As lawmakers prepare for intense deficit-reduction negotiations in Washington, the CBO released an analysis that details the consequences of not addressing the fiscal cliff, which describes a series of looming tax increases and spending cuts designed to reduce the nation's federal budget deficit. The report also describes various options for bringing spending and taxes into closer alignment, and criteria that lawmakers and the public might use to evaluate different approaches to deficit reduction. CBO's latest figures confirm what Republicans and Democrats acknowledge -- only selectively -- that health care is a large part of what is driving federal spending and debt. Health care programs are eating up an ever-increasing share of the economy, while tax revenues and other domestic spending are holding relatively steady. CBO also projects that maintaining the Medicare program's current payment rates to physicians and eliminating the expected automatic cuts to nondefense spending early next year would increase federal spending by about $40 billion in 2013 and by $61 billion the following year.
