ICD-10 Code K08.103 – Complete loss of teeth, unspecified cause, class III (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K08.103 – Complete loss of teeth, unspecified cause, class III
What it is
K08.103 identifies complete loss of teeth when the cause is not specified and the condition is class III. Use it when the record documents full tooth loss and the classification level is clearly stated.
Clinical signs
Clinical features include absence of all natural teeth in the mouth. Documentation may note edentulism, use of dentures, or a dental exam confirming complete tooth loss; clinical features vary, refer to documentation.
When to use this code
Use this code when the provider documents complete tooth loss, the cause is not identified, and class III is recorded. It is appropriate for dental, oral surgery, or general medical notes that clearly support the classification. If the chart does not specify class III, check documentation.
Do not use for
Do not use it for partial tooth loss, retained roots, or tooth loss with a documented specific cause that should be coded instead. If the record does not confirm complete loss of teeth, check documentation.
Coding tip
Code only when both complete edentulism and class III are explicitly documented.
