ICD-10 Code K08.1 – Complete loss of teeth (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K08.1 – Complete loss of teeth
What it is
K08.1 identifies complete loss of teeth, meaning all natural teeth are absent. Use it when the record clearly documents total tooth loss, whether from disease, extraction, trauma, or other causes.
Clinical signs
Typical findings include a fully edentulous mouth and inability to identify any remaining natural teeth. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents complete tooth loss on examination, in a dental history, or in a problem list. It may also fit when a patient is described as edentulous or having no remaining natural teeth. Check documentation if the chart does not clearly state whether loss is complete.
Do not use for
Do not use K08.1 for partial tooth loss, missing individual teeth, or removable dentures alone. If the note is unclear, check documentation before assigning a code.
Coding tip
Code only when the record confirms total absence of natural teeth, not just dental prosthesis use.
