There is a lot of confusion over the multiple incarnations of the Republican health care plan, but in the end, how different are they?

We looked at key numbers in six of the proposed plans — three from the House and three from the Senate — that were analyzed by the Congressional Budget Office, a nonpartisan group of economists and statisticians.

The increases in the number of uninsured are nearly the same.

One of the most important variables — how many people would be without health coverage — is essentially the same in five of the plans that repeal and replace the Affordable Care Act. Those plans would increase the number of uninsured by more than 20 million people in 10 years.

How the number of uninsured would increase

60 million uninsured Senate partial repeal First two House bills Final House bill 50 Revised Senate bill Initial Senate bill 40 30 Under the Affordable Care Act 20 10 2017 2026 60 million uninsured Senate partial repeal First two House bills Final House bill 50 Revised Senate bill Initial Senate bill 40 30 Under the Affordable Care Act 20 10 2017 2026 Note: The uninsured numbers would stay the same as the first under the second House bill that was scored.

The uninsured would increase by more than 30 million people under a sixth plan, a partial repeal of the Affordable Care Act with no replacement. This plan is similar to a 2015 repeal bill that was vetoed by President Barack Obama in 2016.

Republican leaders in the Senate say they will vote this week on whether to start debating a health care bill, but as of Friday it was unclear which bill they would take up.

The six versions that have been analyzed by the C.B.O.

Plan Description Initial House bill American Health Care Act. Second House bill First plan scored with amendments, including changes to taxes and Medicaid. Final House bill Passed on May 4. Initial Senate bill Better Care Reconciliation Act of 2017. Revised Senate bill Latest Senate bill. Senate partial repeal Repeals coverage provisions.

The House produced multiple variations of their bill before narrowly passing one on May 4 with no Democratic votes.

The Senate has released four different draft bills so far, three of which have been analyzed by the budget office.

The fourth Senate draft, which includes an amendment initiated by Senator Ted Cruz of Texas, is not shown in the charts in this article because it has not yet been evaluated by the budget office.

The different versions take a variety of approaches to providing health coverage for middle-income Americans who don't get insurance through work or a government program.

The six versions would make deep cuts to Medicaid.

With each new version, changes were made to appease lawmakers with sharply different priorities in an effort to pick up a few more votes.

A common thread in all the House and Senate versions, however, is that people with Medicaid coverage would be the largest group to be affected.

How many fewer people would have Medicaid in 2026

Compared to the number covered if the Affordable Care Act stays in place.

Initial House bill 14 million 14 million Second House bill 14 14 Final House bill 14 14 Initial Senate bill 15 15 Revised Senate bill 15 15 Senate partial repeal 19 19

Under the Affordable Care Act, 31 states and the District of Columbia expanded Medicaid coverage to poor adults who were previously uncovered. Republicans in Congress are seeking to sharply curtail federal support of the expansion, likely causing many states to end it.

In all the bills, the largest savings — more than $750 billion over 10 years — would be achieved through deep cuts to the program.

Total amount the federal government would save from Medicaid cuts through 2026

Initial House bill $880 billion $880 billion Second House bill $839 $839 Final House bill $834 $834 Initial Senate bill $772 $772 Revised Senate bill $756 $756 Senate partial repeal $842 $842

Most of the plans would also make changes to the structure of the entire Medicaid program, including spending reductions that the C.B.O. thinks are likely to cause coverage reductions over time.

The cost of premiums would eventually fall in five of the plans.

Republican lawmakers have long cited rising premiums as one of the main reasons for repealing the Affordable Care Act.

In all plans scored by the C.B.O. — except the partial repeal bill — average insurance premiums would rise in the first year, but eventually become lower than the current law by 10 percent to 25 percent.

How average premiums would change

Relative to the level if the Affordable Care Act stays in place.

Plan In 2018 In 2026 Initial House bill 15% to 20% higher 10% lower Second House bill 15% to 20% higher 10% lower Final House bill 20% higher 20% lower in some states Initial Senate bill 20% higher 20% lower Revised Senate bill 20% higher 25% lower Senate partial repeal 25% higher 100% higher

The C.B.O. said that the changes would largely result from increases in average insurance deductibles and reductions in the number of older Americans with coverage.

The biggest difference among the plans is how much they would lower the deficit.

The one place where there is wide variation among the plans is in how much money the federal government would ultimately save over 10 years.

How much money the federal government would save in 10 years

Initial House bill $337 billion $337 billion Second House bill $150 $150 Final House bill $119 $119 Initial Senate bill $321 $321 Revised Senate bill $420 $420 Senate partial repeal $473 $473

The final House bill, which was approved, would save the government less than the original House bill because lawmakers had to add 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.

The revised Senate bill, however, would achieve larger savings than the initial Senate version because it would keep two taxes on high-income earners that were eliminated earlier.
