ICD-10 Code K08.10 – Complete loss of teeth, unspecified cause (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K08.10 – Complete loss of teeth, unspecified cause
What it is
K08.10 identifies complete loss of teeth when the cause is not specified in the record. Use it for total edentulism without documentation of trauma, periodontal disease, or another defined etiology.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include absence of all natural teeth, with or without dentures, and a charted diagnosis of complete tooth loss rather than partial loss.
When to use this code
Use this code when the provider documents complete loss of teeth and does not state the cause. It fits encounters focused on edentulism, denture assessment, or oral exam findings where the record lacks a more specific etiology. If a cause is documented, code that condition instead.
Do not use for
Do not use K08.10 for partial tooth loss, retained roots, or tooth loss with a documented cause such as trauma or periodontal disease. Check documentation if the record specifies a different oral condition.
Coding tip
Code K08.10 only when the chart clearly supports complete tooth loss and no cause is stated.
