UnitedHealth Group’s stock plummeted over 13% following reports that the Department of Justice (DOJ) is conducting a criminal investigation into the company’s Medicare billing practices. The probe, ongoing since mid-2024, focuses on whether UnitedHealth inflated patient diagnoses to secure higher Medicare payouts. While the DOJ has not commented publicly, UnitedHealth denies any wrongdoing, stating it has not been formally notified of a criminal investigation. The company continues to defend the integrity of its Medicare Advantage program. — new from qz.com
