In an effort to build support, Baucus had made several changes for Democrats and Republicans in opposition to certain provisions in the measure.
Senate Majority Leader Harry Reid (D-Nev.) filed cloture on the bill Wednesday, setting up a Friday vote. But it wasn't known Thursday evening if an agreement could be reached to vote on the bill this week.
The bill cuts an extra $25 from weekly unemployment benefits checks, part of the February 2009 economic stimulus, saving $5.8 billion.
Another $16.4 billion is saved by postponing the payment cuts to doctors through November instead of the 19 months included in the House-passed measure.
The House passed a $115 billion version of the measure before the Memorial Day recess as two separate bills -- one with all of the tax extenders and unemployment benefits and another with that dealt with the $23 billion Medicare 'doc fix' that would last 19 months.
