CPT® Code 44373

Small intestinal endoscopy, enteroscopy beyond second portion of duodenum, not including ileum; with conversion of percutaneous gastrostomy tube to percutaneous jejunostomy tube

The CPT® Code 44373 refers to a specific medical procedure known as small intestinal endoscopy, particularly focusing on enteroscopy beyond the second portion of the duodenum, which does not include the ileum. This procedure involves the conversion of a percutaneous gastrostomy tube to a percutaneous jejunostomy tube. In simpler terms, it is an endoscopic examination of the small intestine that allows healthcare providers to visualize and assess the jejunum, which is the middle section of the small intestine, located after the duodenum. The jejunum plays a crucial role in nutrient absorption, and the procedure is often performed on patients who are unable to consume food or liquids orally due to various medical conditions. During the procedure, a percutaneous endoscopic jejunostomy (PEJ) tube is placed in the jejunum to provide nutritional support directly to the digestive system. The process begins with the administration of an anesthetic spray to numb the mouth and throat, followed by the insertion of a flexible fiberoptic endoscope. This endoscope is carefully advanced through the patient's mouth and into the gastrointestinal tract, allowing the physician to visualize the mucosal surfaces of the small intestine. The examination extends beyond the second portion of the duodenum, ensuring that any abnormalities in the jejunum can be identified and documented. In cases where a patient has an existing gastrostomy tube, this procedure allows for the conversion to a jejunostomy tube, which is often necessary when there are concerns about aspiration of stomach contents into the lungs. The conversion process involves the removal of the gastrostomy tube and the careful placement of a new feeding tube into the jejunum, ensuring that the patient continues to receive adequate nutrition while minimizing the risk of complications.
