Final answer:
In CPT coding, the term 'See' is the correct cross-reference term that directs coders to another term in the index for the accurate code or code series.
Step-by-step explanation:
The best example of a CPT (Current Procedural Terminology) index cross-reference term among the given options is d. See. In the context of CPT coding, cross-reference terms guide coders to the correct code or code series by directing them to look at another term that may have a more accurate description of the procedure. The term 'See' specifically instructs the coder to refer to another place in the index to find the correct codes. For example, if the coder looks up a procedure and the index says 'See', it means that the procedure is likely listed under a different term or category, and the coder should look there to find the right codes.
