Gastroenterology endoscopy
About 43235: Diagnostic upper GI endoscopy with sampling
Reports a flexible upper endoscopic examination of the esophagus, stomach, and duodenum, including brush or wash cytology when performed without biopsy or therapy.
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.

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?
The highest-valued procedure is paid in full; other procedures in the same session are paid at 50%. The 0-day global period includes same-day preoperative and postoperative care.
Can an assistant or co-surgeon be billed for this procedure?
Medicare does not pay an assistant at surgery for this service. Co-surgeons and team surgery are not permitted.
