About 47544: Percutaneous biliary stone removal
Percutaneous biliary stone removal covers image-guided extraction of calculi from bile ducts or the gallbladder during a qualifying biliary access procedure.
This service removes stones from the bile ducts or gallbladder through percutaneous access, using imaging to guide the extraction. It is typically performed by an interventional radiologist in a hospital or other procedural setting when stones are reached through a tract from the skin rather than removed during laparoscopic surgery. The service may involve tract dilation when needed to permit access or extraction.
Report 47544 only with a primary procedure; CMS treats it as an add-on paid within that primary procedure’s global period. The record should identify the percutaneous route, the biliary site treated, the stones addressed, and the extraction performed, along with the associated primary procedure. Do not use it for duct imaging alone, duct dilation alone, or stone removal performed as part of a laparoscopic cholecystectomy.

47544 billing questions
What distinguishes 47544 from biliary duct dilation?
47544 represents percutaneous removal of stones from a bile duct or the gallbladder. Dilation of a biliary duct or ampulla is a different service, reported with 47542 when performed and supported.
Can 47544 be submitted by itself?
No. CMS identifies it as an add-on code that must be billed with a primary procedure and is paid within that procedure’s global period.
Does 47544 describe laparoscopic stone removal?
No. It describes percutaneous treatment through access from the skin. Stone removal during laparoscopic cholecystectomy or laparoscopic duct exploration is not the percutaneous service represented by 47544.
What documentation supports reporting 47544?
Document the percutaneous access route, whether the treated site was a bile duct or the gallbladder, the stone extraction performed, and the primary procedure reported with the add-on.
Is 47544 reported for biliary imaging alone?
No. Cholangiographic injection or imaging without stone extraction does not support 47544; the code is for percutaneous calculus removal.
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.
