On March 11, exactly two months earlier, the non-partisan CBO reported the estimated increase for discretionary spending could exceed $55 billion.
Douglas Elmendorf, the CBO director, said the latest report "updates and expands" on the previous report. He noted that assessing effects on discretionary spending was speculative because such appropriations require congressional action, and could be larger or smaller than initially anticipated.
The health care legislation was estimated by CBO to cost $940 billion over 10 years and reduce the federal deficit by $143 billion over the same period.
Increased costs in discretionary spending would not necessarily offset the estimated deficit reduction. Congress requires most discretionary spending to have available resources under so-called "pay to go" rules.
According to the CBO report, the estimated higher costs would come from increased administrative expenses for the Internal Revenue Service and Department of Health and Human Services, as well as grants and other programs contained in the health care bill.
