Greenwich Psychologist Sentenced to 27 Months in Federal Prison for $2.6 Million Health Care Fraud Scheme

Vanessa Roberts Avery, United States Attorney for the District of Connecticut, today announced that MICHAEL LONSKI, 72, of Greenwich, was sentenced yesterday by U.S. District Judge Sarala V. Nagala in Hartford to 27 months of imprisonment, followed by three years of supervised release, for operating a $2.6 million health care fraud scheme.

According to court documents and statements made in court, Lonski was a licensed psychologist who, along with wife, Dr. Evelyn Llewellyn, maintained separate medical practices out of their home office in Old Greenwich.  Lonski and Llewellyn were authorized providers for the Connecticut Medicaid program (“Medicaid”), Medicare, and other health care benefit programs.  Lonski assumed responsibility for submitting claims for reimbursement for services allegedly provided by himself and Llewellyn, both at their home office and at various skilled nursing facilities within Connecticut.

For years, Lonski billed insurers for services that he knew were not rendered, including by billing for patients who were deceased, for dates of service when he was out of the country, for dates of service when Llewellyn was out of the country, and for dates of service when he was hospitalized.  From 2014 through 2019, Lonski submitted more than 80,000 claims for service, and he claimed to have provided services every single day, including weekends and holidays, except for one day in 2017.  On 60 of these dates, Lonski billed for more than 24 hours of service, and on 901 dates, Lonski billed for more than 12 hours of service.  These fraudulent claims resulted in a loss of over $2,651,294, including a loss of $1,157,292 to the Connecticut Medicaid program and a loss of $119,092 Medicare.

In 2002, Lonski settled a federal civil lawsuit alleging health care fraud, which was brought by the government in the Southern District of New York.  Lonski agreed to pay $4 million in restitution and was excluded from participating in all federal healthcare programs, including Medicare and Medicaid, for five years. 

Judge Nagala ordered Lonski to pay restitution $2,651,294.

On December 12, 2022, Lonski pleaded guilty to health care fraud.  Lonski is required to report to prison on March 25, 2024.

In May 2023, Llewellyn entered into a civil settlement agreement with the federal and state governments in which she agreed to pay $658,294 to settle allegations that she received payment for claims submitted by Lonski to the Medicare and Medicaid programs for psychology services allegedly provided by Llewellyn to Medicare and Medicaid beneficiaries that were, in fact, not provided.

This investigation was conducted by the U.S. Department of Health and Human Services, Office of the Inspector General (HHS-OIG), and the Federal Bureau of Investigation. The case was prosecuted by Assistant U.S. Attorneys Susan L. Wines, Richard M. Molot, and Christine Sciarrino
