What code would you use for endoscopic catheterization of the biliary ductal system in professional radiology?

1. 74328

2. 74328-26

3. 74328-27

4. 74328-25

The correct answer is: 74328-26

The code that is used for endoscopic catheterization of the biliary ductal system in professional radiology is indeed selected based on specific modifiers that indicate the nature of the service provided. The code 74328 itself typically refers to imaging conducted using contrast media for biliary drainage, but when you add the -26 modifier, it indicates that the professional component of the service is being billed. In professional services like radiology, the -26 modifier is applied to signify that a professional service was performed, as opposed to the technical component that involves the operation of the equipment and materials. This differentiation is essential for proper billing and reimbursement purposes. The selection of the code with the -26 effectively shows that the radiologist interpreted the images and provided the professional opinion based on the services rendered for the endoscopic catheterization of the biliary ductal system. Understanding the importance of this modifier is crucial for accurate coding and ensuring proper communication between healthcare providers and insurance entities.
