What 43235 covers

A flexible scope is passed through the mouth to examine the esophagus, stomach, and duodenum. When performed, brushings or washings collect cells or material for laboratory analysis; they are part of this service. Gastroenterologists and other physicians trained in upper endoscopy perform it in office, ambulatory, and hospital settings to evaluate upper gastrointestinal symptoms or findings when the examination is diagnostic.

Report this code when inspection, with or without brushings or washings, is performed without a biopsy or therapeutic intervention. The record should support the examined anatomy, findings, and any sampled site and method. A biopsy or endoscopic treatment calls for the corresponding procedure code rather than separate reporting of this diagnostic examination. Medicare assigns a 0-day global period, so same-day preoperative and postoperative care is included. For multiple procedures in one session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate; assistant-at-surgery services are not paid, and 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.

43235 billing questions

When should 43239 be reported instead?

Use 43239 when forceps biopsy is performed during the upper endoscopy. Do not separately report this diagnostic examination for the same session.

Are brushings or washings separately billable?

No. Brushings or washings, when performed as part of the diagnostic examination, are included in 43235.

Can 43235 be reported with an endoscopic treatment?

When the same session includes a therapeutic upper endoscopic procedure, report the procedure performed rather than separately reporting the diagnostic examination.

Should modifier 50 be appended?

No. The CMS bilateral adjustment does not apply, and modifier 50 is inappropriate for this service.

How does Medicare handle multiple procedures in one session?

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.
