I’ve already noted in a separate post that new Congressional Budget Office projections show President Obama’s health care law will cost $1.76 trillion over 10 years, rather than the $940 billion originally advertised. But there are lots of other moving parts in the CBO’s updated estimates that are worth deeper elaboration.

The big picture takeaway is that due mostly to weaker economic projections, the CBO now projects that more people will be obtaining insurance through Medicaid than it estimated a year ago at a greater cost to the government, but fewer people will be getting insurance through their employers or the health care law’s new subsidized insurance exchanges. Overall spending will be higher than estimated a year ago, but increased revenue from penalties and taxes will more than offset this. Also interesting: CBO now expects two million fewer people to be covered as a result of the health care law than previously projected.
