GLOVES COME OFF: Tenet Healthcare Corp. filed a federal lawsuit against Community Health Systems Inc., which has launched a hostile bid for the fellow hospital operator.
LEFT HOOK: Tenet says Community systematically bilks Medicare by admitting thousands of patients that should only be kept for observation.
BAD BLOOD: Community launched a hostile, $3 billion takeover bid for Tenet recently, after Tenet rejected its buyout offer.
ROPE-A-DOPE: Community calls the allegations unfounded, and says Tenet is trying to distract shareholders with a "scorched earth" defense. It says it conducts business with integrity.
