I am sorry, I meant no offense to those who have the CCA credential. It is just that I don't recommend taking it especially with the hope that it will assist with employment. And, after all, why else do students look to take and pass these tests, if it is not in hopes of improving their job prospects and their potential in the eyes of employers. As you know and have personally experienced, employers do not recognize the CCA like they do the CCS, CCS-P or even CPC. So to me and several other students and coders I have spoken with, it seems more reasonable to save up their money to take an exam that will count instead of having to save up for two exams.
As for the CCS-P exam, the top book that I recommend for studying is a textbook by Lynn Keuhn: Coding and Reimbursement for Physician Services. This text will cover information on the multiple choice part of the CCS-P as well as give you a full review of CPT and HCPCS. If you need information on ICD-9, there is a textbook called ICD-9 Coding for Physician Offices and it is by AHIMA also and I recommend it for brushing up on ICD-9 if needed. These two textbooks should give you both the text and practice that you need before working with the Prep book by AHIMA.
It is hard for me to recommend any test prep books out there because they just are lacking in so many ways, although they do have some benefit. The best prep book for the CCS and CCS-P is really the Clinical Coding Workout by AHIMA. It has detailed explanations like I have not seen or heard of in any other book out there.
My exam echoes is currently posted to my website as a complete multiple choice study guide for the CCS. I hope to turn out another set of issues that will serve as a complete multiple choice study guide for the CCS-P and a refresher on key CPT coding principles later on this year.
