Officials: One-Third of Federal Health Insurance Site Still Needs to Be Built

Like, the part where people actually pay for their plans

Between 30 and 40 percent of the IT system for the federal health insurance marketplace must still be built, a top official at the Centers for Medicare and Medicaid Services said Monday.

Henry Chao, the agency's deputy chief information officer, said that a large portion of the behind-the-scenes work has yet to be finished.

"I think it's just an approximation, we're probably sitting somewhere between 60 or 70 percent [completed]," he told the House Energy and Commerce oversight subcommittee.
