ICD-10 Code K08.81 – Primary occlusal trauma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K08.81 – Primary occlusal trauma
What it is
Primary occlusal trauma means injury to the supporting tissues of a tooth caused by excessive biting forces on a tooth with normal periodontal support. Use this code when the problem is due to force, not periodontal disease.
Clinical signs
Common findings include tooth mobility, discomfort on chewing, and tenderness to percussion. Clinical features vary; refer to documentation.
When to use this code
Use K08.81 when the record documents trauma from occlusion affecting a tooth without loss of attachment or other periodontal destruction. It may be used for cases involving high restorations, bruxism-related force, or other documented excessive bite pressure. Check documentation if the cause is unclear.
Do not use for
Do not use this code for periodontal disease with secondary occlusal trauma or for general tooth pain without documented occlusal injury. Do not apply it when the chart does not support primary force-related trauma.
Coding tip
Code only when the provider clearly links symptoms to excessive occlusal force and normal periodontal support.
