Health Exchanges to Be 'Up and Running' by Oct. 1

The government is "on track" to open new online insurance exchanges, a provision of President Barack Obama's health-care reform law, by Oct. 1, U.S. Chief Technology Officer Todd Park told CNBC on Monday.

The Obama administration has already delayed these insurance offerings for small businesses, and a recent report by the watchdog Government Accountability Office called into question whether new insurance marketplaces for millions of individuals would meet an Oct. 1 deadline for open enrollment.

But Park, the president's tech point-person, said in a "Squawk Box" interview, "They're going to be up and running on October 1." He said he's seen the testing on the Web technology to deliver these exchanges, and "things are on track to actually make that happen."

Last week, the Obama administration said it will not require employers to provide health insurance for their workers until 2015, in a move that delays a key provision of the health-care law by a year.
