Other specified diseases of hard tissues of teeth

This code signifies various non-carious, non-developmental, and non-traumatic conditions affecting the hard tissues of teeth that are not classified elsewhere. It encompasses a range of acquired dental hard tissue disorders beyond common caries, attrition, abrasion, erosion, or dentin hypersensitivity.

Use this code for documented conditions such as internal or external resorption of teeth, pulp stones, or hypercementosis, when these conditions are not due to trauma or developmental anomalies. Documentation should clearly specify the particular hard tissue disease affecting the tooth.

• Ensure documentation explicitly states the specific "other specified" condition, as this is a residual code.
• Avoid using this code for conditions with more specific ICD-10-CM codes, such as dental caries (K02.-) or attrition (K03.0).
• If the condition is secondary to another disease process, consider sequencing the underlying disease first, if applicable.
