Here is the reply from Rhonda with AAPC (it's in the ICD10 forum):
To ensure employers continue to have confidence in CPC's ability to accurately code the current codesets, once ICD-10 is implemented (thus protecting all 60,000 credential holders), and that those credentials truly represent one's ability to code under the current code set, AAPC members holding a credential will have two years to pass an open-book, online ICD-10 proficiency test.
•You will be given two (2) years to take and pass, beginning October 1, 2012 (one year before implementation of ICD-10) and ending September 30, 2014 (one year after implementation)
•There will be 75 questions
•It will be open-book, online and un-proctored
•Coders will have two (2) attempts at passing for the $60 administration fee
You may take the proficiency exam as many times as needed until September 30th, 2014.
