CPT® Code 44360

Small intestinal endoscopy, enteroscopy beyond second portion of duodenum, not including ileum; diagnostic, including collection of specimen(s) by brushing or washing, when performed (separate procedure)

The CPT® Code 44360 refers to a specific procedure known as small intestinal endoscopy, specifically an enteroscopy that extends beyond the second portion of the duodenum, excluding the ileum. This procedure is primarily diagnostic in nature and may involve the collection of specimens through brushing or washing techniques, which are performed as a separate procedure. The duodenum, which is the first section of the small intestine, is anatomically divided into four distinct portions: the duodenal bulb (or cap), the descending portion, the transverse portion, and the ascending portion. During the procedure, an anesthetic spray is applied to numb the mouth and throat, facilitating the insertion of a flexible fiberoptic endoscope. This endoscope is advanced through the patient's esophagus and into the duodenum, allowing for direct visualization of the mucosal surfaces. The examination may extend into the jejunum, the section of the small intestine that follows the duodenum, but it does not include the ileum, which is the final part of the small intestine. Throughout the procedure, any abnormalities observed are meticulously noted. Additionally, if necessary, cell samples can be collected by introducing saline fluid into the small intestine and retrieving it, or by performing biopsies using specialized forceps. The collected samples are then sent for laboratory analysis, which is reported separately. This comprehensive examination is crucial for diagnosing various gastrointestinal conditions and ensuring appropriate patient management.
