CPT® Code 47543

Add-On Code

Endoluminal biopsy(ies) of biliary tree, percutaneous, any method(s) (eg, brush, forceps, and/or needle), including imaging guidance (eg, fluoroscopy), and all associated radiological supervision and interpretation, single or multiple (List separately in addition to code for primary procedure)

The procedure described by CPT® Code 47543 involves performing endoluminal biopsies of the biliary tree through a percutaneous approach. This technique is utilized to obtain cell or tissue samples from the lumen of a biliary duct, which is essential for diagnosing conditions affecting the biliary system. Endoluminal biopsy is particularly indicated in cases where imaging studies alone are insufficient to distinguish between benign and malignant lesions, especially in patients presenting with biliary stenosis. The procedure can be performed using various methods, including brush, forceps, or needle techniques, and is typically guided by imaging modalities such as fluoroscopy to ensure accurate placement and sampling. In instances where a percutaneous transhepatic drainage catheter is already in place, the procedure can be conducted through this existing access point, simplifying the process. If no catheter is present, a small-gauge needle is inserted through the skin into the liver under fluoroscopic guidance to establish access to the biliary tree. The procedure is comprehensive, as it includes all necessary imaging guidance, supervision, and interpretation associated with the biopsies, whether they are performed as single or multiple procedures. The code for this service is reported separately in addition to the primary procedure code, reflecting the complexity and the resources utilized during the biopsy process.
