520.9
ICD-9-CMThis code signifies a general, unspecified problem with how teeth form or emerge into the oral cavity. It covers a broad range of developmental anomalies or eruption disturbances when the specific nature of the issue is not documented.
Use this code when documentation indicates a tooth development or eruption issue, but lacks specific details such as hypoplasia, impaction, or premature eruption. This code is appropriate when the provider notes "abnormal tooth development" or "eruption problem" without further elaboration.
