In a scathing decision released Tuesday, a federal judge in Northern California ruled that a unit of UnitedHealth Group, the giant health insurer, had created internal policies aimed at effectively discriminating against patients with mental health and substance abuse disorders to save money.
U.S. Chief Magistrate Judge Joseph C. Spero found that United Behavioral Health, the insurer’s unit that administers treatments for mental illness and addiction in private health plans, had violated its fiduciary duty under federal law.
