I am due to take my CPC exam in WA State in September. I seem to be getting conflicting information regarding the time period you must wait before attempting to re-take the exam should you fail the first time. Some say 90 days, others say there is no waiting period, others say the waiting period is for the AHIMA not AAPC proctored exams, some say it varies by state, etc....I have googled and still cannot find a conclusive answer, so if you someone has an ABSOLUTE answer it would be greatly appreciated!
