The Supreme Court's decision on June 28 to uphold the Affordable Care Act will expand health care to a majority of Americans, and protect them against the worse insurance company abuses.

About 32 million Americans are expected to gain health insurance under the law starting in 2014, when it takes full effect.

Here's what health reform means to Americans:

Lets young adults stay on their parent's insurance plan until age 26

Ends insurance company power to cap the amount of care a person can receive in their lifetime

Stops insurance companies from canceling coverage when someone gets sick

Lowers the cost of care for those on Medicare and helps seniors save money on their medication

Requires insurance companies to cover preventive services like mammograms free of charge

Increases penalties for Medicare fraud

Stops insurance companies from denying coverage to children under 19 with pre-existing conditions

Ends insurance company power to jack up rates without justification

Provides rebates from insurers who spend too much on CEO bonuses or ads

Gives tax credits to small business owners so they can afford to offer health care to employees

Builds and improves hundreds of community health centers

Gives patients the right to appeal an insurer's decision

Gives working Americans tax credits so they can afford insurance beginning in 2014

Ends discrimination against adults with pre-existing conditions beginning in 2014

Prevents insurance companies from charging women more than men, and overcharging those who need care the most beginning in 2014

Creates state-based marketplaces where people can easily compare and shop for insurance beginning in 2014
