ACA Signups, 1/21/14: Med/CHIP 6.32M. CNBC Just Now: Med/CHIP "more than 6.3M"

Yes, this is self-serving and smug. I really don't care at the moment:

Enrollment in Medicaid spiked in December, aided by Obamacare exchanges and an expansion of the government-run health coverage program for the poor in 25 states...

By the end of December, more than 6.3 million people were determined to be eligible for Medicaid or CHIP, the program covering children, through state-run agencies and state-based Obamacare exchanges, according to a Centers for Medicare & Medicaid Services report released Wednesday.

That tally does not include the 750,000 or so people who were determined eligible in Medicaid through the federally-run Obamacare exchange HealthCare.gov.

Adding the two enrollment numbers together equals more than 7 million Medicaid-eligible determinations. But some of the determinations made by HealthCare.gov may be duplicative of state-based decisions.

As it happens, if you look at the Medicaid/CHIP spreadsheet, I deliberately left out about 620,000 Medicaid enrollees from the total because I suspected they would otherwise be double-counted.

I particularly like this part later on:

Health care analyst Timothy Jost, a professor at the Washington and Lee University School of Law, said that high percentage is "the key number" and suggests that a big chunk of the Medicaid sign-up reported Wednesday are due to new enrollees.

But how big a chunk is difficult, if not impossible, to figure out from the CMS data, Jost said.

"The numbers are just so confusing," he said.

Took the words right out of my mouth.
