Pediatric ICD-10-CM 2025

The AAP Committee on Coding and Nomenclature (COCN) is responsible for reviewing of all proposed changes to Current Procedural Terminology (CPT) and International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) coding structures to determine whether the Academy will endorse the proposal; participates in the American Medical Association/Specialty Society Relative Value Scale Update Committee (RUC) survey process by validating clinical vignettes, evaluating survey data and deciding on physician work and practice expense relative value units (RVUs) to recommend to the RUC; and serves as a review panel regarding other activities such as identifying Academy positions on the Medicare Resource-Based Relative Value Scale (RBRVS).
