UnitedHealth Group Under Federal Investigation: Whistleblowers Encouraged to Come Forward

August 21st, 2025

UnitedHealth Group, the nation’s largest health insurer, has confirmed it is under federal investigation by the U.S. Department of Justice for its Medicare Advantage practices. This follows growing scrutiny from media outlets like The Wall Street Journal and STAT News, which raised serious concerns about the company’s billing and care management practices. The DOJ is reportedly investigating possible criminal fraud, and UnitedHealth has now acknowledged receiving both civil and criminal investigative requests.

This is just the latest in a series of crises for UnitedHealth, which has seen the abrupt resignation of top executives, mounting public backlash over care denials, and a massive drop in shareholder value—losing over $277 billion in market capitalization in the past year.
