The state and UPMC say one of Highmark's new Medicare Advantage products runs afoul of the recent consent decree signed by the two Pittsburgh health giants, and both are contemplating legal action in order to have the plan nullified by state courts. The plan in question is a narrow-network "Community Blue" insurance plan, with monthly premiums starting at $0. UPMC's hospitals are not part of the plan's physicians network, nor are those of Excela Health in Westmoreland County, Butler Health System or Washington Health System.
