ICD-10 Code K03.81 – Cracked tooth (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K03.81 – Cracked tooth
What it is
K03.81 identifies a cracked tooth, meaning a tooth has a fracture or visible crack that has not fully split the tooth. Use it when the record documents a crack rather than another dental defect.
Clinical signs
Patients may report pain when chewing, sensitivity to biting, or intermittent discomfort. Clinical features vary; refer to documentation, and confirm the crack is noted on exam, imaging, or dental assessment.
When to use this code
Use K03.81 when the clinician documents a cracked tooth as the diagnosis or reason for evaluation. It fits dental visits where the crack is the primary finding, even if symptoms are mild or intermittent.
If the note describes a fractured tooth with a different specific diagnosis, follow the documented condition. When the record is unclear about the tooth status, check documentation before assigning this code.
Do not use for
Do not use this code for generalized tooth decay, enamel defects, or routine tooth pain without a documented crack. If the chart instead states a broken, avulsed, or missing tooth, select the documented condition.
Coding tip
Code K03.81 only when the provider explicitly documents a cracked tooth; otherwise, query or check documentation.
