CPT® Code 61556

Craniosynostosis is a congenital condition characterized by the premature fusion of one or more cranial sutures in infants, which can lead to significant complications. The cranial sutures are fibrous joints that connect the bones of the skull, allowing for growth and development of the brain during infancy. When these sutures close too early, it restricts the normal expansion of the skull, resulting in increased intracranial pressure and potential impairment of brain development. Additionally, the abnormal closure can lead to distinctive head shapes, which may vary depending on which sutures are involved. Craniosynostosis can occur in isolation or as part of syndromic conditions such as Crouzon, Apert, Carpenter, Chotzen, or Pfeiffer syndrome, which may present with other physical abnormalities. The condition is categorized into simple craniosynostosis, where only one suture is affected, and complex craniosynostosis, where multiple sutures are involved. The procedure described by CPT® Code 61556 involves a craniotomy specifically for the treatment of craniosynostosis, focusing on the frontal or parietal bone flap. This surgical intervention aims to relieve pressure on the brain and facilitate normal skull growth by creating a bone flap that can be repositioned as necessary.
