Effective in 2010
Dependent coverage: Children can stay on their parents' policies up to age 26. As of June 2012, 3.1 million young adults had gained insurance - a 75 percent rise in the proportion of insured adults ages 19 through 25.
Preventive benefits: New health plans must provide, without cost-sharing, certain preventive health services including vaccinations, mammograms, prenatal care, and contraception. By February 2012, about 54 million Americans had received preventive care under the law - and religious groups had filed lawsuits challenging the birth-control benefits.
Lifetime limits: Health plans can't put lifetime dollar limits on coverage.
Preexisting conditions: People who can't get health insurance because of continuing health problems could be covered by Preexisting Condition Insurance Plans (PCIP), a transitional program that will expire when insurance exchanges are available in 2014. As of April 2012, 67,000 people had enrolled in PCIPs, including more than 5,000 Pennsylvanians and about 900 in New Jersey.
Small-business tax credits: Employers with up to 25 employees, each earning less than $50,000, began getting tax credits for providing health insurance to workers. In 2014, the credits will rise to 50 percent of employer costs if coverage is bought through an insurance exchange.
Indoor tanning: A 10 percent tax was imposed on tanning services.
Medicare prescription drugs: Medicare recipients began receiving annual rebates or discounts on prescription drugs that ultimately will close the "doughnut hole" coverage gap. As of June 2012, more than 5.2 million seniors and disabled people had received checks and discounts worth $3.7 billion.
80/20 rebates: Insurers must spend at least 80 percent of consumers' premium dollars on medical care, and no more than 20 percent on administrative costs - or give customers a rebate for the difference. As of June 2012, 12.8 million Americans, including 576,000 Pennsylvanians, got $1.1 billion in rebates; the average per family was $151.
Medicare Preventive benefits: Co-pays and other cost-sharing are eliminated for Medicare-covered preventive services such as colon cancer screening.
Income-related premiums: Medicare recipients whose incomes exceed a certain threshold must pay higher premiums.
Pharma Industry: Drugmakers pay new fees in January to help fund the law.
Hospital readmissions: Beginning in October, Medicare payments will be cut to hospitals with excessive, preventable readmissions.
Medicare tax increase: The tax rate on wages for Medicare hospital coverage rises from 1.45 percent to 2.35 percent on earnings over $200,000 for individuals and $250,000 for married couples.
Individual mandate: Most citizens must be covered or pay a phased-in tax penalty.
Insurance exchanges: These online sites to buy insurance must be established by Jan. 1. Track your state at statehealthfacts.org.
Curbs on insurers: Annual coverage limits are prohibited, and insurance must be renewable regardless of health status.
Employer penalty: Employers with more than 50 employees who do not offer health coverage will be assessed a per-worker fee. - Marie McCullough
