ICD-10 Code K08.49 – Partial loss of teeth due to other specified cause (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K08.49 – Partial loss of teeth due to other specified cause
What it is
K08.49 identifies partial loss of teeth when the cause is documented as another specified reason not captured by a more specific dental code. Use it for tooth loss that is partial, not complete, and clearly attributed in the record.
Clinical signs
You may see missing teeth with remaining natural teeth present, altered chewing, or reduced dental arch integrity. Clinical features vary; refer to documentation for the stated cause and extent of tooth loss.
When to use this code
Use this code when the provider documents partial tooth loss and names a specific nonstandard cause, such as trauma-related loss or another stated condition, without a better-matching code. It is appropriate when the chart distinguishes partial loss from complete edentulism. Check documentation if the cause is vague or unspecified.
Do not use for
Do not use this code for complete loss of teeth, congenital absence, or cases where another more specific ICD-10 code describes the cause. If the record only says “tooth loss” without partial extent or cause, check documentation.
Coding tip
Confirm both the partial extent and the documented cause before assigning K08.49.
