In the context of CPT modifiers, what does TC stand for?

In the context of CPT modifiers, TC stands for Technical Component. This modifier is used to indicate that a service or procedure involves only the technical aspects of a diagnostic test or imaging service, as opposed to the professional component, which includes the interpretation or report of the results obtained from that test or procedure. For instance, when a facility provides a radiological service, the TC modifier distinguishes the technical work performed, such as the equipment and the technical personnel involved, from the professional services rendered by a radiologist who interprets the images.

The other options do not accurately define the TC modifier. Total charge does not align with the specific terminology used in CPT modifiers. Therapeutic consultation and Trial code are unrelated terms that do not have relevance to the CPT modifier context as established by the American Medical Association.
