CPT® Code 63702

A meningocele is a specific type of spina bifida, which is a congenital defect resulting from improper closure of the neural tube during early fetal development, typically within the first month. In cases of meningocele, the spinal cord develops normally; however, the protective membranes surrounding the spinal cord, known as the meninges, protrude through an opening in the spine. This protrusion can create a sac-like structure that may be covered by a thin membrane. The procedure coded as CPT® 63702 involves the surgical repair of a meningocele that is larger than 5 cm in diameter. During the repair, a surgical incision is made in the membrane covering 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 defect is not feasible, a skin flap may be created from adjacent skin, such as that from the back or buttocks. This flap is then rotated to adequately cover the defect and is sutured to the surrounding tissue to secure it in place. It is important to note that CPT® 63700 is used for repairs of meningocele defects that are less than 5 cm in diameter, while CPT® 63702 is specifically designated for those that are 5 cm or larger.
