More than 2.1M people have signed up for Obamacare-mandated health insurance, which has gone into effect today. That's an addition of 1.6M consumers in December, but somewhat below the 3.3M that was initially projected.
Administration officials also don't know how many people have paid, while insurers haven't received all the information they need about those who have bought plans. As a result, much confusion is expected when patients turn up for appointments, a situation the government is hoping to help alleviate with a toll-free call center.
Around 3.9M people are judged eligible for Medicaid and a related children's insurance program, although it's not known how many have signed up. Another 3M young Americans have coverage under their parents' plans.
