The Prime Healthcare Services hospital chain has acknowledged it is the target of two federal investigations: a U.S. Justice Department probe of its Medicare billings and an inquiry into alleged violations of patient confidentiality laws. The San Bernardino County-based company disclosed the investigations in a Jan. 2 filing with the state health department in Rhode Island, where Prime hopes to buy its 22nd hospital. Prime's filing marked the first time the company has said it is facing a federal investigation.
