Diagnosis Code Categories

The VEHSS system uses diagnosis codes to identify vision and eye disorders in all administrative claims and electronic medical registry data. Diagnosis codes are based on the International Classification of Diseases (ICD) system. All ICD-9 and ICD-10 codes related to vision, the eye, and ocular adnexa are categorized in a two-level categorization system using mutually exclusive categories and sub-groups to provide more efficient estimates of key vision and eye health outcomes. The VEHSS Diagnosis Code Categories and Crosswalk Cdc-pdf[PDF – 2.1 MB]External spreadsheet includes the ICD-9 and ICD-10 codes mapped to each category and subgroup.
