CPT® Code 44369

Small intestinal endoscopy, enteroscopy beyond second portion of duodenum, not including ileum; with ablation of tumor(s), polyp(s), or other lesion(s) not amenable to removal by hot biopsy forceps, bipolar cautery or snare technique

The CPT® Code 44369 refers to a specific medical procedure known as small intestinal endoscopy, specifically an enteroscopy that extends beyond the second portion of the duodenum, excluding the ileum. This procedure involves the endoscopic examination of the small intestine, allowing for the identification and treatment of various abnormalities such as tumors, polyps, or other lesions. These lesions are not suitable for removal using standard techniques like hot biopsy forceps, bipolar cautery, or snare techniques, which are typically employed for less complex cases. The procedure is performed using a flexible fiberoptic endoscope, which is a specialized instrument designed to visualize the interior of the gastrointestinal tract. The endoscope is inserted through the mouth and advanced through the esophagus into the stomach and then into the duodenum, which is the first section of the small intestine. The duodenum is anatomically divided into four portions: the duodenal bulb or cap, the descending portion, the transverse portion, and the ascending portion. During the procedure, the mucosal surfaces of the small intestine are carefully inspected for any abnormalities beyond the second portion of the duodenum, and if any lesions are found, they are treated through ablation. Ablation is a technique that involves the destruction of the lesion using methods such as laser therapy, which is delivered through the endoscope to ensure precision and effectiveness in targeting the abnormal tissue. This procedure is crucial for managing conditions that may not be amenable to simpler removal techniques, thereby providing a therapeutic option for patients with complex gastrointestinal issues.
