The basis of this book is to provide an introduction to students on a data entry/billing program found in a medical office. The book provides step by step instructions with multiple screen shots to ensure that the text is easily understood. Typically this text would be used in a course taught in a computer lab with an instructor providing lecture. It is important that the students approach the text at the beginning and work their way through each activity to ensure that instructions are followed and there are not problems with the software. An appendix with basic computer skills is provided to give students a basic computer knowledge, especially for students who struggle with computers. The text does assume that students have some basic knowledge of procedure and diagnosis coding. It begins with basic data entry of patient information and then expands on entering cases and completing billing functions. New to Medisoft Version 14 is the capability of completing UB-04 claims using Medisoft. Appendix 1 teaches students how to utilize this function.
