ICD-10 Code K08.492 – Partial loss of teeth due to other specified cause, class II (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K08.492 – Partial loss of teeth due to other specified cause, class II
What it is
K08.492 identifies partial loss of teeth caused by a specified non-traumatic, non-dental condition, classified as class II. Use it when the record clearly documents this exact cause and severity.
Clinical signs
Typical findings include missing teeth with remaining dentition still present. Clinical features vary; refer to documentation for the stated cause and whether the loss is partial and class II.
When to use this code
Use this code when the provider documents partial tooth loss due to another specified cause and identifies it as class II. It may apply in dental or medical records when the cause is recorded but not better captured by trauma, caries, or periodontal disease. Check documentation if the etiology is unclear.
Do not use for
Do not use it for complete edentulism, tooth loss from trauma, or routine tooth extraction. If the cause is not specifically documented, check documentation before assigning this code.
Coding tip
Code only when the record states both partial tooth loss and the specified cause; otherwise, query the provider.
