Tenet May Face Up to $6 Billion in Liabilities

Tenet Healthcare Corp. could face as much as $6 billion in legal liabilities to the federal government from the way it charged to treat Medicare patients with unusual costs, a shareholder group said.

The Tenet Shareholder Committee holds about 25,000 shares and is urging a change of top management.

Santa Barbara-based Tenet has drawn regulatory scrutiny over "outlier" payments that the federal health plan covering more than 40 million elderly uses to reimburse hospitals.

Tenet declined to comment.
