It has been six months since the highly contested Patient Protection and Affordable Care Act, also called health care reform, became law. Polls show that people remain worried about how the law will affect their health care. There is a lot of talk about big cuts in Medicare, and seniors are worried their coverage will be reduced or that their doctors will no longer accept Medicare. Should they be worried?

The worst news is for people who love their Medicare Advantage plans. This program pays private insurance companies to enroll seniors in managed-care networks. Many plans offer more benefits than “plain” Medicare, such as dental and vision coverage and health club memberships.
