Final answer:
A radiologist would bill the professional component for interpreting films from another facility, providing a diagnostic report separate from the technical component.
Step-by-step explanation:
If a radiologist reads and interprets films from another facility, he or she would bill for the professional component of the radiology services. This billing component refers to the work done by the radiologist in interpreting the images and providing a diagnostic report. These services are separate from the technical component, which includes the actual taking of radiographic images, equipment use, technician services, and costs of materials used during the imaging procedure. Generally, the professional component is billed separately by the radiologist while the technical component is billed by the facility where the images are taken.
