CPT® Code 44376

Small intestinal endoscopy, enteroscopy beyond second portion of duodenum, including ileum; diagnostic, with or without collection of specimen(s) by brushing or washing (separate procedure)

A small intestinal endoscopy, specifically referred to as enteroscopy beyond the second portion of the duodenum, is a diagnostic procedure that allows for the examination of the small intestine, including the ileum. This procedure can be performed with or without the collection of specimens, which may involve brushing or washing techniques. The process begins with the administration of an anesthetic spray to numb the mouth and throat, facilitating the insertion of a flexible fiberoptic endoscope. The patient swallows the endoscope, which is then carefully advanced through the esophagus and into the duodenum, guided by direct visualization. During the examination, the mucosal surfaces of the duodenum, jejunum, and ileum are thoroughly inspected for any abnormalities. Following the initial inspection, the endoscope is withdrawn, allowing for a second evaluation of the intestinal mucosa. In the context of CPT® Code 44376, cell samples can be collected by introducing saline fluid into the small intestine and retrieving it, while separate procedures, such as those coded under CPT® Code 44377, involve obtaining tissue samples through biopsy techniques. These samples are subsequently sent for laboratory analysis to aid in diagnosis and treatment planning.
