Cloverleaf skull

This code represents a severe congenital malformation of the skull characterized by a trilobular or "cloverleaf" appearance. This distinctive shape results from premature closure of multiple cranial sutures (craniosynostosis), leading to an abnormal expansion of the brain in specific areas. It is often associated with other skeletal dysplasias and genetic syndromes.

Use this code when documentation explicitly states "cloverleaf skull" or "Kleeblattschädel anomaly." This diagnosis is typically made prenatally via ultrasound or at birth based on physical examination and confirmed with imaging studies like CT scans. The presence of severe craniosynostosis with the characteristic skull shape supports its use.

• Ensure documentation clearly specifies "cloverleaf skull" rather than general craniosynostosis, as this is a distinct and severe form.
• Code any associated genetic syndromes or other congenital anomalies separately.
• Consider sequencing this code as the primary diagnosis when it is the main reason for the encounter or admission.
