CPT® Code 63706

A myelomeningocele is a severe form of spina bifida, which is a congenital defect resulting from improper closure of the neural tube during early fetal development. This condition is characterized by the protrusion of both the spinal cord and the protective membranes (meninges) through an opening in the spine, creating a sac-like structure. In cases of myelomeningocele, the defect is typically larger than 5 cm in diameter, necessitating surgical intervention to repair the defect. The procedure involves making an incision in the membrane covering the spinal cord and meninges, allowing for the drainage of any excess cerebrospinal fluid. Following this, the dura mater, which is the tough outer layer of the meninges, is sutured closed over the spinal cord to protect it. The skin is then meticulously closed in layers over the area, ensuring that the protruding meninges, spinal cord, and nerves are adequately covered. In instances where direct closure of the defect is not feasible, a skin flap may be created from adjacent skin on the back or buttocks. This flap is then rotated to cover the defect and secured in place with sutures. It is important to note that CPT® Code 63706 is specifically designated for repairs of myelomeningocele that are 5 cm or larger, while CPT® Code 63704 is used for defects smaller than this size.
