There are numerous ways to prepare for an AAPC certification exam. You may select from online training or classroom training. There are study guide books, online courses and online practice exams. Beginning coders and billers need to know medical terminology and anatomy before starting any medical coding or billing curriculum. More experienced coders might only need a study guide. All future certification exam takers will benefit from AAPC’s online practice exams, which are developed by the same people that created the certification examinations and simulate the format, difficulty level, and time constraints of the actual certification exams.
