Relatively few people have enrolled in new health insurance plans since the Affordable Care Act exchanges launched this month. But some health care experts say it's early days yet — and that getting the right proportion of healthy, young new enrollees is just as important as how quickly people sign up.
The Congressional Budget Office projects that 7 million people will buy health insurance for 2014 through the new exchanges, integral to the implementation of the government's new health care law.
