ICD-10 Code K08.191 – Complete loss of teeth due to other specified cause, class I (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K08.191 – Complete loss of teeth due to other specified cause, class I
What it is
K08.191 identifies complete loss of teeth caused by an other specified cause, class I. Use it when the record documents total tooth loss and the cause fits this category rather than routine age-related loss.
Clinical signs
Clinical features vary; refer to documentation. You may see a fully edentulous mouth, absent natural teeth, and notes describing the specific nontraumatic cause that led to the loss.
When to use this code
Use this code when the provider documents complete tooth loss and identifies an other specified cause, class I. It is appropriate for coding a finalized diagnosis in the chart, dental evaluation, or referral note. Check documentation if the cause is unclear or not classified here.
Do not use for
Do not use it for partial tooth loss, unspecified edentulism, or tooth loss from a different documented cause. If the record supports another ICD-10 category, code that instead.
Coding tip
Verify both the completeness of tooth loss and the exact documented cause before assigning K08.191.
