It is a large individual not-for-profit health insurer in the United States, which operates several for-profit subsidiaries. Locality It is a health insurer in Pennsylvania, and through a purchase in 1996, an insurer in West Virginia and also later Delaware. As Highmark Blue Cross Blue Shield, it is primarily available in 29 counties of western Pennsylvania. As Highmark Blue Shield, it is available in 21 counties in Central Pennsylvania and the Lehigh Valley. It also has a presence in the border areas of eastern Ohio, and all of West Virginia through its subsidiary, Highmark Blue Cross Blue Shield West Virginia. Highmark acquired Blue Cross of Northeastern Pennsylvania, BCNEPA, in June 2015. Company history Highmark was created in 1977 and in the 1990s by the consolidation of two Pennsylvania licensees of the Blue Cross and Blue Shield Association — Pennsylvania Blue Shield (now Highmark Blue Shield) based in suburban Harrisburg, and Blue Cross of Western Pennsylvania based in downtown Pittsburgh (now Highmark Blue Cross/Blue Shield). The consolidated group is available in 62 of the state's 67 counties. In West Virginia, the company operates as Highmark Blue Cross Blue Shield West Virginia, and in Delaware, it operates as Highmark Blue Cross Blue Shield Delaware. The new company based its head offices in downtown Pittsburgh. On March 28, 2007, Highmark announced it intended to consolidate with Independence Blue Cross of Philadelphia. The combination of the 2 insurers would have created a new company with over 18,000 employees, dual-headquarters in both Pittsburgh and Philadelphia and an economic impact of over $4 billion throughout the Commonwealth of Pennsylvania. On January 22, 2009, Highmark and Independence Blue Cross withdrew their applications to consolidate due to the unacceptability of conditions that the Pennsylvania Insurance Department was going to place upon the merger: to give up either of their well-known "Blue Cross" or "Blue Shield" trademarks. In 2011 the company announced it would buy the financially troubled West Penn Allegheny Health System (WPAHS) for about $500 million, expanding from insurance into owning hospitals. This began a period of conflict between Highmark and UPMC, which had expanded from hospitals into insurance, and caused difficulties for patients to access care at the conflicting institutions. The conflict included a lawsuit by Highmark against UPMC alleging that UPMC over-billed it by $300 million for cancer
