It looks like the beginning of the end for Obamacare as we know it.

After years of vowing to repeal the Affordable Care Act, as it is formally known, Republican lawmakers in both chambers of Congress have now passed a bill that will make it easier to gut the law.

Because they are using a special budget process, Republicans won’t be able to repeal all provisions of the health law. But it seems like a good time to look at the major changes Obamacare brought to health care, which of those changes may now disappear, and what might replace them.

An important note: We still don’t know the details of a repeal bill, and passage is not guaranteed. But Republicans passed a similar package in 2015, vetoed by President Obama, that provides a rough template. Republicans have also said they hope to make further changes through additional legislation. We’ll provide updates when new legislative language arrives, expected in several weeks.
