CPT® Code 43870

The procedure described by CPT® Code 43870 refers to the surgical closure of a gastrostomy, which is a tube inserted through the abdominal wall into the stomach for feeding purposes. In this procedure, the gastrostomy tube is first removed, indicating that the need for enteral feeding through this route has ended. A small incision is made in the abdomen, specifically near the previous site of the gastrostomy, allowing access to the stomach. The surgeon then carefully releases the stomach from the abdominal wall, exposing the opening created by the gastrostomy. This step is crucial as it allows for proper closure of the stomach's opening. The edges of this opening are debrided, which means any necrotic or unhealthy tissue is removed to promote healing. Following this, the opening in the stomach is closed using sutures, ensuring that the stomach is sealed properly to prevent any leakage. Finally, the incision made in the abdominal wall is also closed, completing the procedure and restoring the integrity of the abdominal wall. This surgical closure is essential for patients who no longer require a gastrostomy tube, as it helps to prevent complications such as infection or herniation at the site of the previous tube placement.
