Since the code sets for each coding book are updated every year, it's essential for coders to have the current year’s books to ensure accurate performance. Reporting wrong codes can lead to denied claim submissions and substantial penalization. It's clearly very important to get an education on the annual code set updates and to obtain new code books every year.
Additionally, for individuals facing financial constraints, AAPC provides alternative solutions like free access to current-year eBooks during exams, ensuring accessibility to the latest code updates without the need to purchase physical books.
Study Practices and Preparation Tips
Practicode aligns with updated coding standards, providing an excellent tool for practice. Although older editions may be used for study, using books updated to the current revision is strongly advised. Transitioning to updated books (e.g., from 2025 to 2026) often represents a minor change, but taking the time to learn any differences is essential for success.
All AAPC exams are based on the current calendar year's code sets, so we strongly suggest you use the current year's books. The previous calendar year’s books may be used on an exam, but you would be at obvious disadvantage doing so. The upcoming year's books are not allowed for exam use. The exams are updated every January for the new code sets.
Typically, new coding books become active for exams following a blackout period. For instance, the 2026 guidelines will be applicable from January 15, 2026.
Reference Book Formats and Accessibility
AAPC ensures its reference books are accessible in multiple formats to suit candidates' preferences. The 2026 editions, for example, will be available in both print and eBook formats. This flexibility allows individuals to choose the format that best supports their exam preparation.
In other words, all exams administered in 2026 will be based on the 2026 code sets, and we strongly recommend using the 2026 code books. While code books from 2025 can be used for the 2026 exams, this introduces a risk of mismatched codes due to updates. Exams conducted before March 2, 2026, may still feature 2025 coding updates due to transitional delays, offering some flexibility. However, code books from 2027 may not be used on 2026 exams.
