CPT® Code 44361

Small intestinal endoscopy, enteroscopy beyond second portion of duodenum, not including ileum; with biopsy, single or multiple

The CPT® Code 44361 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 use of a flexible fiberoptic endoscope, which is a specialized instrument designed for visual examination and intervention within the gastrointestinal tract. During the endoscopy, the physician can inspect the mucosal surfaces of the small intestine, particularly the jejunum, for any abnormalities or pathological conditions. The procedure may also involve the collection of tissue samples through biopsies, which can be single or multiple, allowing for further laboratory analysis of the collected specimens. The endoscopic examination is initiated by numbing the patient's mouth and throat with an anesthetic spray, followed by the insertion of a hollow mouthpiece to facilitate the swallowing of the endoscope. The endoscope is carefully advanced through the digestive tract, providing direct visualization of the intestinal lining and enabling the physician to identify any irregularities. This procedure is crucial for diagnosing various gastrointestinal disorders and conditions that may affect the small intestine.
