A former operations manager from New York has been sentenced to 14 months in federal prison for his role in a kickback scheme involving medically unnecessary brain scans. Timothy Doyle, 45, of Selden, New York, received the sentence from U.S. District Court Judge Nathaniel M. Gorton in Boston. In addition to prison time, Doyle was ordered to serve one year of supervised release and pay $27,225,434 in restitution as well as $1,102,725 in forfeiture.
Doyle pleaded guilty in January 2025 to one count of conspiracy to violate the anti-kickback statute. According to court documents, between June 2013 and September 2020, he conspired with others—including two managers at a mobile medical diagnostics company—to offer and pay kickbacks to doctors who ordered transcranial doppler (TCD) scans. TCD scans are used to measure blood flow in parts of the brain.
The investigation found that Doyle and his co-conspirators paid doctors kickbacks based on the number of TCD ultrasounds they ordered. The payments were disguised through sham rental and administrative service agreements that falsely appeared to compensate doctors for use of their office space or resources at fair market value rather than for referrals.
The fraudulent scheme led to approximately $70.6 million in bills submitted to Medicare, with Medicare ultimately paying about $27.2 million for these claims.
United States Attorney Leah B. Foley stated: "The details contained in the charging documents are allegations. The remaining defendants are presumed innocent unless and until proven guilty beyond a reasonable doubt in a court of law."
