Lambdoid craniosynostosis, bilateral

This code signifies the premature fusion of both lambdoid sutures of the skull, a congenital anomaly that restricts normal skull growth. This bilateral fusion leads to a characteristic skull deformity, often presenting as a flattened occiput and potential compensatory bulging in other areas.

Apply this code for patients diagnosed with bilateral lambdoid craniosynostosis, typically identified in infancy or early childhood. Documentation should clearly specify the involvement of both lambdoid sutures, often confirmed by imaging studies such as CT scans.

• Ensure documentation explicitly states "bilateral" involvement of the lambdoid sutures to support this specific code.
• Distinguish from unilateral lambdoid craniosynostosis (Q75.041) and other types of craniosynostosis.
• Consider coding any associated neurological complications or developmental delays separately, if documented.
