CPT® Code 49585

Deleted

An umbilical hernia repair for patients aged 5 years or older involves the surgical correction of a protrusion at the umbilicus, where abdominal contents such as omentum and bowel push through the abdominal wall. This procedure, coded as CPT® 49585, specifically addresses reducible hernias, meaning that the contents of the hernia sac can be manually pushed back into their normal anatomical position. The surgical approach typically begins with a curved incision made below the umbilicus, allowing access to the underlying tissues. The skin is carefully lifted away from the subcutaneous fat to expose the fascial edge of the hernia defect and the neck of the hernia sac. The anterior rectus muscle sheath is also exposed during this process. The surgical team then incises the neck of the hernia sac, detaching it from the abdominal wall, and extracts the hernia contents for inspection. If any adhesions are present, they are severed to ensure the bowel can be safely returned to the abdominal cavity. The omentum and hernia sac are excised, and the abdominal wall defect is closed, potentially using a mesh plug for larger defects. Finally, the skin is secured over the aponeurosis, and a pressure dressing may be applied to support the surgical site. It is important to note that if the hernia is found to be strangulated or incarcerated, a different code, CPT® 49587, should be used, as these conditions involve complications where the hernia contents cannot be repositioned or have compromised blood flow.
