UnitedHealth is target of DOJ probe for antitrust violations related to its Optum unit

In recent weeks, the Justice Department has been interviewing health care industry representatives in sectors where UnitedHealth competes to determine if the health care giant favored its Optum-owned doctor groups.

The U.S. Justice Department is conducting an antitrust investigation into UnitedHealth, owner of the biggest U.S. health insurer, and specifically into UnitedHealthcare’s relationship to its Optum business unit, according to a Wall Street Journal report.

In recent weeks, the inquiry is partly examining Optum’s acquisitions of doctor groups and how the ownership of physician and health-plan units affects competition, sources told the Journal. Investigators have asked whether UnitedHealthcare favored Optum-owned groups in its contracting practices, potentially squeezing rival physicians out of certain types of attractive payment arrangements.

Although both the Justice Department and the company declined to comment, executives have said Optum and UnitedHealthcare don’t favor one another and routinely work with competitors. The probe comes as the Biden administration’s antitrust enforcers have stepped up investigations of some of the largest U.S. companies and signaled that the health care industry is a priority in its antitrust efforts.

UnitedHealthcare has been under scrutiny on several legal fronts in recent years.

In addition to these legal battles, pharmacies nationwide reported delays in filling prescriptions last week following cyberattack against Change Healthcare.

UnitedHealthcare had $372 billion in revenue last year. Its insurance unit covers about 53 million people across a range of plans, including employer, Medicaid and Medicare coverage. After years of acquisitions, Optum includes about 90,000 physicians, as well as surgery centers, an array of health data and technology units, and one of the largest pharmacy benefit managers.
