Full story

UnitedHealth Group, the nation’s largest provider of Medicare Advantage plans, faces a Department of Justice (DOJ) criminal investigation for possible Medicare fraud, according to a report from The Wall Street Journal published Wednesday, May 14. The report says the exact allegations against the company are unclear, but that the inquiry has been underway since at least last summer.

The case is reportedly being handled by the health care fraud unit of the Department of Justice. The Journal did not indicate the likelihood of criminal charges being filed or a timeline for concluding the investigation.

What did UnitedHealth say?

In a statement released Wednesday, UnitedHealth said the DOJ has not notified the company of any investigation. The company also denounced the Journal’s reporting on the matter.

“The WSJ’s reporting is deeply irresponsible, as even it admits that the ‘exact nature of the potential criminal allegations is unclear,’” the statement said. “We stand by the integrity of our Medicare Advantage program.”

Not UnitedHealthcare’s only issue

The reported criminal investigation adds to a list of government inquiries into the company, including an investigation over potential antitrust violations. It also faces a civil investigation of its Medicare billing practices, which began in February.

Also in February, Sen. Chuck Grassley, R-Iowa, launched an inquiry into United’s Medicare billing practices.

Word of this investigation comes just days after UnitedHealth Group’s CEO resigned for personal reasons. The company also suspended its 2025 financial outlook, citing higher-than-expected medical costs.

UnitedHealth’s stock has declined by almost 50% over the past month, and shares plummeted to a four-year low after the Journal’s report was published Wednesday.

The company has dealt with a series of crises over the past year. Hackers disabled a unit that processes payments for health care providers. Additionally, the CEO of its health insurance subsidiary, UnitedHealthcare, was shot to death in what authorities have described as an assassination.

Not just United

UnitedHealth isn’t the only major insurer facing investigations. Earlier this month, the DOJ filed a complaint under the False Claims Act against three of the nation’s largest health insurance companies.

Those companies include Aetna Inc. and its affiliates, Elevance Health Inc., Humana Inc., eHealth, Inc. and an affiliate, GoHealth, Inc., as well as SelectQuote Inc.

The United States alleges that from 2016 through at least 2021 the insurers paid hundreds of millions of dollars in illegal kickbacks to the insurance brokers in exchange for enrollments into those insurers’ Medicare Advantage plans.

Why this story matters

The Department of Justice may be pursuing a criminal investigation into UnitedHealth Group, according to The Wall Street Journal, raising questions about the integrity of Medicare Advantage billing practices and regulatory oversight within the U.S. health care system.

Public funds, private companies

Federal scrutiny of UnitedHealth Group over alleged Medicare fraud reveals shared concerns regarding potential private mismanagement of public health care funds.

Corporate accountability

The investigations and recent company crises illustrate the importance of corporate responsibility and transparency in handling government health programs.

Broader insurer scrutiny

Multiple large insurers, not just UnitedHealth, are being investigated by the Department of Justice for their Medicare Advantage business practices, indicating a wider pattern of concern.

Context corner

Medicare Advantage allows private insurers to administer public Medicare plans for seniors, receiving higher payments for patients with more complex diagnoses. Historically, this system has faced scrutiny over billing practices such as “upcoding,” where insurers potentially exaggerate diagnoses to increase reimbursement. Prior civil actions and investigations against UnitedHealth and other insurers have set a precedent for governmental monitoring of the industry.

Do the math

Nearly half of the 65 million Medicare enrollees are in Medicare Advantage plans. UnitedHealth insures more than 8.2 million people and manages about 30% of these plans. Its stock fell by as much as 59% from its all-time high, with market capitalization dropping from $600 billion to $300 billion within a month.

History lesson

Medicare fraud investigations in the U.S. dating back decades often revolve around billing irregularities and the tension between private insurer incentives and government oversight. Previous high-profile lawsuits against UnitedHealth for civil Medicare fraud claims found the government struggling to secure convictions, frequently due to the complexity of proving fraudulent intent and contractual ambiguity in coding practices.
