What 43257 covers

This service combines upper gastrointestinal endoscopy with thermal treatment directed at the gastroesophageal junction and lower esophageal sphincter to address GERD. A gastroenterologist typically performs it in an endoscopy suite or hospital outpatient setting, using an endoscopic device to deliver energy to the treatment area. It is not the code for a diagnostic examination alone or for treating a separate bleeding site or mucosal lesion.

Choose the code when the endoscopy and therapeutic thermal application are documented, including the GERD indication and treatment target. When related endoscopies are performed together, CMS endoscopy-family pricing applies. The 0-day global period includes same-day preoperative and postoperative care. Modifier 50 is inappropriate because this service is not a bilateral procedure. Assistant-at-surgery payment is statutorily restricted; co-surgeons and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

How to choose

43235Upper GI endoscopyDiagnostic, brushings or washings
Use 43257 when thermal treatment for GERD is delivered. Use 43235 for a diagnostic upper endoscopy without that therapeutic treatment.
43270Lesion ablationUpper GI endoscopy
43270 treats an endoscopically identified lesion with ablation. 43257 is for thermal treatment directed at GERD, not a focal lesion.
43255Bleeding controlAny endoscopic hemostasis method
43255 is reported for endoscopic control of bleeding. 43257 describes thermal treatment for GERD, not hemostasis.

43257 billing questions

When should this be reported instead of a diagnostic EGD?

Report 43257 when thermal treatment for GERD is actually performed during the endoscopy. A diagnostic examination without that treatment is represented by 43235.

Can the diagnostic EGD be reported separately in the same session?

The examination that supports the therapeutic procedure is integral to the service; do not separately report a diagnostic EGD for that same examination.

How are related endoscopies priced when performed together?

CMS endoscopy-family pricing applies when related endoscopies are performed together. Document each procedure performed and its treatment target.

Which modifiers are appropriate for bilateral treatment or multiple surgeons?

Modifier 50 is inappropriate for this service. CMS restricts assistant-at-surgery payment, and co-surgeons and team surgery are not permitted.

What documentation supports reporting 43257?

Document GERD as the indication, the endoscopic treatment site, and that thermal energy was delivered for reflux treatment—not merely that the area was examined.

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.
