Other specified disorders of tooth development and eruption

This code encompasses various uncommon or atypical conditions affecting the formation and emergence of teeth that are not classified elsewhere. It covers developmental anomalies beyond simple agenesis or impaction, such as unusual tooth morphology, size, or structural defects.

This code is appropriate for documenting conditions like gemination, fusion, concrescence, dens invaginatus (dens in dente), or supernumerary roots when a more specific code is unavailable. Documentation should clearly describe the specific developmental or eruptive anomaly observed.

• Avoid using this code if a more specific ICD-9-CM code exists for the documented condition (e.g., 520.0 for anodontia).
• Ensure the medical record explicitly details the "other specified" disorder to justify its use.
• Consider sequencing this code as a secondary diagnosis if the primary reason for the encounter is a complication arising from the developmental anomaly.
