ICD-10 Code K08.131 – Complete loss of teeth due to caries, class I (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K08.131 – Complete loss of teeth due to caries, class I
What it is
K08.131 identifies complete tooth loss caused by dental caries, limited to class I. Use it when documentation states all teeth are missing because of decay, with the class I designation recorded.
Clinical signs
Clinical features vary; refer to documentation. You may see edentulism with a history of advanced caries, but the record should specifically link the tooth loss to decay and note class I.
When to use this code
Use this code when the provider documents complete loss of teeth due to caries and specifically identifies class I. It fits charted dental diagnoses, prosthodontic evaluations, or problem lists that match this wording. If the cause or class is unclear, check documentation.
Do not use for
Do not use it for missing teeth from trauma, periodontal disease, congenital absence, or unspecified tooth loss. If the record does not clearly state caries as the cause, this code is not appropriate.
Coding tip
Code only when both the cause and class are documented; otherwise, query for clarification.
