The answer is, not much, AND, a lot. The confusing answer, I know. Well, medical malpractice is a sub-set of personal injury law. For instance, when a doctor negligently injures one of his patients, that is medical malpractice. This is like a driver who negligently injures another driver by rear ending him, an ordinary personal injury matter. Most lawyers who claim to be “medical practice lawyers” have handled or handle, ordinary personal injury cases. Your typical personal injury case doesn’t require the monetary or time investment of a medical malpractice case. Medical malpractice cases often take several (3-5) years to investigate and prosecute. Your usual personal injury case does not (or should not). Also, to fund the investigation and prosecution of a medical malpractice case may cost the lawyer $50,000 to several hundred thousand dollars in out-of-pocket expenses. Your typical personal injury case does not cost nearly that much. Handling a medical malpractice case often requires extraordinary knowledge of the medicine involved whereas a typical injury case probably does not. Regardless of what type of case you or a loved one has; it is important to find a lawyer who has a track record of success in the sub-set of law that your case involves.
