ICD-10 Code K08 – Other disorders of teeth and supporting structures (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K08 – Other disorders of teeth and supporting structures
What it is
K08 covers dental and periodontal conditions affecting the teeth and their supporting tissues that are not classified elsewhere. Use it for documented disorders of the teeth, gums, or supporting structures when no more specific code fits.
Clinical signs
Clinical features vary; refer to documentation. Findings may include tooth loss, abnormal tooth development, or other structural problems involving teeth or supporting tissues noted on exam or imaging.
When to use this code
Use K08 when the provider documents a nonspecific disorder of the teeth or supporting structures and a more precise diagnosis is not available. It is appropriate for charted dental abnormalities, missing teeth, or other structural conditions not otherwise classified. Check documentation if the record does not clearly specify the disorder.
Do not use for
Do not use K08 when a more specific dental, periodontal, or jaw diagnosis is documented. Avoid it for routine dental caries, gingival disease, or trauma-related tooth injury unless the record supports this code.
Coding tip
Look for the exact provider wording and code the most specific dental diagnosis first; use K08 only when no better-defined option is documented.
