ICD-10 Code K08.139 – Complete loss of teeth due to caries, unspecified class (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K08.139 – Complete loss of teeth due to caries, unspecified class
What it is
K08.139 identifies complete tooth loss caused by dental caries when the record does not specify the class or pattern. Use it for edentulism attributed to decay, not to trauma or periodontal disease.
Clinical signs
Clinical features vary; refer to documentation. You may see a fully edentulous mouth with a history of severe decay, extraction after caries, or notes stating teeth were lost because of carious destruction.
When to use this code
Use this code when the provider documents complete loss of teeth due to caries and does not identify a class. It fits charted cases where decay is the stated cause of total tooth loss, including post-extraction records that link the loss to caries.
If the note only says “edentulous” or “missing teeth,” you need a documented cause before assigning K08.139. Check documentation when the etiology is unclear or when another condition better explains the tooth loss.
Do not use for
Do not use this code for partial tooth loss, congenital absence of teeth, or tooth loss from trauma, periodontal disease, or surgery unless caries is specifically documented. Check documentation.
Coding tip
Confirm that the provider explicitly links complete tooth loss to caries and that no more specific class is documented before assigning K08.139.
