ICD-10 Code K08.89 – Other specified disorders of teeth and supporting structures (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K08.89 – Other specified disorders of teeth and supporting structures
What it is
K08.89 identifies a dental or periodontal condition affecting teeth or supporting structures that does not fit a more specific ICD-10-CM code. Use it when the chart documents a named disorder, but no better code is available.
Clinical signs
Clinical features vary; refer to documentation. Findings may include tooth-related pain, structural damage, or changes in the supporting tissues, but the record should specify the exact disorder when possible.
When to use this code
Use this code when the provider documents an unspecified but clearly described disorder of the teeth or supporting structures, and no more specific diagnosis is supported. It can apply to unusual or residual dental conditions that are not classified elsewhere. Check documentation if the note is vague.
Do not use for
Do not use K08.89 for routine caries, gingival disease, or traumatic dental injuries that have their own codes. If the condition is better described by another dental or oral diagnosis, code that instead.
Coding tip
Look for the most specific dental diagnosis first; K08.89 is a fallback code when the documentation names a disorder but offers no exact match.
