I purchased this book hoping I will learn more about the medical billing industry, instead it focused too much on teaching someone how to build a home-based business, which I can find another book less than its current price. There are really just 20 pages talking about what you need to be aware in the medical billing industry, I did not gather much. I do not recommend this book.
