CBO estimates 22 million would lose insurance in a decade under GOP health care bill Congressional Budget Office estimates 22 million would lose insurance in decade.

 -- The Congressional Budget Office estimated that the most recent version of the Republican plan to repeal and replace Obamacare would cut the deficit by $420 billion over the next decade and that 15 million people would lose their health insurance by 2018.

The office also estimated that 22 million fewer people would be insured 10 years from now under the latest plan than would be insured under current law.

The CBO posted its latest analysis early Thursday afternoon, after the Senate Budget Committee posted the GOP’s latest tweaks to its health care bill.

Even before the score was posted on Thursday, Democrats mocked Republicans for having "a new plan every day."

"We have now the plan of the day that's put in front of us," Rep. Richard Neal, the ranking Democrat on the House Ways and Means Committee, said today. "I don't know how CBO has time to do anything else but score plans on a daily basis."

On Wednesday the CBO projected that the GOP's repeal-only measure would cut the deficit by $473 billion over 10 years but would result in 17 million more uninsured Americans in 2018, rising to 32 million by 2026.
