The U.S. Senate is now considering a series of so-called "fixes" to the new health care law.
The measure will eliminate a special Medicaid deal for the state of Nebraska, known as the "Cornhusker kick-back."
It will also offer more generous drug coverage for seniors and provide larger subsidies for lower-income people.
The fix-it bill is likely to pass the Senate by the end of the week as it only needs 51 votes.
Meanwhile, Republican lawmakers are using the debate to add amendments in hopes of derailing the process.
"I know we can't fix it really because it's such a terrible bill," Sen. Judd Gregg, R-N.H, said.
"I think the new slogan will be 'repeal and replace.' Repeal and replace." Minority Leader Sen. Mitch McConnell, R-Ky, added.
If so much as a comma is changed, the bill will have to go back to the House for another vote.
However, the administration seemingly unfazed by GOP threats, has already turned its attention to selling the plan to the American public. President Obama is scheduled to kick off the public relations campaign in Iowa on Thursday.
