A health insurance carrier is entitled to names and information identifying its insureds who have sued a pharmaceutical manufacturer, a Philadelphia judge has ruled on an issue of first impression.

Health insurer UnitedHealth Group plans to assert subrogation claims against drugmaker GlaxoSmithKline by stepping into the shoes of its insureds who took GSK’s Paxil and Avandia drugs and suing GSK over the alleged injuries its insureds experienced by taking those drugs, the June 16 opinion said.
