ICD-10 Code K08.8 – Other specified disorders of teeth and supporting structures (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K08.8 – Other specified disorders of teeth and supporting structures
What it is
K08.8 identifies a specified disorder affecting the teeth or their supporting structures that does not fit a more exact ICD-10-CM category. Use it when the record names a particular dental or periodontal problem, but no better code applies.
Clinical signs
Clinical features vary; refer to documentation. Findings may include tooth damage, structural abnormalities, or problems involving adjacent supporting tissues when the provider documents a specific disorder.
When to use this code
Use K08.8 when the clinician documents a named disorder of the teeth or supporting structures and you cannot map it to a more specific code. It may apply to unusual or residual conditions, provided the note supports the diagnosis. Check documentation if the record is vague.
Do not use for
Do not use this code for routine dental caries, periodontal disease, or tooth loss that has a more specific ICD-10-CM code. If the chart only says “dental problem” without detail, check documentation.
Coding tip
Code the most specific documented dental diagnosis first; use K08.8 only when no other ICD-10-CM option fits.
