AHIMA does not allow any kind of handmade tabs, sticky notes, or loose materials. The PREPRINTED tabs in the front of your CPT book that can be stuck on the pages are not handmade, but are intended to be used with your CPT book, so they should be fine. You would not be able to use the blank ones if you wrote on them. Handwritten notes are acceptable as long as they are not copied guidelines or reference material.
The AAPC does allow handmade tabs that are inserted, stapled, pasted, mood, or tap ed as long as the intent of the tab is to mark a page with words or numbers, not to provide supplementary information. No materials other than tab dividers maybe inserted, stapled, pasted, or anything else in the books. Handwritten notes are acceptable, as long as they pertain to "daily coding activities."
As you can see, the organizations have slightly different requirements. If you use the preprinted tabs from the front of your CPT manual, you should be able to use them for both exams.
You can find the exam requirements on the organizations' websites. You definitely want to examine all that material closely well in advance of your exam.
