2025 CPT code 74363
(Active) Effective Date: N/A Radiology - Diagnostic Radiology Feed
Radiological supervision and interpretation for percutaneous transhepatic dilation of a biliary duct stricture, including possible stent placement.
Modifiers 26 (professional component) and TC (technical component) may be applicable if the professional and technical services are billed separately. Modifier 52 (reduced services) may be applicable if the service is significantly reduced.
Medical necessity for 74363 must be supported by documentation demonstrating the presence of a biliary duct stricture causing symptoms or complications that require intervention.The documentation should justify the need for radiological supervision and interpretation during the dilation procedure.
The radiologist is responsible for supervising and interpreting the radiological images during the procedure. This includes guiding the placement of instruments, administering contrast, and monitoring the progress of the dilation and stent placement (if performed).They also interpret the resulting images to assess the success of the procedure.
In simple words: This code covers the radiologist's work in overseeing and interpreting X-ray images during a procedure to open up a narrowed bile duct.A thin tube is inserted through the skin and liver into the bile duct, and dye is injected to make the duct visible on X-ray. The radiologist uses these images to guide a balloon that widens the blockage.A small mesh tube (stent) may also be placed to keep the duct open. This code only bills for the radiologist's expertise in using X-ray imaging to guide and interpret the procedure, not the procedure itself.
This code encompasses imaging supervision and interpretation during a percutaneous transhepatic dilation of a biliary duct stricture.The procedure involves inserting a catheter or endoscope into the bile ducts, administering contrast material, and using fluoroscopy to guide the dilation of the stricture with a balloon.Placement of a biliary stent may also be included. This code represents the radiologist's supervisory and interpretive services, not the interventional procedure itself.
Example 1: A patient with a benign biliary stricture undergoes percutaneous transhepatic dilation with balloon and stent placement. The radiologist supervises and interprets the imaging guidance for the procedure, using fluoroscopy and contrast. Code 74363 is reported for the radiologist's services., A patient presents with jaundice due to a malignant biliary stricture.Percutaneous transhepatic biliary dilation is performed under radiological guidance for palliative relief of the obstruction.A stent is placed to maintain patency. The radiologist's supervision and interpretation are billed with 74363., Following cholecystectomy, a patient develops a postoperative stricture. Percutaneous transhepatic balloon dilation is performed under fluoroscopic guidance by an interventional radiologist.74363 is reported for the imaging supervision and interpretation.
Documentation should include details of the radiological supervision and interpretation, including the type of imaging used (fluoroscopy), the administration of contrast, the location and severity of the stricture, the method of dilation (balloon), and whether a stent was placed.Reports should also document the pre- and post-dilation appearance of the biliary ducts.
