ICD-10 Code K08.494 – Partial loss of teeth due to other specified cause, class IV (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K08.494 – Partial loss of teeth due to other specified cause, class IV
What it is
This code identifies partial tooth loss caused by a documented reason other than the common listed causes. “Class IV” specifies the extent or severity category assigned in the record.
Clinical signs
Clinical features usually include missing teeth with an identified nonstandard cause, such as trauma or another specified condition. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly states partial loss of teeth and names an “other specified” cause. You should also confirm that the documentation assigns class IV, not another class. If the cause is not specified, check documentation before coding.
Do not use for
Do not use it for complete tooth loss or for partial loss due to a different coded cause. Avoid it when the chart does not support class IV or the documented cause belongs under another ICD-10 category.
Coding tip
Match both elements exactly: the cause and the class designation must appear in the documentation.
