Gustavo Kinrys, 49, a Natick psychiatrist, was arrested in connection with charges that he billed Medicare and private insurance companies for over $10 million in treatments he did not provide and then obstructed justice in an attempt to conceal his crimes. Kinrys was a licensed psychiatrist who owned and operated Advanced TMS Associates, located in Natick, Mass. Among other services, Kinrys offered transcranial magnetic stimulation (TMS) therapy and psychotherapy to patients suffering from depression. The indictment alleges that between January 2015 and December 2018, Kinrys engaged in a variety of fraudulent billing schemes in which he sought and received reimbursement for services he did not render. For example, Kinrys billed Medicare and private insurers over $10 million for thousands of TMS sessions he never provided, including over 8,000 sessions he claimed were provided to 75 patients who, in fact, never received a single session of the therapy. Kinrys allegedly billed Medicare and private insurers for hundreds of thousands of dollars’ worth of psychotherapy sessions he never provided, including over 1,000 face-to-face sessions he falsely claimed he provided while he or his patients were in fact out of the country. On hundreds of occasions, it is alleged that Kinrys billed Medicare and private insurers for having provided more than 24 hours’ worth of psychotherapy services in a single day, including one day in 2017 when he claimed he had provided hour-long psychotherapy sessions to 79 different patients.
