The United States Department of Justice (DOJ) has indicted a Nigerian, Olatunbosun Osukoya, in connection with a sweeping healthcare fraud operation valued at over $14.6 billion in intended losses described as one of the largest in US history.
Osukoya, 67, who resides in Plano, Texas, was among 324 individuals charged in the 2025 National Health Care Fraud Takedown spanning 50 federal districts and 12 State Attorneys General’s Offices across the United States. The DOJ said the defendants include 96 doctors, nurse practitioners, pharmacists, and other licensed medical professionals.
In a statement released on Thursday, the DOJ disclosed that the alleged perpetrators “exploited patients and taxpayers” through various schemes involving fraudulent claims and medically unnecessary procedures.
“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 statement read.
Osukoya, owner of Ayo Biometrics, LLC, which operates as Cambridge Diagnostics, was indicted on charges of conspiracy to commit healthcare fraud. According to court documents, he is accused of submitting more than $25 million in fraudulent claims to Medicare, TRICARE, and other insurers, primarily for electroencephalogram (EEG) testing.
The DOJ said Osukoya actively sought out individuals with insurance plans for costly lab testing and paid kickbacks to medical professionals to funnel patients to his diagnostic center.
“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,” the DOJ stated.
To disguise the illicit nature of the transactions, the indictment alleges that Osukoya and his co-conspirators falsified diagnoses and misrepresented illegal payments as legitimate business expenses — labelling them as loans, medical directorships, and consultation fees.
“To conceal the scheme and to make it appear that the services were necessary… kickback payments were falsely labelled,” the DOJ added.
Authorities said Cambridge Diagnostics received over $5 million in payments for the claims, with Osukoya allegedly disbursing more than $450,000 in illegal kickbacks.
Osukoya’s indictment is part of a broader federal crackdown on healthcare fraud, which U.S. officials say continues to strain public resources and endanger patients.
Meanwhile, in a related development, another Nigerian, Newton Ofioritse Jemide, was sentenced to three years and five months in prison by Judge Deborah K. Chasanow of 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.
