Many states require insurance - especially auto insurance - to protect victims of negligent drivers who cause accidents. But some states don't require physicians and healthcare providers to have medical malpractice insurance to protect their patients. Think of it - a doctor's negligence injures or kills a patient. The patient needs medical care and treatment, can't work, and has a permanent injury. Or worse, his family who relied on him for love, support and income, is left with nothing - even in cases of blatant medical errors like prescription errors, surgery on the wrong body part, or failing to tell a patient about life threatening test results like cancer or deep vein thrombosis (DVT). This article from the South Florida Sun Sentinel, describes the situation.
