The high-stakes, seven-year battle to build the first hospital in Fort Mill, SC, could be nearing an end. Tenet Healthcare Corp., Novant Health and Carolinas HealthCare System plan to file the last required paperwork today in their bids to be the main healthcare provider in northern York County. S.C. regulators will decide by early September who gets to build. Appeals could prolong the fight. It's a dispute that's been unusually long, public - and strategic. Tenet, which runs Piedmont Medical Center in Rock Hill and is the only for-profit entity among the three, declares it will lose millions if one of the Charlotte titans wins. Meanwhile, continued growth is key for rivals CHS, which runs Carolinas Medical Center, and Novant, which owns Presbyterian Healthcare.
