Coronal craniosynostosis, bilateral

This code describes a congenital anomaly where both coronal sutures of the skull fuse prematurely. This bilateral fusion restricts normal skull growth, leading to a characteristic head shape often referred to as brachycephaly. It can impact brain development and may require surgical intervention.

Use this code for patients diagnosed with premature closure of both coronal sutures. Documentation should clearly specify "bilateral" involvement of the coronal sutures, typically confirmed by imaging studies such as CT scans. This code is appropriate for initial diagnosis and subsequent encounters related to the condition.

• Ensure documentation explicitly states "bilateral" coronal craniosynostosis; unilateral involvement uses a different code.
• Distinguish from other forms of craniosynostosis (e.g., sagittal, metopic) which have distinct codes.
• Code any associated malformations or complications, such as hydrocephalus or increased intracranial pressure, separately.
