The region's biggest healthcare players on Monday formally staked out positions in a court dispute over the confidentiality of the new affiliation agreement between West Penn Allegheny Health System and Highmark. Their briefs in U.S. District Court came in response to a Pittsburgh Post-Gazette motion to have the affiliation agreement made available to the public. It is currently filed in court but sealed from the eyes of all but a handful of attorneys and experts involved in a two-year-old lawsuit in which West Penn accuses UPMC of pursuing a local healthcare monopoly.
