Tenet Healthcare Corp., the third- largest U.S. hospital company, reported fourth-quarter income helped by higher admissions and reaffirmed its 2013 forecast.

Adjusted earnings before interest, taxes, depreciation and amortization of $336 million beat analysts’ estimates and the company’s forecast, Dallas-based Tenet said Tuesday in a statement. Earnings excluding one-time items were 52 cents a share, 15 cents lower than the average of 19 analysts’ estimates compiled by Bloomberg.
