CT scan supervision

The radiology suite in our building has asked the cardiology suite to supervise the injection of their CT scans. How is this billed? Stress tests have a supervision code and an interpretation code. CT scans have only technical and professional modifiers, however, cardiology would only be supervising, not interpreting. Would this be considered a purchased service perhaps? Does the supervision need to be done directly in the radiology suite or can it be done on an on-call basis since the cardiology suite is down the hall? Based on your response, please provide the source for me as a reference. Thank you

Supervise means be there for crisis

A doctor is required to be on site when contrast is administered. There is no code for this or charge; it is the radiologist's responsibility. If someone has a reaction, the doctor responds. Best talk to your malpractice carrier about this. If someone codes or dies, your doctor will be part of the lawsuit.

I have no reference except common sense and personal experience.

try this

Ask the radiologists if they would be willing to supervise your stress tests; not read them, just be present. Same thing as your docs supervising their CT scans.
