The professional component covers the radiologist's intellectual work — reviewing the images, interpreting the findings, formulating a diagnosis, and producing the written radiology report. This is what the radiologist bills personally, using Modifier -26, when they do not own the imaging equipment being used. Hospital-based radiologists, teleradiologists, and physicians at independent imaging centers typically bill only the professional component.
Image review and interpretation by physician
Written radiology report creation
Physician time and professional expertise
Consultation with ordering physician when needed
Critical finding communication documentation
-26
Professional Component Only — radiologist interpretation
-52
Reduced Services — partial interpretation documented
Billing the global fee (no modifier) when only the professional component is appropriate creates a duplicate billing conflict with the facility's TC claim — triggering denial of both claims and potential overpayment recoupment demands.
