Dr. Mehmet Oz, the administrator of the Centers for Medicare & Medicaid Services (CMS), is set to appear Tuesday in Philadelphia alongside senior federal law enforcement officials to announce what the U.S. Department of Justice is describing as a significant health care fraud takedown and the launch of a new anti-fraud initiative.
The 11 a.m. press conference at the William J. Green Jr. Federal Building will bring together Assistant Attorney General Colin M. McDonald of the Justice Department’s National Fraud Enforcement Division, CMS Administrator Dr. Mehmet Oz, U.S. Attorney David Metcalf for the Eastern District of Pennsylvania, Pennsylvania Attorney General Dave Sunday, and Department of Health and Human Services Inspector General T. March Bell.
The announcement comes as the Trump administration continues to make combating health care fraud a central priority, with CMS and the Justice Department increasing scrutiny of fraudulent Medicare, Medicaid, and Affordable Care Act claims.
Oz is expected to outline CMS’s role in the investigation and discuss how the agency is working with federal prosecutors and investigators to identify fraudulent providers, protect taxpayer dollars, and safeguard the integrity of federal health care programs.
Tuesday’s announcement builds on a series of recent enforcement actions by the administration aimed at tightening oversight of federal health care spending. In recent weeks, CMS has highlighted efforts to identify improper Medicaid enrollments, crack down on fraudulent billing practices, and defer federal matching funds to states where officials identified high-risk or irregular claims.
The Philadelphia announcement signals that those efforts are expanding beyond policy changes into high-profile criminal enforcement actions.
The Justice Department described the case as a “significant health care fraud takedown” and said it will also unveil a new District Anti-Fraud Initiative for the Eastern District of Pennsylvania. While officials have not yet released details about the scope of the investigation or the individuals and organizations involved, the participation of senior leaders from the Justice Department, CMS, HHS Office of Inspector General, the U.S. Attorney’s Office, and the Pennsylvania Attorney General’s Office suggests the operation involved extensive coordination among federal and state agencies.
Oz’s appearance also marks one of his highest-profile public events since becoming CMS administrator. Since taking office, he has largely focused on implementing President Donald Trump’s health care agenda, emphasizing program integrity, reducing waste, fraud and abuse, and increasing accountability within Medicare and Medicaid.
The press conference is scheduled for 11 a.m. Eastern Time and will be held at the William J. Green Jr. Federal Building in Philadelphia. The Justice Department said the event will also be livestreamed on its website. www.justice.gov/live
Additional details regarding the fraud investigation, arrests, charges, and the new anti-fraud initiative are expected to be released during the announcement.
