NEW YORK (AP) — CGI Group Inc. said Thursday it will help build the federal government's health insurance exchanges as part of a contract with Medicare worth up to $93.7 million.

CGI Group, a Canadian information technology services company, said its CGI Federal Inc. unit will work with the Center for Consumer Information and Insurance Oversight, which is part of the Centers for Medicare and Medicaid Services. The initial contract its worth $55.7 million over two years. It includes three one-year options, and if all of those options are exercised, the value of the deal could reach $93.7 million.

The health insurance exchanges are part of Patient Protection and Affordable Care Act, the March 2010 health care overhaul law. Millions of uninsured Americans will be able to buy private health insurance through the online exchanges starting in 2014. Taxpayer funds will cover the cost of premiums purchased through the exchange.
