ICD-10 Tumor Site Map

    We updated our tumor site map to align with the active FY 2022 ICD-10 diagnosis code set.

    Prior to this, Advisory Board conducted a comprehensive overhaul of our Tumor Site Map in FY 2019 to align with the ICD-10 diagnosis code set based on several years of historical ICD-10 claims data. We made significant changes to the Tumor Site Map’s structure and even to some of the relationships between specific codes and tumor sites or sub-tumor sites.

    To learn more about the new structure and methodology implemented in FY 2019 as well as the minor updates made in subsequent years, we recommend reviewing the User Guide first.
