More than 10.1 million people have enrolled in Medicaid and the Children's Health Insurance Program in the first 14 months since marketplace enrollment began, the Obama administration reported Monday.

Consumers who received too much in federal tax credits when buying insurance on the health law's marketplaces last year got a reprieve of sorts from the Internal Revenue Service this week.

The Obama administration will make historic changes to how the U.S. pays its annual $3 trillion health-care bill, aiming to curtail a costly habit of paying doctors and hospitals without regard to quality or effectiveness.

Of the more than 1 million people who signed up for health care plans through Covered California last year, 92 percent were eligible for enrollment and most of them stayed with their insurance carrier, according to preliminary figures released Wednesday.

One of the greatest promises of the Affordable Care Act is that if you are sick or get sick, health insurers can no longer charge you more or avoid covering you altogether.

California's Medi-Cal program has grown to cover nearly half of the state's children, causing policymakers and child advocates to question the ability of the taxpayer-funded program to adequately serve so many poor kids.
