Retained tooth

This code indicates the presence of a tooth that has not erupted into its normal functional position within the dental arch at the expected time. This can include impacted teeth, unerupted teeth, or teeth that are partially erupted but remain embedded in the jawbone or soft tissue.

Use this code when documenting a patient's diagnosis of a tooth that is retained, whether it is fully impacted, partially impacted, or simply unerupted. This applies to both primary and permanent dentition. It is often used in conjunction with codes specifying the specific tooth involved.

• Always code the specific tooth involved using an additional code from categories K00-K14 (Diseases of oral cavity and salivary glands) if known.
• Distinguish between retained teeth and supernumerary teeth; supernumerary teeth have a different coding pathway.
• Consider if there are any associated complications (e.g., cyst formation, infection) that also need to be coded.
