BALTIMORE (AP) — Medicare's war on fraud is going high-tech with the opening of a $3.6 million command center that features a giant screen and the latest computer and communications gear. That's raising expectations, as well as some misgivings.

The carpeting stills smells new at the facility, which went live a week ago in a nondescript commercial office park on Baltimore's outskirts. A couple dozen computer workstations are arrayed in concentric semicircles in front of a giant screen that can display data and photos, and also enable face-to-face communication with investigators around the country.

Medicare fraud is estimated to cost more than $60 billion annually, and for years the government has been losing a game of "pay and chase," trying to recoup losses after scam artists have already cashed in.
