ICD-10 Code K08.3 – Retained dental root (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K08.3 – Retained dental root
What it is
K08.3 identifies a retained root fragment left in the jaw after part of a tooth has broken off or been removed. Use it when the record specifically documents a retained dental root.
Clinical signs
Findings may include a visible or radiographic root remnant, localized dental pain, or irritation of surrounding tissues. Clinical features vary; refer to documentation.
When to use this code
Use K08.3 when the dentist or clinician documents a retained root, such as a root left after extraction or a fractured tooth with remaining root structure. Code it when the retained root is the reason for evaluation, treatment, or follow-up. Check documentation if the note only says “broken tooth” without confirming retained root.
Do not use for
Do not use this code for a fully erupted tooth, simple toothache, or general dental caries without retained root documentation. If the record describes another dental disorder, choose the more specific diagnosis.
Coding tip
Confirm that the provider explicitly documents a retained root fragment before assigning K08.3.
