ICD-10 Code K08.133 – Complete loss of teeth due to caries, class III (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K08.133 – Complete loss of teeth due to caries, class III
What it is
K08.133 identifies complete tooth loss caused by dental caries, with class III severity. Use it when the record clearly documents total loss of teeth from decay rather than trauma, periodontal disease, or congenital absence.
Clinical signs
Documentation usually shows edentulism with a history of severe caries as the cause. Clinical features vary; refer to documentation for the class III designation and whether the loss is complete.
When to use this code
Use this code when the provider states the patient has complete loss of teeth due to caries and specifies class III. It fits dental or medical records that link the tooth loss directly to decay. If the cause or class is not documented, check documentation before assigning the code.
Do not use for
Do not use it for tooth loss from periodontal disease, trauma, congenital absence, or partial loss of teeth. If the record does not confirm caries as the cause, select a different code.
Coding tip
Assign K08.133 only when both the cause and the class are explicitly documented.
