ICD-10 Code K08.499 – Partial loss of teeth due to other specified cause, unspecified class (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K08.499 – Partial loss of teeth due to other specified cause, unspecified class
What it is
This code identifies partial tooth loss caused by a documented reason other than the common listed causes, when the affected dental class is not specified. Use it for partial edentulism with an “other specified” etiology.
Clinical signs
Clinical features vary; refer to documentation. You may see missing teeth, reduced chewing function, or visible gaps in the dentition, but the record must support the specified nonstandard cause and partial loss.
When to use this code
Use K08.499 when the chart states partial loss of teeth from a specific cause not captured by a more exact code, and the class is not identified. It is appropriate when the provider documents partial tooth loss with an “other specified” cause. Check documentation if the cause is vague or the class is named elsewhere.
Do not use for
Do not use this code for complete tooth loss, congenital absence of teeth, or routine dental caries without documented partial loss. If the cause is unspecified or a more specific code applies, select that code instead.
Coding tip
Confirm both the partial loss and the exact documented cause before assigning K08.499.
