Small intestinal endoscopy, enteroscopy beyond second portion of duodenum, not including ileum; with removal of foreign body(s)

The CPT® Code 44363 refers to a specific medical procedure known as small intestinal endoscopy, specifically an enteroscopy that extends beyond the second portion of the duodenum, and includes the removal of foreign body(ies). This procedure is performed to examine the small intestine, which is a crucial part of the digestive system responsible for nutrient absorption. The small intestine is divided into three main sections: the duodenum, jejunum, and ileum, with the duodenum itself further divided into four portions. The second portion of the duodenum is significant as it is where the bile and pancreatic ducts enter, making it a critical area for examination when foreign bodies are suspected. During the procedure, a flexible fiberoptic endoscope is utilized, which allows for direct visualization of the intestinal tract. The endoscope is inserted through the mouth and advanced through the esophagus and stomach into the small intestine. The procedure is typically performed under sedation, and local anesthetic may be applied to the throat to facilitate the insertion of the endoscope. The primary goal of this endoscopic examination is to locate and remove any foreign bodies that may be lodged within the small intestine, which can cause obstruction or injury. The removal techniques may vary depending on the nature of the foreign body, whether it is smooth-edged, impacted, or sharp. Following the removal, the endoscope is reintroduced to inspect the small intestine for any signs of perforation or other injuries that may have occurred during the presence of the foreign body.
