United States of America v. Gary Cox

Miami, Florida, criminal defense lawyer represented the Defendant charged with conspiring to defraud Medicare and other federal health care benefit programs of more than $1 billion by operating a platform that generated false doctors’ orders used to support fraudulent claims for various medical items.

The Defendant was found guilty and was sentenced to 15 years in prison and ordered to pay more than $452 million in restitution.


Gary Cox, 79, of Maricopa County, was the CEO of Power Mobility Doctor Rx, LLC (DMERx). Cox and his co-conspirators targeted hundreds of thousands of Medicare beneficiaries who provided their personally identifiable information and agreed to accept medically unnecessary orthotic braces, pain creams and other items through misleading mailers, television advertisements and calls from offshore call centers. Cox and his co-conspirators owned, controlled and operated DMERx, an internet-based platform that generated false and fraudulent doctors’ orders for these items. As part of the scheme, Cox connected pharmacies, durable medical equipment (DME) suppliers and marketers with telemedicine companies that would accept illegal kickbacks and bribes in exchange for signed doctors’ orders transmitted using the DMERx platform. Cox and his co-conspirators received payments for coordinating these illegal kickback transactions and referring the completed doctors’ orders to the DME suppliers, pharmacies and telemarketers that paid kickbacks and bribes for the orders.

The fraudulent doctors’ orders generated by DMERx falsely represented that a doctor had examined and treated the Medicare beneficiaries when, in fact, purported telemedicine companies paid doctors to sign the orders without regard to medical necessity, based only on a brief telephone call with the beneficiary or no interaction with the beneficiary at all. The DME suppliers and pharmacies that paid illegal kickbacks in exchange for these doctors’ orders billed Medicare and other insurers more than $1 billion, and Medicare and the insurers paid more than $360 million based on these claims. According to evidence presented at trial, Cox and his co-conspirators concealed the scheme through sham contracts and by eliminating from doctors’ orders what one co-conspirator described as “dangerous words” that might cause Medicare to audit the scheme’s DME suppliers.

In June 2025, Cox was convicted of conspiracy to commit health care fraud and wire fraud, three counts of health care fraud, conspiracy to pay and receive health care kickbacks and conspiracy to defraud the United States and make false statements in connection with health care matters.

The FBI, HHS-OIG, VA-OIG and DCIS investigated the case.

Trial Attorneys Darren C. Halverson and Jennifer E. Burns of the Criminal Division’s Fraud Section prosecuted the case. Fraud Section Trial Attorney Shane Butland assisted in the prosecution. Trial Attorney Evan N. Schlom with the Fraud Section’s Special Matters Unit provided valuable assistance.
