CPC - Radiology, Pathology and Laboratory, and Medicine - Section 2.1

Assign CPT radiology codes, applying the professional, technical, and global component split and the rules for contrast and supervision and interpretation.

Code diagnostic radiology, ultrasound, nuclear medicine, and radiation oncology services, and split a service into its professional component (modifier 26) and technical component (modifier TC) versus a global service when one provider performs both. Recognise the with-and-without-contrast rules and the separate supervision and interpretation codes that pair with an interventional procedure.

A diagnostic radiology service can be divided into a professional component and a technical component, reported with modifiers 26 and TC. Which description correctly identifies what the professional component of such a service comprises?

  • AThe imaging equipment, film or digital media, supplies, and the technologist's time for the study
  • BThe physician's supervision of the study, interpretation of the images, and the signed written report Correct
  • CThe physician's interpretation together with the room, equipment, and the technologist's time combined
  • DThe technologist's positioning of the patient and acquisition of the images under a physician's order
The professional component of a diagnostic radiology service is the physician's supervision, interpretation, and signed written report, reported with modifier 26. CPT and HCPCS split a diagnostic imaging service into a technical component (equipment, supplies, and technologist time, modifier TC) and a professional component (the physician's supervision, interpretation, and signed written report, modifier 26). Reporting both together yields the global service.

Why A is wrong: Tempting because these are genuine cost elements of imaging, but equipment, supplies, and technologist time form the technical component (TC), not the professional component.

Why B is correct: Correct, because the professional component is the physician's supervision, interpretation, and signed written report, reported with modifier 26.

Why C is wrong: Tempting because it includes the interpretation, but adding the room, equipment, and technologist time describes the global service, not the professional component alone.

Why D is wrong: Tempting because image acquisition is essential to the study, but acquiring the images is technical work, not the physician's professional component.
