Hereditary disturbances in tooth structure, not elsewhere classified

This code signifies inherited conditions affecting the development and integrity of tooth structure, excluding those specifically classified elsewhere. It encompasses genetic disorders that lead to abnormalities in enamel, dentin, or cementum, resulting in teeth that are often discolored, malformed, or prone to fracture.

Apply this code for diagnoses such as amelogenesis imperfecta, dentinogenesis imperfecta, or regional odontodysplasia when the hereditary nature is confirmed and a more specific ICD-9 code is unavailable. Documentation should clearly state the genetic basis or familial history of the tooth structure disturbance.

• Do not use for acquired tooth structure defects or developmental anomalies without a clear hereditary component.
• Consider additional codes for associated clinical manifestations, such as malocclusion or pulp pathology.
• Ensure documentation specifies the hereditary nature to differentiate from other developmental disturbances of teeth.
