ICD-10 Code K08.13 – Complete loss of teeth due to caries (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K08.13 – Complete loss of teeth due to caries
What it is
K08.13 identifies complete tooth loss caused by dental caries. Use it when documentation shows all teeth are absent because decay led to their loss, not because of trauma or congenital absence.
Clinical signs
Patients typically have no remaining natural teeth and a history of extensive decay or carious destruction. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly states complete loss of teeth due to caries, including edentulism from untreated or advanced decay. Code it from dental, oral surgery, or medical documentation that links the tooth loss to caries. Check documentation if the cause is unclear.
Do not use for
Do not use it for tooth loss from trauma, periodontal disease, congenital absence, or extraction without documented caries as the cause. If the chart does not specify etiology, check documentation.
Coding tip
Assign K08.13 only when the provider documents caries as the reason for complete tooth loss.
