Anodontia

This code represents the congenital absence of all teeth, either primary (deciduous) or permanent. It is a rare developmental anomaly where the tooth buds fail to form.

This code is appropriate when a patient presents with a complete lack of teeth due to a congenital defect. Documentation should clearly state "anodontia" or describe the complete absence of dentition from birth.

• Differentiate from edentulism (loss of teeth after development) which is coded differently.
• Ensure documentation specifies the congenital nature of the absence.
• Consider co-occurring congenital anomalies, as anodontia can be part of broader syndromes.
