Owner of Physical Therapy Clinics Sentenced to More Than Two Years in Prison for Health Care Fraud

For Immediate Release
U.S. Attorney's Office, District of Massachusetts
Defendant submitted over $1 million in claims for appointments that never took place

BOSTON – The former owner of several physical therapy clinics in Greater Boston was sentenced on May 23, 2024 for health care fraud charges.

Chang Goo Yoon, 62, a South Korean national residing in Queens, N.Y., was sentenced by U.S. District Court Judge Indira Talwani to 27 months in prison and three years of supervised release. Yoon was also ordered to pay restitution in an amount to be determined at a later date. In January 2024, Yoon was convicted following a seven-day jury trial on two counts of health care fraud. 

“Mr. Yoon took advantage of his patients and the trust-based health insurance system for years by billing for appointments that never happened. In addition, he pressured his employees to participate in his unethical and illegal activities,” said Acting United States Attorney Joshua S. Levy. “These are not victimless crimes.  Health care fraud affects everyone by driving up costs for individuals and employers who pay into the health insurance system with their hard earned money. This sentence should send a strong message to others who seek to defraud the system that they will be identified, prosecuted and held accountable.”

“Today, we see yet another local physician going to prison for providing physical therapy services without a license and fraudulently billing for bogus appointments,” said Jodi Cohen, Special Agent in Charge of the Federal Bureau of Investigation, Boston Division. “This long-running scheme appears fueled by sheer greed, and the FBI and our partners are committed to bringing medical professionals like Chang Goo Yoon, who choose to betray their oath and get involved in fraud, to justice.” 

“This sentence shows that health care fraud is not tolerated in the Commonwealth of Massachusetts. The Insurance Fraud Bureau of Massachusetts places a high priority on fighting this type of insurance fraud, which affects the citizens of this state. We appreciate the collaboration of our investigative partners in combatting fraud in our healthcare system,” said Anthony DiPaolo, Executive Director of the Insurance Fraud Bureau of Massachusetts.

“Physical therapy patients deserve to receive treatment from a provider that will be honest with them and their health insurance provider” said Ketty Larco-Ward, Inspector in Charge of the U.S. Postal Inspection Service, Boston Division. “Dr. Chang Yoon lied about providing clinical services on dates he never saw patients and then had insurance payments fraudulently sent directly to him via U.S. Mail. Thanks to postal inspectors and our law enforcement partners, Dr. Yoon was sentenced today for his actions. The U.S. Postal Inspection Service is committed to protecting the integrity of the mail stream and all customers who use it.”

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.  

In total, the Court found that the defendant submitted more than $1 million in false insurance claims and reaped more than $300,000 in fraudulent proceeds.

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