ICD-10 Code K03.6 – Deposits [accretions] on teeth (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K03.6 – Deposits [accretions] on teeth
What it is
K03.6 identifies deposits or accretions on the teeth, such as visible buildup on tooth surfaces. It is used when the record documents dental deposits rather than decay or gum disease.
Clinical signs
Findings may include plaque, tartar, or other adherent material on the teeth. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents deposits on teeth as the reason for the visit or as an exam finding. It may apply during routine dental assessment, cleaning, or evaluation of oral hygiene. Code it only when the chart clearly describes tooth accretions.
Do not use for
Do not use K03.6 for dental caries, gingivitis, or generalized oral disease unless deposits on teeth are specifically documented. Check documentation if the note only mentions plaque without a diagnosis.
Coding tip
Look for explicit wording such as “deposits,” “accretions,” or “tartar” before assigning K03.6.
