CPT® Code 61557

Craniosynostosis is a congenital condition characterized by the premature fusion of one or more cranial sutures in infants, which can lead to significant complications. This early closure restricts the normal growth of the skull, resulting in increased intracranial pressure that can adversely affect brain development. Additionally, it can cause noticeable deformities in the shape of the head. The condition may present as an isolated issue or as part of a broader syndrome, such as Crouzon, Apert, Carpenter, Chotzen, or Pfeiffer syndrome, which are associated with various other physical abnormalities. Craniosynostosis is categorized into two types: simple, where only a single suture is involved, and complex, where multiple sutures are fused. The procedure described by CPT® Code 61557 involves a craniotomy specifically for craniosynostosis, utilizing a bifrontal bone flap. This surgical intervention aims to correct the abnormal skull shape and alleviate pressure on the brain, thereby facilitating normal brain growth and development. The technique involves creating a bone flap from the frontal bone, which is then elevated to allow access to the underlying structures, ensuring that the skull can be reshaped appropriately to support healthy cranial development.
