(CNN) - The Supreme Court's decision Thursday to uphold the Affordable Care Act means that the predictions about how it will affect all Americans remain in place.
Here are some highlights:
The decision leaves in place the so-called individual mandate - the requirement on Americans to have or buy health insurance beginning in 2014 or face a penalty - although many are exempt from that provision.
In 2014, the penalty will be $285 per family or 1% of income, whichever is greater. By 2016, it goes up to $2,085 per family or 2.5% of income.
Because the requirement remains for people to have or buy insurance, the revenue stream designed to help pay for the law remains in place. So insured Americans may be avoiding a spike in premiums that could have resulted if the high court had tossed out the individual mandate but left other requirements on insurers in place.
Millions of young adults up to age 26 who have gained health insurance due to the law will be able to keep it. The law requires insurers to cover the children of those they insure up to age 26. About 2.5 million young adults from age 19 to 25 obtained health coverage as a result of the Affordable Care Act, according to the U.S. Department of Health and Human Services.
Two of the nation's largest insurers, United Healthcare and Humana, recently announced they would voluntarily maintain some aspects of health care reform, including coverage of adult dependents up to age 26, even if the law was scrapped.
