CPT® Code 43453

The procedure described by CPT® Code 43453 involves the dilation of the esophagus using a guide wire. This technique is utilized when a physician needs to treat an esophageal stricture, which is a narrowing of the esophagus that can occur due to various conditions such as esophageal reflux, benign or malignant lesions, or other injuries and diseases affecting the esophagus. The dilation process is performed without direct visualization of the esophagus, meaning that the physician does not use an endoscope to see the esophagus during the procedure. Instead, the physician employs a series of progressively larger rigid rubber tubes, known as sounds or bougies, which are inserted through the mouth and advanced down into the esophagus to widen the narrowed area. The use of a guide wire in this procedure (as opposed to unguided methods) allows for more precise placement of the dilating instruments. Additionally, it is important to note that a separate esophagram may be conducted prior to the dilation to assess the location and severity of the stricture, and fluoroscopy may be utilized during the procedure to aid in the dilation process.
