On June 28, 2012, the Supreme Court issued a decision that essentially made the expansion of the Medicaid program under the Affordable Care Act (ACA) a state option rather than what appeared to be mandatory for states that wanted to continue receiving federal matching funds for any part of their Medicaid program.
CBO and the staff of the Joint Committee on Taxation (JCT) have prepared two analyses that take into account that decision:

On June 28, 2012, the Supreme Court issued a decision that essentially made the expansion of the Medicaid program under the Affordable Care Act (ACA) a state option. CBO and the staff of the Joint Committee on Taxation (JCT) have updated their estimates of the budgetary effects of the health insurance coverage provisions of the ACA to take into account the Supreme Court decision. This report describes those new estimates, how they were derived, and how they differ from the previous ones. The figures do not include the budgetary impact of other provisions of the ACA.
cost estimate

CBO and the staff of the Joint Committee on Taxation (JCT) have estimated the direct spending and revenue effects of H.R. 6079, the Repeal of Obamacare Act, as passed by the House of Representatives on July 11, 2012. H.R. 6079 would repeal the Affordable Care Act (ACA), with the exception of one subsection that has no budgetary effect. This estimate reflects the spending and revenue projections in CBO’s March 2012 baseline as adjusted to take into account the effects of the recent Supreme Court decision regarding the ACA.
