The Congressional Budget Office has released a report on the potential impact of the House GOP health care bill. It estimates that the bill would reduce the federal deficit by $337 billion between 2017 and 2026. It also estimates that compared with current law, 14 million more people would be uninsured by 2018, and 24 million more would be uninsured by 2026.

Just over 28 million Americans were uninsured in the first half of 2016, according to the latest data from the Census Bureau. The CBO estimates that in 2026, there would likewise be 28 million uninsured Americans under current law, compared to 52 million under the Republican repeal and replace plan thus far, also known as the American Health Care Act.

The AHCA is just the first part of the Republicans’ plan to repeal and replace the Affordable Care Act, also known as Obamacare. The bill, written as part of the budget reconciliation process, can only make fiscal-related changes. Part two will include deregulation. Part three will include changes to the law that could not be made in the reconciliation bill.
