As a result of the Affordable Care Act, many health insurance plans are now required to pay in full for preventive health services, such as well visits and routine checkups. WebMD readers have asked many questions about preventive care and the services now available as a result of health care reform. Here are answers to the five most commonly asked questions.

Q: Do all health plans have to provide free preventive care? A: No. Insurance plans that were already in place when health reform became law on March 23, 2010, are considered grandfathered and won't be required to comply with a number of provisions of the new law. However, the expectation is that most health plans will lose their grandfathered status due to significant changes in their benefit design by 2014 and be required to comply with all aspects of the new law.

Q: Does health care reform include provisions to reward good health behaviors, such as fitness, weight loss, and regular preventive screenings? A: Yes. One way the new law rewards people for healthy behaviors is through employer-sponsored wellness programs. Common wellness programs offered by employers include smoking cessation, nutrition, disease counseling, and stress management. By 2014, the law will allow employers to increase employee incentives for participating in wellness programs from the current 20% to 30% of the total premium. For employees, that can translate to money in your pocket in the form of reduced insurance premiums, lower co-payments and deductibles, gift cards, and even cash.
