About 47550: Intraoperative biliary endoscopy
Reports direct endoscopic inspection of the bile ducts during an operation, such as cholecystectomy with duct exploration, as an add-on to the primary procedure.
During an operation, the surgeon passes an endoscope into the biliary tree to inspect the ducts directly. This may help assess the common bile duct when stones or another duct abnormality are suspected during gallbladder or bile duct surgery. The service is performed in the operating room as part of the operative encounter; it is not the same as imaging the ducts with contrast or endoscopy through a percutaneous access tract.
Report 47550 only with an eligible primary procedure, not as a stand-alone service. The operative report should identify the primary operation and document that biliary endoscopy was performed, including the duct examined and relevant findings. CMS treats this as an add-on paid within the primary procedure’s global period, so it does not establish a separate global period. The endoscopic inspection is distinct from the primary operation’s description; select the primary code according to the operation actually performed.

47550 billing questions
Can 47550 be billed by itself?
No. It is an add-on code and must be reported with an eligible primary procedure.
How is 47550 different from 47563?
47550 represents endoscopic inspection of the bile ducts during surgery. 47563 describes laparoscopic cholecystectomy with cholangiography, which uses contrast imaging rather than direct endoscopic viewing.
Does 47550 create its own global period?
No. CMS places its payment within the primary procedure’s global period; it does not establish a separate global period.
What should the operative note support?
Document the primary operation and the intraoperative endoscopic examination of the biliary tree, including the duct examined and the findings.
Is percutaneous biliary endoscopy reported with 47550?
No. 47550 is for endoscopy performed intraoperatively; percutaneous biliary endoscopy codes describe procedures through percutaneous access.
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.
