BOSTON – The former owner of several physical therapy clinics in Greater Boston has been convicted by a federal jury of health care fraud charges.

Chang Goo Yoon, 61, a South Korean national residing in Queens, N.Y., was convicted yesterday following a seven-day jury trial on two counts of health care fraud. U.S. District Court Judge Indira Talwani scheduled sentencing for May 8, 2024. Yoon was arrested and charged by criminal complaint in February 2021 and subsequently indicted by a federal grand jury in May 2021. 

“This was about stealing and greed, pure and simple. Mr. Yoon exploited our healthcare system, and billed for fictitious treatments on dates that he was traveling abroad or holed up in a casino,” said Acting United States Attorney Joshua S. Levy. “This conduct was as brazen as it was illegal. Health care fraud is not a victimless crime. We all pay higher costs because of these types of fraudulent scams. Our office will continue to relentlessly pursue fraudsters and hold them accountable.”

“Chang Goo Yoon orchestrated a brazen scheme, abusing his position of trust as a health care provider to collect hundreds of thousands of dollars in payments for work he did not do. We thank the jury for its swift and prudent verdict,” said Jodi Cohen, Special Agent in Charge of the Federal Bureau of Investigation, Boston Division. “This conviction sends an unambiguous message that anyone who cheats our health care system will not get away with it.”

“This is exactly why the Insurance Fraud Bureau of Massachusetts was created over thirty years ago to combat insurance fraud and specifically this type of insurance fraud that increase the cost of insurance premiums for consumers in the state of Massachusetts. This case was borne out of a collaborative effort by our investigative partners. The perseverance and hard work done by all involved in this case is a demonstration that insurance fraud will not be tolerated in Massachusetts,” said Anthony DiPaolo, Chief of Investigations of the Insurance Fraud Bureau of Massachusetts.

“Mr. Yoon repeatedly lied and billed for services he never provided.  Actions which were fueled by nothing more than his greed,” said Ketty Larco-Ward, Inspector in Charge of the U.S. Postal Inspection Service. “We are pleased with the jury’s guilty verdict in this matter and thank them for their service.  It is our hope that this case serves as a warning to others who may use the U.S. Mail to further their criminal activities.”

Yoon was the owner and operator of several physical therapy clinics in Allston, Waltham and Brookline between 2014 and 2018. Yoon billed patients for non-existent physical therapy appointments, including approximately $150,000 in claims billed on dates when Yoon was traveling in South Korea, Los Angeles and Toronto. Yoon also billed $50,000 in claims on dates when he was gambling at casinos including the Golden Nugget in Atlantic City, N.J., MGM Springfield in Massachusetts and Twin River Casino in Lincoln, R.I. Additionally, Yoon submitted approximately $30,000 in physical therapy claims for himself after three automobile accidents. Most of those claims falsely listed one of Yoon’s employees as the servicing physical therapist. The remaining claims listed Yoon as both the patient and the servicing physical therapist.

The charge of health care fraud provides for a sentence of up to 10 years in prison, three years of supervised release and a fine of $250,000. Sentences are imposed by a federal district court judge based upon the U.S. Sentencing Guidelines and other statutory factors.

Acting U.S. Attorney Levy, FBI SAC Cohen, IFB Chief DiPaolo and USPIS INC Larco-Ward made the announcement. Assistant U.S. Attorneys Elysa Q. Wan and Patrick M. Callahan of the Criminal Division are prosecuting the case.
