The amendment would allow states to apply for waivers for insurers to let them charge people with pre-existing health conditions higher prices for coverage than healthier people who also buy insurance coverage outside of their job.
The remaining 1/2 of USA citizens (we promise that math adds up!) will see their premiums remain the same as they have been, though there will may be other factors in the bill that affect them individually, especially by age.
Under the current Affordable Care Act, there are regulations that control costs for people with pre-existing conditions.
The CBO's analysis comes as a Senate group is working on their own healthcare bill that is believed to differ drastically from the House version, especially when it comes to Medicaid provisions.
Most of the people losing coverage would be those on Medicaid, which covers low-income Americans, and those with private health care plans.
In their scoring of the previous version, the Office said the bill would cut $337 billion from the federal budget deficit over 9 years, while premiums for individuals purchasing insurance would increase 15-20% in 2018 and 2019.
If the nonpartisan CBO determined that the bill didn't pass muster for reconciliation, Democrats would have been able to hold up the bill with filibuster, which could send the bill back to House Republicans to amend and hold another vote. Over half of those becoming uninsured, 14 million people, would come from the bill's $834 billion in cuts over 10 years to Medicaid, which provides health coverage to poor and disabled people. So, you know, that would be a big change in what CBO is saying is if you are one of those one in six people, you might not have access to affordable health insurance if you're a sicker person.
But the CBO report said the amendment would make it hard or impossible for people in poor health to purchase comprehensive coverage in some states.
Republican Senator Susan Collins said too many people would lose insurance and that older and low-income Americans would be hurt.
Some Republicans, including House Speaker Paul Ryan, said the report showed the legislation met key goals, including driving down premiums and lowering the deficit.
The CBO estimates that about 17% of people will likely end up living in states that request a waiver - and therefore that will allow costs to rise for certain Americans.
