Question: Our surgeon performed an esophagoscopy on a Medicare patient before the insertion of a Maloney bougie dilator. What is the correct code, and is it different for a guide wire dilation?

Answer: No matter how you code it, Medicare’s multiple-procedure rules will apply and you can expect 100 percent payment for the primary and highest paying procedure. Depending on the extent of esophagoscopy procedure performed by your surgeon, you may report one of the following:
For the Maloney dilation, you should report 43450 (Dilation of esophagus, by unguided sound or bougie, single or multiple passes). If the surgeon uses a fluoroscope during this procedure, you should use code 74360 (Intraluminal dilation of strictures and/or obstructions [e.g., esophagus], radiological supervision and interpretation) with modifier 26 (Professional component) for the physician’s interpretation. You can expect reimbursement of 50 percent of the standard fee here, also.
Sometimes surgeons need to use guide wires with bougie dilations, usually when strictures either become too tight or take on irregular shapes. When coding this type of procedure, consider the exact sequence of events that the surgeon undertook in placement of the bougie. In such a case, you can use either of the following codes:
If the surgeon sends a dilator over a guide wire, you should code 43453 (Dilation of esophagus, over guide wire). For the fluoroscopy, use code 74360 with modifier 26 attached.
Heads up: You can spot endoscopic dilations using a guide wire if you go through the procedure notes with a keen eye. Endoscopic procedures are easy to spot by the use of the words “Savary” or “American,” two common guide-wire dilator brand names. If you find either of these keywords in the doctor’s notes, be on the lookout for a guide-wire dilation.
