Answer: Code 44373 (Small intestinal endoscopy, enteroscopy beyond second portion of duodenum, not including ileum; with conversion of percutaneous gastrostomy tube to percutaneous jejunostomy tube) should be used to report this procedure because the j-tube was inserted by passing it through a g-tube that was already in place.
J-tubes can also be inserted percutaneously, through an incision in the stomach under endoscopic guidance. That procedure would be reported with 44372 ( with placement of percutaneous jejunostomy tube).
