CPT® Code 49451

Replacement of duodenostomy or jejunostomy tube, percutaneous, under fluoroscopic guidance including contrast injection(s), image documentation and report

The CPT® Code 49451 refers to the procedure for the replacement of a duodenostomy or jejunostomy tube through a percutaneous approach, utilizing fluoroscopic guidance. This procedure is particularly necessary when a tube has been accidentally dislodged or pulled out, necessitating its replacement to ensure continued access for nutritional support or other medical needs. During the procedure, the existing tube tract is carefully inspected and cleansed to prepare for the insertion of a new tube. The use of contrast media is integral to this process, as it allows for the visualization of the tract and ensures that the new tube is placed correctly. A guidewire is then introduced into the tract, facilitating the smooth passage of the replacement tube into the appropriate anatomical location, such as the stomach or colon. The procedure is conducted under continuous radiographic imaging, which provides real-time feedback on the placement of the tube, ensuring that it is positioned accurately. The code also encompasses the necessary documentation, including image documentation and a written report, which are essential for medical records and billing purposes. For reporting purposes, the code 49451 is specifically designated for the percutaneous replacement of a duodenostomy or jejunostomy tube, while the code 49452 is used for the replacement of a gastrojejunostomy tube.
