DiRenzo Jr. Joseph P, Unlawful Distribution of Controlled Substances, Pennsylvania 2020

⏱ 4 min read

In a shocking case of medical professionals gone rogue, three defendants in Pennsylvania have been charged with operating a pill mill that distributed controlled substances to patients via a voicemail refill line. Dr. Joseph P. DiRenzo Jr., Dr. Marc A. Matozzo, and physician’s assistant Joseph D. Norris allegedly prescribed powerful drugs like oxycodone and amphetamine to patients without ever interacting with them, from January 2020 to March 2025. The scheme, which allowed patients to receive refills for up to a year without a licensed prescriber, was uncovered as part of the Department of Justice’s 2026 National Health Care Fraud Takedown.

The indictment alleges that the defendants knew certain pharmacies had refused to fill their prescriptions, but they simply submitted them to other pharmacies instead. This brazen disregard for medical ethics and the law has sparked outrage, with U.S. Attorney David Metcalf condemning the defendants for fueling the opioid crisis. The charges against the three medical professionals include conspiracy to unlawfully distribute controlled substances, as well as multiple counts of unlawful distribution and false statements related to health care matters.

The case highlights the darker side of the medical profession, where some doctors and health care workers prioritize profits over patients’ well-being. As the opioid crisis continues to grip the nation, law enforcement agencies are cracking down on pill mills and other illegal distribution schemes. The DOJ’s 2026 National Health Care Fraud Takedown is part of a broader effort to hold medical professionals accountable for their actions and protect the public from the devastating consequences of addiction.

The defendants face serious charges, with potential sentences that could put them behind bars for years. As the case moves forward, it will be important to watch how the justice system holds these medical professionals accountable for their alleged crimes. The outcome could have significant implications for the medical community and the fight against the opioid crisis.
