PITTSBURGH — Health insurer Highmark plans to announce today a partnership with a suburban Pittsburgh health care network. Officials with Highmark and Jefferson Regional Medical Center, just south of Pittsburgh, plan to announce the deal later today. The medical center’s flagship is a 373-bed hospital in Jefferson Hills, but also includes outpatient centers in 10 municipalities south of Pittsburgh, including Uniontown about 40 miles away. State regulators are still reviewing Highmark’s $475 million plan to acquire the Pittsburgh-based West Penn Allegheny Health System, the chief rival to the much larger University of Pittsburgh Medical Center system which dominates western Pennsylvania with hospitals as far away as Erie’s UPMC Hamot.
