Gastroenterology
About 43261: ERCP with duct biopsy
Reports ERCP with forceps tissue sampling of a biliary or pancreatic duct abnormality, such as a suspected lesion or stricture.
During ERCP, a gastroenterologist advances a side-viewing endoscope through the mouth to the duodenum, accesses the biliary or pancreatic duct, and obtains one or more tissue samples. The service is used to investigate a ductal abnormality, including a suspected tumor or stricture. ERCP is typically performed in a hospital or ambulatory surgery center, often with fluoroscopic guidance.
Report this code when the ERCP includes biopsy; brushing or washing for specimens alone is a different service. The procedure report should identify the sampled site and document the tissue-sampling work. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When related endoscopies are performed together, 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 billing are not permitted.

43261 billing questions
How is this different from 43260?
Use 43261 when ERCP includes tissue biopsy. Code 43260 describes ERCP with specimen collection by brushing or washing rather than biopsy.
Can brushing or washing be reported with the biopsy?
The biopsy code identifies the tissue-sampling ERCP service. Document each method performed and apply applicable coding edits and endoscopy-family pricing when related endoscopies are reported together.
Does modifier 50 apply if both sides of the biliary system are sampled?
No. CMS identifies bilateral adjustment as inapplicable to this code, and modifier 50 is inappropriate.
Can an assistant surgeon or co-surgeon be billed?
Medicare does not pay an assistant at surgery for this code. Co-surgeons and team surgery are not permitted.
What documentation supports reporting 43261?
The ERCP report should describe the ductal abnormality, the site sampled, and the biopsy performed. It should distinguish tissue biopsy from brushing or washing alone.
Does the code include same-day postoperative care?
Yes. The code has a 0-day global period, which includes same-day preoperative and postoperative care.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
