ICD-10 Code K08.101 – Complete loss of teeth, unspecified cause, class I (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K08.101 – Complete loss of teeth, unspecified cause, class I
What it is
K08.101 identifies complete loss of teeth in a patient, with no specified cause and classified as class I. Use it when the record documents total tooth loss and the provider assigns this class.
Clinical signs
Findings typically include absence of all natural teeth in the affected arch or mouth, with corresponding edentulous appearance. Clinical features vary; refer to documentation.
When to use this code
Use this code when the chart clearly states complete loss of teeth, unspecified cause, class I. It is appropriate for dental or medical records that document full edentulism without naming trauma, disease, or another cause. Check documentation if the cause or class is unclear.
Do not use for
Do not use it for partial tooth loss, retained roots, or tooth absence with a documented specific cause that is coded elsewhere. Do not assume class I if the record does not support it.
Coding tip
Verify both the “complete loss” wording and the class designation before assigning K08.101.
