CPT® Code 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)

The procedure described by CPT® Code 47552 involves a biliary endoscopy performed percutaneously through a T-tube or another external biliary drainage tract. This diagnostic procedure utilizes a flexible fiberoptic endoscope, which is a thin, tube-like instrument equipped with a light and camera, allowing for visualization of the bile ducts. During the procedure, the endoscope is carefully inserted through the T-tube or drainage tract and advanced into the bile ducts. The primary objective is to inspect the bile ducts for any signs of disease or abnormalities, such as blockages, inflammation, or tumors. In conjunction with the visual inspection, cell samples can be collected through a technique known as brushing or by washing saline fluid into the bile duct, which helps to gather cellular material. These samples are then sent to a laboratory for cytology evaluation, which is a separate reportable service. It is important to note that this procedure is classified as a separate procedure, indicating that it is distinct from other related interventions, such as biopsy procedures, which may involve different techniques and coding, such as those described in CPT® Code 47553.
