There are a family of codes within the endoscopy section of the American Medical Association’s (AMA’s) Current Procedural Terminology (2022/CPT®) that are appropriate to use when reporting biliary endoscopy. The most common scenario in IR is to use the device via an existing tract or biliary drainage catheter to directly visualize the biliary system, and subsequently remove biliary stones. In this clinical scenario, it is appropriate to report CPT® code 47554 (Biliary endoscopy, percutaneous via t-tube or other tract with removal of calculus/calculi). Following the stone removal, if the existing biliary drainage catheter is replaced under imaging guidance, it would be appropriate to also report CPT® code 47536 (Exchange of biliary drainage catheter (e.g., external, internal-external, or conversion of internal-external to external only), percutaneous, including diagnostic cholangiography when performed, imaging guidance (e.g., fluoroscopy), and all associated radiological supervision and interpretation).
Additional codes in the biliary endoscopy family are as follows:
- 47552—Biliary endoscopy, percutaneous via T-tube or other tract; diagnostic, with collection of specimen(s) by brushing and/or washing, when performed (separate procedure)
- 47553—Biliary endoscopy, percutaneous via T-tube or other tract; with biopsy, single or multiple
- 47554—Biliary endoscopy, percutaneous via t-tube or other tract with removal of calculus/calculi)
- 47555—Biliary endoscopy, percutaneous via T-tube or other tract; with dilation of biliary duct stricture(s) without stent
- 47556—Biliary endoscopy, percutaneous via T-tube or other tract; with dilation of biliary duct stricture(s) with stent
When combining percutaneous biliary procedures (47531–47544) with endoscopic biliary procedures (47552–47556), documentation should be clear what approach/technique was used to perform each procedure. If both techniques are used to accomplish a single intervention, one should report the primary guidance technique that was used and only report one code to represent a single procedure. It should also be noted that these code families do not allow for co-surgeon modifier (-62). Only one provider can report a single code for the same session.
