Exactly what I need for the RHIT exam
I have this book in electronic form from one of my college classes but it was always a nightmare to access! Even with lifetime access to it, I can no longer access it since class is over! After spending over $100 on the virtual version I didn’t want to spend too much on the paper version also, so this was perfect. Near perfect condition. Arrived very quickly. Great price. Plus- the person before me included some helpful (yet faint) answers for me!! Thanks for having this book available at an affordable price!

Good resource
I bought this to prepare for my RHIT exam, gives a good run down of most HIM topics but does not go in depth, repeat does not go in depth at times, but good for quick referencing and seeing how different topics relate. This should not be the only resource to prepare for test. as I said, does not go in depth on topics you need to know a lot about on exam. For example devotes one page to a topic that you could easily read a whole textbook about. For example, there is a chapter on reimbursement. You’re going to want to actually review your text book that is solely about reimbursement methodologies, but as I said a good general resource to give a refresher and maybe get a better understanding on how different HIM topics relate. At times presented better information than you could find using a google search.

Expensive, but useful
I rented, then purchased. This book has a lot of concise information not easily found online so is worth the money for accuracy. It is a heavy, hardback book but if kept in an office, is a very useful tool.
