Maryland Man Facing Federal Indictment for Role in COVID-19 Healthcare Fraud Scheme Totaling More Than $100M

Greenbelt, Maryland – A federal grand jury indicted a Maryland man, today, in connection with a COVID-19 healthcare fraud scam.

Marc Aaron Potash, 57, of Rockville, is charged with conspiracy to commit healthcare fraud and seven counts of healthcare fraud. The charges stem from Potash submitting false and fraudulent claims to Medicare, Medicaid, the Federal Employees Health Benefits Program (FEHBP), and other insurers for at-home, self-administered COVID-19 tests. Potash is also charged with five counts of conducting transactions in criminally derived proceeds. This prosecution is part of the Trump Administration’s Task Force to Eliminate Fraud.

Kelly O. Hayes, U.S Attorney for the District of Maryland, announced the indictment with Special Agent in Charge Darren B. Cox, FBI Washington Field Office; Inspector General T. March Bell, U.S. Department of Health and Human Services, Office of Inspector General (HHS-OIG); and Michael R. Esser, Deputy Inspector General Performing the Duties of the Inspector General, Office of Personnel Management, Office of the Inspector General (OPM-OIG). 

According to the indictment, between January 2022 and May 2026, Potash allegedly conspired with others to personally enrich himself and maximize the financial success of Tiero, LLC, a company located in Gaithersburg, Maryland. Through the conspiracy, Potash, Tiero’s founder and chief executive officer, and his co-conspirators schemed to obtain money through false and fraudulent representations to insurers. 

The indictment further alleges that as part of the healthcare fraud scheme, Potash and his co-conspirators sent false emails, letters, and paperwork to the Maryland Department of Health (MDH) to obtain a Clinical Laboratory Improvement Amendments (CLIA) certification for Tiero. As part of the conspiracy, Potash and his co-conspirators submitted documents that falsely portrayed Tiero’s medical providers performing on-site COVID-19 testing at the company’s purported lab.  The co-conspirators then used Tiero’s CLIA license to submit fraudulent claims to insurers that listed false dates of service, a fake place of service, and a phony rendering provider for COVID-19 tests that would have been administered or analyzed by a provider at Tiero.
