Every time a doctor orders an extra test for you, it pushes up your medical costs and - some experts say - contributes to the waste in the nation's $2.2 trillion in health care spending.
While there's much debate about the actual dollar impact of this controversial practice called "defensive medicine," experts agree it's an obstacle to reining in the medical care expenses.
Defensive medicine occurs when a doctor orders tests or procedures not based on need but concern over liability, explained Dr. Alan Woodward, former president of the Massachusetts Medical Society (MMS) and vice chairman of its committee on professional liability.
Anderson Cooper goes beyond the headlines to tell stories from many points of view, so you can make up your own mind about the news. Tune in weeknights at 8 and 10 ET on CNN.
