This bill makes extreme changes to the American health care system. From a high level, what the bill aims to do is reduce restrictions on the level of care insurance companies are required to provide their beneficiaries. The result of this will be less expensive options for health insurance, but with significantly weaker overall coverage. As it stands, 24 million Americans will lose coverage under the American Healthcare Act, mostly from the proposed roll back of Medicaid.
Here are some of the changes included in the AHCA:
Some remnants of the Affordable Care Act remain, such as the ability for adult children (up to age 26) staying on their parent's insurance plan.
In order for the Affordable Care Act to be officially replaced by the American Healthcare Act, the bill still needs to pass through the Senate and the scrutiny of the Senate parliamentarian. The Senate Parliamentarian, Elizabeth MacDonough, will ultimately decide if the bill counts as a reconciliation bill. If it does, then only 51 votes are required to have the bill pass through Senate. Otherwise, it will require 60 votes, an unlikely scenario as it would require Senate Democrats to vote favorably.
