CPT® Code 49605

The CPT® Code 49605 refers to the surgical procedure for the repair of a large omphalocele or gastroschisis, which are congenital defects involving the abdominal wall. An omphalocele is characterized by a large umbilical ring defect where internal organs, including the bowel, are located outside the abdomen, covered by a thin membrane. In contrast, gastroschisis involves a defect located to the side of the umbilicus, where the bowel and other organs protrude without a protective membrane. This procedure is critical for restoring the integrity of the abdominal wall and ensuring that the internal organs are properly positioned within the abdominal cavity. The physician may employ one of two primary techniques during the repair. The first technique involves directly closing the defect without the use of a prosthesis, utilizing manual manipulation to stretch the abdominal wall and accommodate the internal organs. The second technique involves the use of a prosthetic silo or pouch, which allows for a gradual reduction of the herniated organs into the abdomen over time. This procedure is essential for preventing complications associated with these congenital defects and facilitating normal abdominal function and development in affected infants.
