How frequently are ICD-10 codes revised and updated?

ICD-10 codes are officially revised and updated on an annual basis. This annual update process allows for the incorporation of new medical knowledge, changes in clinical practice, and the introduction of new codes as needed. Updates ensure that the coding system remains relevant and reflects current healthcare practices and terminology.

The annual revision cycle means that healthcare providers, coders, and payers must stay informed about these changes each year to ensure accurate coding and billing practices. This timing helps maintain consistency across health systems and international standards in healthcare classification. By being aligned with annual updates, organizations can prepare for changes and adjust their documentation and coding practices accordingly.
