Presenters that teach the same course to different audiences will receive CEUs for their first presentation only. They will use the same certificate and index number to receive the same CEUs for presenting as the attendees do for attending. AAPC will accept up to 16 CEUs for first time presentations per core credential, per two-year renewal period, for presentations specific to the credential. An index number can be submitted only one time. AAPC does not award CEUs for time spent in preparation.
