Illinois Man Charged With Scheme To Impersonate Doctors And Make False Statements To Obtain GLP-1 Medications

United States Attorney for the Southern District of New York, Jamie McDonald, Assistant Director in Charge of the New York Field Office of the Federal Bureau of Investigation (“FBI”), James C. Barnacle, Jr., and Special Agent in Charge of the New York Regional Office of the U.S. Department of Health and Human Services Office of Inspector General (“HHS-OIG”), Naomi D. Gruchacz, announced that RODNEY GREER, a/k/a “Christian Marchand,” appeared for arraignment today in connection with a four-count Indictment charging GREER with a scheme to impersonate doctors to obtain unauthorized prescription medications on behalf of individuals who paid him. GREER was arrested in Chicago on June 17, 2026. This case is assigned to U.S. District Judge Arun Subramanian. “As alleged in the indictment, Rodney Greer impersonated and stole the identities of physicians and made false statements to pharmacies to obtain unauthorized prescription medications,” said U.S. Attorney Jamie McDonald. “This alleged conduct put scores of individuals in danger by allowing them to access prescription medication without the evaluation or approval of a licensed physician. The defendant now faces serious criminal charges for his alleged crimes.” “The misuse of a physician's personally identifiable information to fraudulently obtain GLP-1 medications is a serious crime,” said FBI Assistant Director in Charge James C. Barnacle, Jr. “Rodney Greer's alleged scheme not only compromises sensitive data, but also abuses systems designed to support legitimate patient care. The FBI does not tolerate fraud in any form, and we will continue to investigate those who exploit the healthcare system and the providers.” “The defendant in this case allegedly orchestrated an extensive scheme that generated hundreds of thousands of dollars in prescription claims paid by federal health care programs—claims that should never have been authorized,” said HHS-OIG Special Agent in Charge Naomi D. Gruchacz. “HHS‑OIG remains committed to working with our law enforcement partners to dismantle schemes that exploit federal health care programs and to hold accountable those who perpetrate such fraud.” As alleged in the Indictment:(1) Beginning in or about March 2023, GREER engaged in a scheme to impersonate physicians and make false statements to pharmacies and other third-party pharmacy benefit managers located throughout the United States in order to fraudulently obtain unauthorized prescription medications for customers in exchange for payments. GREER acquired personal identifying information (“PII”) for individual physicians, including their names and their national provider identification number (“NPI”). GREER maintained handwritten lists containing physicians’ PII for approximately 60 physicians located in approximately 19 states. Between on or about January 4, 2023, through on or about March 9, 2026, GREER called approximately 261 Pharmacies on approximately 3,329 occasions. Throughout that period, GREER used physicians’ PII and license information to impersonate them. GREER falsely claimed to be a health care provider; falsely identified himself as a physician; and provided other false information to receive GLP-1 and other prescription medications. By fraudulently inducing the provision of unauthorized medications to individuals who had not obtained prior authorization or approval for these prescription medications, GREER facilitated the unauthorized redemption of hundreds of thousands of dollars in healthcare plan benefits to the individuals who paid GREER for his services. * * * GREER, 51, is charged with one count of wire fraud, which carries a maximum sentence of 20 years in prison; one count of health care fraud, which carries a maximum sentence of 10 years in prison; and two counts of aggravated identity theft, each of which carries a mandatory term of two years in prison. The maximum potential sentences are prescribed by Congress and provided here for informational purposes only, as any sentencing of the defendant will be determined by a judge. Mr. McDonald praised the outstanding work of the FBI and HHS-OIG. The case is being prosecuted by the Office’s Complex Frauds and Cybercrime Unit. Assistant U.S. Attorneys Brandon C. Thompson and Georgia V. Kostopoulos are in charge of the prosecution. The charges contained in the Indictment are merely accusations, and the defendant is presumed innocent unless and until proven guilty. ^ As the introductory phrase signifies, the entirety of the text of the Indictment, and the description of the Indictment set forth herein, constitute only allegations, and every fact described therein should be treated as an allegation.
