Those amounts do not reflect the total budgetary impact of the ACA. That legislation includes many other provisions that, on net, will reduce budget deficits. Taking the coverage provisions and other provisions together, CBO and JCT have estimated that the ACA will reduce deficits over the next 10 years and in the subsequent decade.

Assuming that H.R. 6079 is enacted near the beginning of fiscal year 2013, CBO and JCT estimate that, on balance, the direct spending and revenue effects of enacting that legislation would cause a net increase in federal budget deficits of $109 billion over the 2013–2022 period. Specifically, we estimate that H.R. 6079 would reduce direct spending by $890 billion and reduce revenues by $1 trillion between 2013 and 2022, thus adding $109 billion to federal budget deficits over that period.

And in fact, the CBO now projects that the very expensive health insurance coverage provisions will cost $49 billion less than had been previously estimated. And the new CBO report then referenced its 2012 letter to John Boehner (pdf) , which estimated the effect of the Republican bill H.R. 6079, which would have repealed Obamacare:That Obamacare would add to the deficit is one of the GOP's most insidious zombie lies. The CBO has been explict, both in its regular reports and in its letter sent specifically to John Boehner. The facts are clear, and must be repeated at least as often as are the zombie lies themselves. The truth is that Obamacare does not add to the deficit, it reduces it. The truth is that repealing Obamacare would not reduce the deficit, it would increase it.

The Republicans are lying. Again. The ostensible rationale for their attack on the ACA is exactly backward. Obamacare reduces the deficit. With Obamacare, the president and the Democrats not only are expanding the availability of health insurance, they are reducing the deficit.
