Question: What documentation does my facility need in order to bill for the technical component of 74300?

Answer: In the code description for 74300 (Cholangiography and/or pancreatography; intraoperative, radiological supervision and interpretation), you see that this is a radiological supervision and interpretation (RS&I) code. This means that the entirety of the code involves only the professional component, not the technical component.

Your facility may not bill separately with modifier TC (Technical Component) for this service. If the radiologist performs both radiological supervision and interpretation, you may submit the code as is. If the radiologist only performs supervision or interpretation, not both, you may submit this service using modifier 52 (Reduced Services).
