Without releasing any demographics or figures on how many enrollees have actually paid their premiums, the Centers for Medicare and Medicaid Services (CMS) on Friday said in a blog post that health care enrollment on the state and federal marketplaces had reached 3 million.

That's a boost of about 800,000 since figures were released in late December, but it's still short of the Obama administration's stated goal of 3.3 million on board by Jan. 1, 2014, with 7 million expected by March 31.

Marilyn Tavenner, a CMS administrator, announced the preliminary tally in a blog posting yesterday. She forecast that enrollment through new federal and state health insurance marketplaces would continue to grow in coming weeks as a public outreach campaign accelerates.

The CMS also said another 6.3 million Americans would qualify for Medicaid of CHIP (Children's Health Insurance Plan) under the Affordable Care Act (ACA)
