Pathological resorption of teeth

This code signifies the abnormal breakdown and loss of tooth structure due to non-physiological processes, distinct from dental caries or trauma. It encompasses various forms of internal or external resorption that lead to the destruction of dentin, cementum, or bone surrounding the tooth.

Apply this code when documentation specifies conditions like internal inflammatory resorption, external cervical resorption, or replacement resorption. It is appropriate for cases where the tooth structure is being resorbed due to an underlying pathological process, often identified radiographically or clinically.

• Differentiate from dental caries (K02.-) or tooth wear (K03.0-K03.2), which are distinct processes of tooth destruction.
• Specify the type of resorption if documented (e.g., internal, external, cervical) for potential future sub-classification.
• Ensure the documentation clearly indicates a pathological cause, not just normal physiological root resorption in deciduous teeth.
