NEW YORK — Hospital operator Tenet Healthcare Corp. has agreed to pay $42.8 million to resolve allegations it overbilled Medicare for the treatment of patients who needed intense inpatient rehabilitation.

The Dallas company said Tuesday that the settlement resolves inquiries by the Department of Justice, Department of Health and Human Services and the U.S. Attorney’s Office for the Northern District of Georgia.

The allegations involve the admission of patients at 25 facilities from May 2005 to December 2007. The Justice Department said Tenet billed Medicare for patients who did not meet the standards for admission to inpatient rehabilitation facilities. Medicare pays those facilities at a higher rate because patients require more difficult rehabilitation and more medical supervision than patients at other types of facilities.


Dunn resigns as Best Buy CEO; search begins

MINNEAPOLIS — Best Buy Co. CEO Brian Dunn has resigned from the electronics retailer.

Best Buy said Tuesday that it was a mutual decision and there were no disagreements with Mr. Dunn on any matter relating to operations, financial controls, policies or procedures. Its stock gained 52 cents, or 2.3 percent, to $23.17 in morning trading.

The announcement came a little less than two weeks after Best Buy unveiled a restructuring plan. The chain plans to close 50 of its U.S. big-box stores, open 100 small-format stores and cut $800 million in costs over the next five years.

Best Buy, whose sales have been stung by competition from online sellers such as, is trying to become nimbler to avoid the fate of former rival Circuit City, which filed for bankruptcy protection in 2008. Traditional electronics retailers are suffering as more people buy gadgets online or at discount stores.

Board member Mike Mikan will serve as interim CEO while the company searches for a permanent replacement. Best Buy said it already has created a search committee for identifying and choosing its new CEO.
