Summary & Overview
CPT 49605: Repair of Large Omphalocele or Gastroschisis
CPT code 49605 denotes repair of a large omphalocele or gastroschisis, congenital defects of the abdominal wall that commonly require specialized surgical closure and possible use of prosthetic material. This code captures a high-acuity operative service, typically performed by pediatric or general surgeons in inpatient surgical settings and, in select cases, in ambulatory surgical centers. Nationally, management of these complex neonatal and pediatric conditions has implications for hospital resource use, perioperative planning, and networks of specialized surgical care.
Key payers examined include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication provides a concise overview of how CPT code 49605 is used in clinical practice, common sites of service, and payer considerations relevant to coverage and billing workflows. Readers will find benchmarks for utilization and reimbursement (where available), summaries of relevant policy themes, and clinical context that explains why accurate coding is important for care coordination, claims processing, and quality measurement.
The report is intended for billing professionals, hospital revenue leaders, surgical department administrators, and policy analysts seeking a focused reference on coding, site-of-service considerations, and payer engagement for repair of large omphaloceles or gastroschisis.
Billing Code Overview
CPT code 49605 describes surgical repair of a large omphalocele or gastroschisis, congenital abdominal wall defects. The procedure may be performed with or without use of a prosthetic material. This service involves operative closure and reconstruction of the abdominal wall and associated tissues.
Service type: Surgical procedure (pediatric/general surgery)
Typical site of service: Inpatient hospital operating room or ambulatory surgical center depending on patient condition and institutional practice.
Clinical & Coding Specifications
Clinical Context
A neonate is born with a large ventral abdominal wall defect consistent with a giant omphalocele or complex gastroschisis, requiring definitive surgical repair. The infant is stabilized in the neonatal intensive care unit with thermoregulation, intravenous fluids, parenteral nutrition, and protection of exposed viscera with sterile silo or dressings. Preoperative evaluation includes neonatal surgical consultation, anesthesiology assessment, imaging (abdominal ultrasound or radiographs), and laboratory studies. The operating surgeon performs reduction of herniated abdominal contents, assesses viability of bowel, closes the abdominal wall defect with primary fascial closure when feasible, or uses prosthetic material (prosthesis) such as a silo or mesh if primary closure would cause abdominal compartment syndrome. Intraoperative steps include exploration, reduction of viscera, resection of nonviable segments if present, and layered fascial and skin closure. Postoperative care occurs in the NICU with ventilatory support as needed, pain management, monitoring for infection, and gradual advancement of enteral feeds. Possible staged repairs may be required for very large defects, with return trips to the operating room for staged fascial closure and/or prosthesis removal.
