CPT® Code 43456

Deleted

The procedure described by CPT® Code 43456 involves the dilation of the esophagus using a retrograde approach, which is particularly indicated when traditional endoscopic access through the mouth is not feasible. This situation may arise due to various conditions, such as injuries or obstructions of the trachea, which can occur in cases of burns or malignancies. The retrograde approach necessitates an incision in the abdomen, allowing access to the stomach. Once the stomach is incised, a balloon catheter is carefully advanced to the area of the esophagus that is narrowed or obstructed. The balloon is then inflated to widen the stricture, and this inflation may be repeated multiple times to achieve the desired diameter. Alternatively, a series of progressively larger tubes can be utilized to gradually dilate the stricture. After the procedure, the stomach incision is sutured closed, followed by the closure of the abdominal incision in layers, ensuring proper healing and recovery.
