Summary & Overview
CPT 63700: Repair of Meningocele (meningeal sac under 5 cm)
CPT code 63700 denotes the surgical repair of a meningocele, a congenital defect in which the meninges protrude through a skull or spinal column defect forming a sac under 5 cm in diameter. Nationally, this code captures a niche but clinically significant neurosurgical procedure used to protect neural tissue and prevent infection or neurologic compromise. Use of this code influences facility and physician billing, coverage review, and payment policy for congenital cranial and spinal repairs.
Key payers referenced include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Coverage and payment practices for 63700 vary across commercial and government plans, with differences in site-of-service determinations, prior authorization requirements, and bundled payment considerations for pediatric and adult surgical care.
Readers will find a concise clinical context for the procedure, an overview of common payer coverage patterns, and guidance on the types of benchmarks and policy updates to monitor—such as changes to surgical bundling, inpatient versus outpatient designation, and coding guidance tied to defect size and concurrent procedures. Data not available in the input is noted where applicable, and the publication does not provide clinical recommendations but frames the code’s relevance for billing, coverage, and administrative policy.
Billing Code Overview
CPT code 63700 describes surgical repair of a meningocele—a congenital defect in which the meninges protrude through a defect in the skull or spinal column, forming a cerebrospinal fluid–filled sac less than 5 cm in diameter. The procedure involves closure and reconstruction of the meningeal sac and surrounding tissues to protect neural structures and restore normal anatomy.
Service type: Surgical repair of congenital meningeal sac (meningocele repair)
Typical site of service: Inpatient or outpatient surgical setting, commonly performed in an operating room in hospitals or ambulatory surgical centers depending on clinical factors and patient age.
Clinical & Coding Specifications
Clinical Context
A newborn infant presents with a visible midline sac along the spinal column consistent with a meningocele. Prenatal ultrasound raised concern for neural tube defect; delivery occurred at a tertiary care center with pediatric neurosurgery available. Initial evaluation includes focused neurological exam, wound assessment to rule out CSF leakage or sac rupture, and imaging (spinal ultrasound or MRI) to define the sac size and adjacent spinal elements. For a meningocele with a sac diameter under 5 cm, the pediatric neurosurgeon schedules surgical closure under general anesthesia in the operating room. The clinical workflow includes preoperative clearance (neonatology, anesthesia), perioperative antibiotics, positioning and sterile preparation, careful dissection of the meningeal sac from surrounding skin and soft tissue, watertight dural repair, reconstruction of the fascia and multilayer soft tissue closure, and skin closure. Postoperative care involves monitoring for signs of infection, CSF leak, wound breakdown, and hydrocephalus, with neurosurgical follow-up and possible postoperative imaging. This procedure is typically billed when the defect is limited to the meninges without significant neural tissue herniation and the sac measures less than 5 cm in diameter.
