520.4
ICD-9-CMThis code represents various anomalies in the development of teeth, encompassing issues with the quantity, structure, or morphology of dentition. It covers conditions where teeth fail to form correctly, are misshapen, or are present in abnormal numbers.
Use this code for diagnoses such as hypoplasia of enamel, supernumerary teeth, anodontia, or gemination. Documentation should clearly indicate a developmental disturbance affecting the tooth structure or number, rather than acquired conditions.
