ICD-10 Code K08.104 – Complete loss of teeth, unspecified cause, class IV (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K08.104 – Complete loss of teeth, unspecified cause, class IV
What it is
K08.104 identifies complete loss of teeth when the cause is not specified and the condition is classified as class IV. Use it for documented total tooth loss that matches this class designation.
Clinical signs
Clinical features include absence of all natural teeth in the affected dentition. Clinical features vary; refer to documentation for the class IV designation and any recorded cause.
When to use this code
Use this code when the record states complete loss of teeth, unspecified cause, and specifically identifies class IV. It fits dental or medical documentation showing total edentulism without a stated etiology. If the cause is known or a different class is documented, check documentation.
Do not use for
Do not use it for partial tooth loss, retained teeth, or loss with a documented specific cause that should be coded elsewhere. Do not guess the class level if the chart does not support class IV.
Coding tip
Verify that both the unspecified cause and class IV are explicitly documented before assigning K08.104.
