ICD-10 Code K08.129 – Complete loss of teeth due to periodontal diseases, unspecified class (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K08.129 – Complete loss of teeth due to periodontal diseases, unspecified class
What it is
This code identifies total tooth loss caused by periodontal disease, with the class of edentulism not specified. Use it when the record shows all teeth are gone because of periodontal destruction, but no class detail is documented.
Clinical signs
Clinical notes may describe complete edentulism, a history of advanced periodontal disease, or loss of all natural teeth after periodontal breakdown. Clinical features vary; refer to documentation.
When to use this code
Use K08.129 when the provider documents complete loss of teeth due to periodontal disease and does not assign a specific class. It fits dental or medical records that link the tooth loss to periodontal causes rather than trauma, caries, or congenital absence. Check documentation if the cause is unclear.
Do not use for
Do not use this code for partial tooth loss, unspecified edentulism, or tooth loss from nonperiodontal causes. If the record does not clearly state periodontal disease as the cause, use another code or check documentation.
Coding tip
Confirm both the complete tooth loss and the periodontal cause before assigning K08.129.
