CPT® Code 63700

A meningocele is a specific type of spina bifida, which is classified as a congenital anomaly resulting from improper closure of the neural tube during the early stages of fetal development, typically within the first month. In cases of meningocele, the spinal cord itself develops normally; however, there is a protrusion of the meninges, which are the protective membranes surrounding the spinal cord, through a defect in the vertebral column. This condition may present with a thin membrane covering the protruding meninges. The surgical procedure associated with CPT® Code 63700 involves the repair of a meningocele that is less than 5 cm in diameter. During the procedure, a surgical incision is made in the membrane (sac) that covers the meninges, allowing for the drainage of any excess cerebrospinal fluid that may be present. Following this, the skin is meticulously closed in layers over the protruding meninges to ensure proper healing and protection. In instances where direct closure of the skin is not feasible, a skin flap may be created from adjacent skin, typically from the back or buttocks. This flap is then rotated to adequately cover the defect and is sutured securely to the surrounding tissue. It is important to note that if the meningocele defect measures 5 cm or larger, CPT® Code 63702 should be utilized instead of 63700.
