ICD-10 Code A50.52 – Hutchinson’s teeth (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A50.52 – Hutchinson’s teeth
What it is
Hutchinson’s teeth are a classic dental finding associated with congenital syphilis. The teeth are typically notched, peg-shaped, or otherwise malformed, especially the permanent incisors.
Clinical signs
Look for characteristic central incisors with a small, crescent-shaped notch and abnormal tooth shape. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record specifically documents Hutchinson’s teeth as a diagnosis or notable finding. It may appear in patients with a history of congenital syphilis or when dental examination identifies the classic tooth deformity. Check documentation if the note only mentions dental caries or unspecified enamel defects.
Do not use for
Do not use it for general tooth discoloration, routine malocclusion, or unspecified congenital dental anomalies. If the chart does not clearly identify Hutchinson’s teeth, check documentation.
Coding tip
Code only when the provider explicitly documents Hutchinson’s teeth, not merely suspected syphilis-related dental changes.
