ICD-10 Code K08.4 – Partial loss of teeth (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K08.4 – Partial loss of teeth
What it is
K08.4 identifies partial loss of teeth, meaning one or more natural teeth are missing but not all teeth are absent. Use it when the record documents tooth loss without a more specific cause.
Clinical signs
Findings usually include missing teeth on exam, altered chewing, or visible gaps in the dentition. Clinical features vary; refer to documentation.
When to use this code
Use K08.4 when the provider documents partial tooth loss, edentulism limited to some teeth, or similar wording. It fits dental or medical notes that describe missing teeth without specifying trauma, congenital absence, or another defined condition. If the cause is documented, code that condition instead when appropriate.
Do not use for
Do not use this code for complete tooth loss or for teeth missing due to a clearly documented congenital anomaly. Check documentation if the record describes extraction, trauma, or another underlying diagnosis.
Coding tip
Code the documented tooth loss itself, and look for a stated cause before assigning K08.4.
