What 43453 covers
This service enlarges a narrowed segment of the esophagus by inflating a balloon catheter under fluoroscopic guidance. It may be used for conditions such as a benign stricture, ring, or web that limits passage through the esophagus. A gastroenterologist or interventional radiologist typically performs the dilation in a hospital or outpatient procedure setting. The fluoroscopic balloon approach distinguishes this service from dilation performed through an endoscope or with an unguided bougie.
Report the service when the esophageal dilation uses a balloon catheter with fluoroscopic guidance. Documentation should identify the narrowing and its location, the balloon-catheter technique, and the fluoroscopic guidance used. The 0-day global period includes same-day preoperative and postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate; assistant-at-surgery payment is restricted, and co-surgeon and team-surgery billing are not permitted.

43453 billing questions
How does this differ from 43450?
43453 is for balloon-catheter dilation under fluoroscopic guidance. 43450 describes dilation with an unguided sound or bougie.
When would an endoscopic dilation code be more appropriate?
Use an endoscopic dilation code when dilation is performed through an endoscope. For example, 43249 and 43233 distinguish endoscopic balloon dilation by balloon diameter.
Is same-day postoperative care separately reported?
Same-day preoperative and postoperative care is included in this service's 0-day global period.
Can modifier 50 be used for dilation on both sides?
No. The code's descriptor or anatomy makes bilateral adjustment inappropriate.
How are other procedures in the same session paid?
The highest-valued procedure is paid in full; other procedures in the session are subject to the standard multiple-procedure reduction.
Where these rates come from

Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
