CPT® Code 44386

The CPT® Code 44386 refers to the endoscopic evaluation of a small intestinal pouch, which may include structures such as a Kock pouch or an ileal reservoir configured in an S or J shape. A Kock pouch is a specialized type of continent ileostomy created from the terminal ileum following a colectomy. This pouch features a reservoir that retains bowel contents until the patient opts to empty it using a catheter inserted through a nipple-type valve that exits to the skin. In contrast, S and J pouches are types of ileoanal reservoirs constructed from the small intestine after a total colectomy. These pouches are designed to connect to the anal canal and are characterized by the specific looping of the intestine, which is either in an S or J formation, as determined by the surgeon during the procedure. Typically, the creation of S and J pouches is performed in a two-stage process, where an initial loop ileostomy is established to allow the internal pouch to heal before re-establishing continuity of the bowel. The endoscopic evaluation performed under this code is crucial for monitoring the health and condition of the small intestinal pouch. During the procedure, an endoscope is introduced into the pouch through the stoma or valve, allowing for a thorough inspection of the mucosal lining. If any suspicious areas are identified, biopsy forceps can be utilized to obtain tissue samples for further analysis, ensuring that any potential issues can be addressed promptly and effectively.
