ICD-10 Code K03.7 – Posteruptive color changes of dental hard tissues (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K03.7 – Posteruptive color changes of dental hard tissues
What it is
K03.7 identifies discoloration of dental hard tissues that develops after tooth eruption. Use it when the change in tooth color is the primary documented finding, rather than decay or another structural defect.
Clinical signs
Typical documentation notes visible staining, darkening, or other color alteration of enamel, dentin, or cementum after eruption. Clinical features vary; refer to documentation.
When to use this code
Use K03.7 when the record specifically describes post-eruptive tooth discoloration as the reason for evaluation or treatment. It may apply when the clinician documents staining from an acquired cause but does not identify caries, trauma, or another more specific diagnosis. Check documentation if the source of discoloration is unclear.
Do not use for
Do not use this code for congenital tooth discoloration, dental caries, or generalized oral pigmentation. If the discoloration is due to another documented dental disorder, code the more specific condition.
Coding tip
Code K03.7 only when the chart links the color change to the teeth themselves and not to surrounding oral tissues.
