What 47542 covers
An interventional radiologist uses percutaneous access and imaging guidance to position and inflate a balloon in a narrowed bile duct or at the ampulla. The goal is to widen a stricture that impedes bile flow, such as a narrowing within the biliary tree or at its outlet into the small bowel. The service may occur during an image-guided biliary intervention in a hospital or other procedural setting.
Report 47542 as an add-on with a primary procedure, not by itself. Documentation should identify the treated duct or ampulla, the narrowing and its clinical significance, and the balloon dilation performed. The record should also support that the dilation is distinct from work already included in the primary service; for example, stent-placement codes include pre- and post-dilation when performed. CMS treats this add-on as paid within the primary procedure’s global period, so it has no separate payment outside that primary procedure.

47542 billing questions
Can 47542 be billed by itself?
No. It is an add-on code and must be reported with a qualifying primary procedure for the same intervention.
How is dilation distinguished from biliary stent placement?
47542 describes balloon dilation of a biliary narrowing. Stent-placement services include pre- and post-dilation when performed, so do not separately report 47542 for dilation that is part of that stent service.
What documentation supports reporting 47542?
Document the target duct or ampulla, the narrowing treated, the balloon dilation performed, and the associated primary procedure. The record should clarify when the dilation is separate from work included in that primary service.
Does 47542 have its own global period?
CMS treats it as an add-on paid within the primary procedure’s global period. It is not independently reported outside the primary procedure.
Is 47542 used to remove a bile duct stone?
No. It represents balloon dilation, not calculus extraction. Code 47544 describes percutaneous removal of duct or gallbladder calculi.
