ICD-10 Code K08.493 – Partial loss of teeth due to other specified cause, class III (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K08.493 – Partial loss of teeth due to other specified cause, class III
What it is
This code describes partial loss of teeth caused by a specified nontraumatic cause, documented as class III. Use it when the record identifies this exact category rather than a general tooth-loss diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Findings usually include missing teeth or reduced dentition, with the cause noted in the chart as something other than trauma, caries, or periodontal disease.
When to use this code
Use K08.493 when the provider documents partial tooth loss from another specified cause and includes class III. This may appear in dental or medical records where the etiology is clearly stated. If the cause or class is not documented, check documentation before coding.
Do not use for
Do not use this code for complete tooth loss, traumatic tooth loss, or tooth loss due to caries or periodontal disease. If the record does not support the specified cause or class III, choose a more accurate code.
Coding tip
Verify both the documented cause and the class designation before assigning K08.493.
