Here are key findings from the Congressional Budget Office’s analysis of the Republican health care overhaul bill passed by the House on May 4.

The bill would save the federal government $119 billion in a decade .

The largest savings would come from cutting Medicaid and reducing tax credits for middle-income insurance buyers.

Projected cumulative change in deficit, in billions

Because Republicans are using a special legislative process to avoid a filibuster in the Senate, the bill had to comply with special rules. They include saving the federal budget at least $2 billion over 10 years.

An initial version of the bill would have saved the federal government $337 billion over a decade, and a subsequent version would have saved half that amount. House Republicans pulled an earlier bill from the floor because they did not have enough votes to pass it.

In the final bill, however, lawmakers added more spending in various areas to get enough votes to pass, including $8 billion over five years to help cover insurance costs for people with pre-existing conditions.

One of the bill’s most expensive items is a provision that would eliminate about $600 billion in taxes imposed under the Affordable Care Act, including taxes on investment income, prescription drugs and indoor tanning.

23 million more Americans will be uninsured in 10 years.

The budget office projected that in 2018, the number of uninsured would increase to 41 million and would continue to grow. In 10 years, it would become closer to what it was before the Affordable Care Act, President Barack Obama’s signature health law, took effect.

Number of uninsured

People with Medicaid coverage would take the largest loss. In a decade, 14 million fewer people would be enrolled in the program.

The C.B.O. estimates that the increase in the number of uninsured would be disproportionately larger among older people with low incomes.

Cost of insurance could rise more than nine-fold for some older people with low incomes.

The House bill included last-minute amendments that let states seek changes to certain insurance regulations.

The C.B.O. estimates that premiums could go down about 10 to 30 percent for people in states that make moderate changes to these regulations. This is largely achieved by offering skimpier plans and pricing out the old and sick from the insurance market.

Premiums would become significantly higher for older people with low incomes, according to an example cited in the C.B.O. report, whether or not states made some changes to regulations, and even higher in states that did not.
