Two major healthcare mergers could be in trouble amid competition concerns

Two major health insurance deals that would reshape the industry's landscape -- Anthem Inc.'s purchase of Cigna Corp. and Aetna Inc.'s deal to acquire Humana Inc. -- appear to be in trouble amid concerns they would reduce competition. The Justice Department, which has been reviewing both transactions, is preparing lawsuits to block them, Bloomberg News and the Wall Street Journal reported Tuesday. A decision whether to file the suits could come as early as this week, and the companies could fight in court or agree to settle, the reports said. A Justice Department spokesman declined to comment. Shares of the four companies fell 2% to 4% on Tuesday.
