ICD-10 Code K08.122 – Complete loss of teeth due to periodontal diseases, class II (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K08.122 – Complete loss of teeth due to periodontal diseases, class II
What it is
This code identifies complete loss of teeth caused by periodontal disease, with class II severity. Use it when the record clearly links total tooth loss to periodontal destruction rather than trauma or decay.
Clinical signs
Typical documentation may note edentulism with a history of periodontal disease, advanced attachment loss, or severe supporting tissue destruction. Clinical features vary; refer to documentation.
When to use this code
Use K08.122 when the provider documents complete tooth loss due to periodontal disease and specifies class II. It is appropriate for dental or medical records that describe the cause and severity. Confirm that the loss is not better explained by another condition.
Do not use for
Do not use this code for tooth loss from caries, trauma, congenital absence, or unspecified edentulism. Check documentation if the cause of loss is unclear.
Coding tip
Code only when periodontal disease is documented as the cause and class II is specifically stated.
