What 43248 covers

During upper endoscopy, the physician passes a guide wire through the narrowed esophagus and advances a dilator over it to widen the passage. Gastroenterologists and other physicians trained in endoscopy commonly perform this for symptomatic esophageal strictures, such as narrowing that causes difficulty swallowing, in hospital outpatient departments and ambulatory surgery centers.

Choose this code when the documented dilation is performed over a guide wire; record the esophageal site, the narrowing treated, and the wire-guided technique. A balloon dilation of the esophagus is represented by a different code. This service has a 0-day global period, so same-day preoperative and postoperative care is included. When related endoscopies are performed together, CMS endoscopy-family pricing applies. Modifier 50 is inappropriate. CMS does not pay for an assistant at surgery, and co-surgeons and team surgery are not permitted for this service.

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.

43248 billing questions

How does this differ from code 43249?

Code 43248 represents dilation over a guide wire. Code 43249 is used for esophageal balloon dilation with a balloon smaller than 30 mm.

Can the diagnostic EGD be reported separately?

The endoscopic inspection is part of the therapeutic procedure when performed to guide the dilation. Do not separately report a diagnostic EGD for that same work.

What documentation supports code 43248?

Document the esophageal narrowing treated and that dilation was performed over a guide wire. The record should support that the service was not balloon dilation.

Should modifier 50 be appended?

No. Bilateral adjustment is inappropriate for this service, so modifier 50 should not be used.

How are related endoscopies handled when performed in the same session?

CMS endoscopy-family pricing applies when related endoscopies are performed together. The procedure has a 0-day global period, with same-day preoperative and postoperative care included.

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.
