Book excerpt: When you are studying something as intricate, involved, and structured as medical coding, it's worth your time to invest in every study aid you can possibly employ to that end. Since studying is just a way of working to ensure that you can better retain and recall information, a pamphlet is a great way to help you quickly decode various medical codes. While a deck of flash cards may seem useful, using them for a practice such as deciphering medical coding means that you will need a very thick stack; a pamphlet-form study guide takes less space and similar information.
