CPT® Code 61559

Extensive craniectomy for multiple cranial suture craniosynostosis (eg, cloverleaf skull); recontouring with multiple osteotomies and bone autografts (eg, barrel-stave procedure) (includes obtaining grafts)

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 early closure of these sutures restricts the normal growth of the skull, resulting in increased intracranial pressure and potential impairment of brain development. This condition can manifest as abnormalities in the shape of the head, often requiring surgical intervention to correct. Craniosynostosis can occur in isolation or as part of various syndromes, including Crouzon, Apert, Carpenter, Chotzen, or Pfeiffer syndrome, which may present with additional physical anomalies. The classification of craniosynostosis is divided into simple, where only a single suture is affected, and complex, where multiple sutures are involved. The surgical procedure described by CPT® Code 61559 involves an extensive craniectomy, which is a significant surgical intervention aimed at correcting the deformities associated with multiple cranial suture craniosynostosis. This procedure includes the recontouring of the skull through multiple osteotomies and the use of bone autografts, such as in the barrel-stave technique, to achieve optimal cosmetic and functional outcomes. The process also encompasses the harvesting of grafts, which are essential for reshaping the skull and ensuring proper healing and structural integrity post-surgery.
