What 43226 covers

A gastroenterologist or other qualified endoscopist uses a flexible scope passed through the mouth to examine the esophagus, place a guidewire, and dilate a narrowed segment over the wire. Common indications include an esophageal stricture causing difficulty swallowing. The service may be performed in an endoscopy center or hospital, and sometimes in an office setting.

Select this code when the dilation is performed over a guidewire; balloon dilation and retrograde approaches have distinct codes. Document the narrowing, the guidewire-assisted technique, and the dilation performed. The 0-day global period includes routine same-day preoperative and postoperative care. When related endoscopies are performed together, CMS endoscopy-family pricing applies. Modifier 50 is inappropriate for this service. Medicare does not pay an assistant at surgery, and co-surgeon and team-surgery reporting are not permitted.

43226 billing questions

When should this code be chosen over balloon-dilation codes?

Use 43226 when the esophagus is dilated over a guidewire. Balloon dilation is reported with a code specific to the balloon method and size.

Can the diagnostic esophagoscopy be billed separately?

The scope examination used to perform the dilation is part of the reported service; do not separately report a diagnostic examination for that same work.

What documentation supports 43226?

Document the esophageal narrowing, the flexible transoral approach, guidewire placement, and dilation over the wire.

Does modifier 50 apply if the narrowing involves both sides?

No. CMS identifies bilateral adjustment as inappropriate for this code; report the service performed without modifier 50.

Can an assistant or co-surgeon be reported?

Medicare does not pay an assistant at surgery for this service. Co-surgeons and team surgery are not permitted.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. 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.
