Oz vs. California: A Deep Dive into Healthcare Fraud Allegations

Recent accusations from Dr. Mehmet Oz, Administrator of the Centers for Medicare & Medicaid Services (CMS), have ignited a public dispute with California leaders over the state’s handling of healthcare fraud. Allegations of widespread abuse, particularly within the hospice and home health care sectors, have prompted investigations and a civil rights complaint, raising questions about the scale of the problem and the best approach to combatting it.

The Core of the Dispute

Dr. Oz has publicly claimed approximately $3.5 billion in fraud exists within the hospice and home health care industry in Los Angeles County alone. He asserted that the Trump administration would not tolerate the misuse of taxpayer dollars and suggested a significant portion of California’s home and community-based services spending could be fraudulent. These claims centered around allegations of organized crime involvement, specifically referencing the “Russian, Armenian mafia.”

However, CMS later clarified that the $3.5 billion figure represents overall Medicare billing related to these services and not necessarily fraudulent activity. A definitive determination of fraudulent amounts requires a thorough, evidence-based investigation, according to CMS spokesperson Chris Krepich.

California’s Response and Counterclaims

California officials have strongly refuted Dr. Oz’s accusations. Governor Gavin Newsom filed a civil rights complaint against Oz, arguing that the allegations were “baseless and racially charged.” California Attorney General Rob Bonta stated that the Trump Administration was attempting to “weaponize” the issue of fraud against Democratic states.

State officials maintain they are actively combating fraud, pointing to data indicating California outperforms many other states in recovering fraudulent funds. In fiscal year 2024, California recovered over 50% of all criminal recoveries made by the anti-fraud units nationwide, despite representing only about 17% of total Medicaid enrollment. The state ranked fourth in the U.S. In dollars recovered per Medicaid enrollee, trailing only the District of Columbia, Montana, and Delaware. KFF Health News

National Trends in Healthcare Fraud

Healthcare fraud is a nationwide issue, with approximately $3.4 billion in Medicare and Medicaid fraud recovered in fiscal year 2023. KFF Health News Whereas Dr. Oz focused on California, investigations and settlements have involved insurers and other domestic actors across the country.

The Trump administration, under Vice President J.D. Vance and Secretary of Health and Human Services Robert F. Kennedy, Jr., announced a crackdown on healthcare fraud in February 2026, including a temporary hold on $259.5 million in Medicaid funding to Minnesota due to similar allegations. CMS This action has similarly led to legal challenges from Minnesota.

Focus on Hospice Fraud

Hospice care, intended for patients with a six-month life expectancy, has grow a focal point in fraud investigations. The use of hospice services increased by over 8% from 2020 to 2024, driving up costs. KFF Health News

Both the Biden and Trump administrations have increased oversight of hospices in several states, including California, Arizona, Nevada, Texas, Ohio, and Georgia. A 2022 state audit in California revealed “numerous indicators” of large-scale fraud in Los Angeles County, highlighting nearly 500 hospices within a small geographic area. KFF Health News

California has taken action, revoking the licenses of over 280 hospices in the past two years and evaluating an additional 300. KFF Health News

The Broader Context

Experts like Georgetown University professor Andy Schneider emphasize that healthcare fraud has been a persistent issue for decades. KFF Health News The current dispute highlights the challenges of balancing federal oversight with state autonomy in addressing this complex problem. The allegations of mafia involvement, initially raised by Dr. Oz, have roots in a 2010 Justice Department investigation into an “Armenian-American organized crime enterprise,” but more recent investigations have not explicitly linked hospice fraud to foreign organized crime.

The conflict between the federal government and California continues, with both sides asserting their commitment to protecting taxpayer dollars and ensuring quality healthcare access.
