Los Angeles — The Department of Justice today announced criminal charges against 18 defendants in nine federal districts across the United States for their alleged participation in various fraud schemes involving health care services that exploited the COVID-19 pandemic and allegedly resulted in over $490 million in COVID-19 related false billings to federal programs and theft from federally funded pandemic programs.

Two of the most significant criminal cases in this sweep were filed by federal prosecutors in the Central District of California.

In connection with the enforcement action, the department seized over $16 million in cash and other fraud proceeds. The Center for Program Integrity of the Centers for Medicare & Medicaid Services (CPI/CMS) separately announced today that it took adverse administrative actions in the last year against 28 medical providers for their alleged involvement in COVID-19 schemes.

"The Justice Department will not tolerate those who exploited the pandemic for personal gain and stole taxpayer dollars," said Attorney General Merrick B. Garland. "This unprecedented enforcement action against defendants across the country makes clear that the Department is using every available resource to combat and prevent COVID-19 related fraud and safeguard the integrity of taxpayer-funded programs."

Today's announcement builds on the successes of the April 2022 COVID-19 Enforcement Action and the May 2021 COVID-19 Enforcement Action and involves the prosecution of various COVID-19 health care fraud schemes.

In one of the most significant types of COVID-19 health care fraud schemes announced today, multiple defendants were charged with defrauding the Health Resources and Services Administration (HRSA) COVID-19 Uninsured Program. The Uninsured Program was designed to prevent the further spread of the pandemic by providing access to uninsured patients for testing and treatment. The Uninsured Program was also designed to provide financial support to health care providers fighting the COVID-19 pandemic by reimbursing them for services provided to uninsured individuals. The Uninsured Program ultimately ceased operating due to the exhaustion of funding.

In the Central District of California, a medical doctor was charged for allegedly orchestrating an approximately $230 million fraud on the Uninsured Program.

Dr. Anthony Hao Dinh of Newport Coast, was the second highest biller in the country to the Uninsured Program. As a result of the scheme targeting the Uninsured Program, Dr. Dinh and his companies were paid more than $153 million, and he used fraud proceeds for high-risk options trading, losing over $100 million from November 2020 through February 2022, according to court documents.

Dr. Dinh allegedly submitted fraudulent claims for treatment of patients who were insured, billed for services that were not rendered, and billed for services that were not medically necessary, according to a criminal complaint filed on April 10.

After being arrested on April 12 and subsequently released on a $7 million bond, Dr. Dinh is scheduled to be arraigned in United States District Court on May 22. If he were to be convicted of the three charges, Dr. Dinh would face a statutory maximum sentence of 50 years in federal prison.

"Dr. Dinh is alleged to have stolen from a taxpayer-funded program meant to provide COVID-related health care to uninsured patients," said United States Attorney Martin Estrada. "We will not tolerate stealing from the American people, and our prosecution of this large-scale scheme demonstrates our continued efforts to stop fraud of all sorts."

Dr. Dinh is also charged with two other individuals for allegedly submitting over 70 fraudulent loan applications under the Paycheck Protection Program (PPP) and Economic Injury Disaster Loan (EIDL) Program and fraudulently obtaining over $3 million in loan funds. The other defendants named in this scheme are Dr. Dinh's sister – Hang Trinh Dinh of Lake Forest, who is currently a fugitive being sought by federal authorities – and Matthew Hoang Ho of Melbourne, Florida, who also was arrested on April 12. Dr. Dinh is charged in the complaint with health care fraud and two counts of wire fraud. Hang Dinh and Matthew Ho are each charged with one count of wire fraud.

The case against Dr. Dinh and his codefendants is being investigated by the U.S. Department of Health and Human Services' Office of the Inspector General, the FBI, IRS Criminal Investigation, the Department of Homeland Security, Office of Inspector General, the Defense Criminal Investigative Service, the AMTRAK Office of Inspector General, and the California Department of Health Care Services.

Assistant United States Attorney Roger A. Hsieh of the Major Frauds Section, and Justice Department Trial Attorneys Justin M. Woodard and Helen H. Lee of the Fraud Section are prosecuting this case.

In another case filed the Central District of California – this one by attorneys with the Justice Department's Health Care Fraud Strike Force – a lab owner was charged for allegedly submitting over $358 million in false and fraudulent claims to Medicare, HRSA, and a private insurance company for laboratory testing. The indictment alleges that the defendant's lab performed COVID-19 screening testing for nursing homes and other facilities with vulnerable elderly populations, as well as primary and secondary schools. But to increase its reimbursements, the defendant allegedly fraudulently added claims for respiratory pathogen panel tests even though ordering providers and facility administrators did not want or need them.

Lourdes Navarro of Glendale, was charged in a superseding indictment with conspiracy to commit health care fraud and wire fraud, health care fraud, conspiracy to commit money laundering, and making false statements, in connection with the operation of Matias Clinical Laboratory, Inc. (Matias), also known as Health Care Providers Laboratory, a laboratory she operated, controlled, and managed with her husband Imran Shams. Navarro was previously charged in an indictment returned in April 2022. The superseding indictment adds allegations that Navarro conspired with Shams and carried out a scheme to submit false and fraudulent claims to Medicare, the HRSA's COVID-19 Uninsured Program, and an insurance company for respiratory pathogen panel (RPP) testing that was not ordered, medically unnecessary, procured through illegal kickbacks and bribes, and ineligible for reimbursement.

During the COVID-19 pandemic, Matias performed COVID-19 screening testing for a variety of clients, including nursing homes, rehabilitation facilities, assisted living facilities, and similar facilities with vulnerable elderly populations, as well as primary and secondary schools. It is alleged that, in order to increase its reimbursements, Matias fraudulently added claims for RPP tests even though medical providers and facility administrators did not order them, and such tests were not needed for the patient population Matias served. It is further alleged that Matias falsely represented to HRSA that patients had been diagnosed with COVID-19 in order to obtain payment on the RPP claims. The superseding indictment alleges additional loss to Medicare, HRSA, and the insurer of approximately $241 million in billed claims, and alleges that these payors reimbursed Matias an additional $39.9 million. The case is being prosecuted by Trial Attorneys Gary Winters and Ray Beckering of the National Rapid Response Strike Force.

Today's announcement also includes first-of-their-kind charges against suppliers of COVID-19 over-the-counter tests, which Medicare began to cover in April 2022 for beneficiaries who requested them. These kits were provided to the public to slow the spread of the deadly disease, but wrongdoers allegedly sought to exploit the program by repeatedly supplying patients or, in some instances, deceased patients, with dozens of COVID-19 tests that they did not want or need. In the Middle District of Florida, a doctor and a marketer were charged for allegedly unlawfully purchasing Medicare beneficiary identification numbers and shipping over-the-counter tests to beneficiaries throughout the country who did not request the tests, causing over $8.4 million in fraudulent claims to Medicare.

Charges were also brought under the Health Care Fraud Unit's Provider Relief Fund (PRF) Initiative. The PRF is part of the Coronavirus Aid, Relief, and Economic Security (CARES) Act, a federal law enacted in March 2020 that provided financial assistance to medical providers to deliver needed medical care to Americans suffering from COVID-19. In the Eastern District of Louisiana, the operator of a primary care clinic and purported spa was charged with allegedly submitting fraudulent loan agreements, attestations, and other documentation from which she received over $1.1 million in PRF and EIDL funds that were used to purchase real estate, luxury vehicles, a boat, a trailer, a time share, and luxury vacations, among other expenditures. In total, 12 defendants have been charged with crimes related to misappropriating funds intended for frontline medical providers, and seven have pleaded guilty.

The law enforcement action also includes charges against manufacturers and distributors of fake COVID-19 vaccination record cards, who intentionally sought to obstruct the Department of Health and Human Services (HHS) and Centers for Disease Control and Prevention (CDC) in their efforts to administer the nationwide vaccination program and provide Americans with accurate proof of vaccination. In the Eastern District of New York, three medical professionals who worked at a small midwife practice were charged for allegedly distributing nearly 2,700 forged COVID-19 vaccination record cards to individuals who were not vaccinated. Instead of administering the COVID-19 vaccine, the defendants allegedly destroyed vials of COVID-19 vaccines that were intended to be used to inoculate patients. Despite being a small midwife practice, it was one of the busiest vaccination sites in New York State, outpacing large, state-run vaccination sites. In the District of Utah, two individuals were charged for allegedly manufacturing and selling online approximately 120,000 counterfeit COVID-19 vaccination record cards across the country, especially in areas that were subject to more stringent COVID-19 vaccine restrictions.

Today's enforcement action was led and coordinated by the Fraud Section in the Justice Department's Criminal Division. The Health Care Fraud Unit's Strike Forces in Brooklyn, the Gulf Coast, Los Angeles, and Tampa; the National Rapid Response Strike Force; and the U.S. Attorneys' Offices for the Central District of California, Middle District of Florida, Eastern District of Louisiana, Middle District of Louisiana, Western District of Louisiana, Eastern District of New York, District of Puerto Rico, District of Utah, and Western District of Washington are prosecuting these cases, with assistance from the Health Care Fraud Unit's Data Analytics Team.

In addition to the FBI and HHS-OIG, the Small Business Administration Office of Inspector General, Defense Criminal Investigative Service, Internal Revenue Service Criminal Investigation, Treasury Inspector General for Tax Administration, Homeland Security Investigations, Department of Homeland Security Office of Inspector General; Department of Defense Office of Inspector General, AMTRAK Office of Inspector General, California Department of Health Care Services, and other federal and state law enforcement agencies participated in the law enforcement action.

The Health Care Fraud Strike Force is part of a joint initiative between the Department of Justice and HHS to prevent and deter health care fraud and enforce current anti-fraud laws around the country. In the past three years, the Health Care Fraud Strike Force has rooted out health care fraud related to the COVID-19 pandemic. To date, 53 defendants have been charged in nationwide COVID-19 Health Care Fraud Enforcement Actions for causing over $784 million in loss associated with the pandemic, and 20 defendants have been convicted.

On May 17, 2021, the Attorney General established the COVID-19 Fraud Enforcement Task Force to marshal the resources of the Department of Justice in partnership with agencies across government to enhance efforts to combat and prevent pandemic-related fraud. The Task Force bolsters efforts to investigate and prosecute the most culpable domestic and international criminal actors and assists agencies tasked with administering relief programs to prevent fraud by, among other methods, augmenting and incorporating existing coordination mechanisms, identifying resources and techniques to uncover fraudulent actors and their schemes, and sharing and harnessing information and insights gained from prior enforcement efforts.

An indictment, complaint, or information is merely an allegation. All defendants are presumed innocent until proven guilty beyond a reasonable doubt in a court of law.
