Hutcheson Medical Center’s board of directors voted Wednesday night to file for chapter 11 protection, the Chattanooga Times Free Press reported today. Hutcheson has been unable to repay $20 million it borrowed from Erlanger Health System and is facing a threat of foreclosure. In January, Erlanger filed a civil lawsuit against Hutcheson, who was supposed to pay back the $20.5 million loan by Dec. 1 of last year.
