraudulently obtaining $8 million in disaster relief grants intended for vulnerable American citizens during the COVID-19 pandemic.

Prosecutors said Jemide orchestrated a scheme to siphon off federal relief funds intended to support struggling individuals and businesses during the national emergency.

Both cases highlight growing concerns about transnational fraud networks involving foreign nationals who target the U.S. healthcare and financial relief systems. U.S. officials have signaled a zero-tolerance approach, warning that criminal actors  whether domestic or international  will be held accountable.

With Osukoya’s indictment and Jemide’s conviction, the spotlight intensifies on Nigeria-linked fraud cases, prompting questions about oversight, due diligence, and international cooperation in law enforcement.

If convicted, Osukoya faces decades in prison, significant financial penalties, and the possible forfeiture of assets obtained through fraudulent proceeds.

The DOJ has not yet announced his trial date, but officials say the investigation is ongoing and may lead to further charges or arrests.
