A coding specialist should use which modifier to report reduced services?

• A. -50
• B. -51
• C. -52
• D. -53

Answer: (C)

Modifier 52 is used to report reduced services when a procedure is performed with less than the full scope or duration planned. This indicates the service was partially performed or limited in some way due to circumstances—such as the procedure starting but being shortened or adjusted during the course of the work. In CPT coding, this modifier communicates that the service wasn’t carried out in its entirety, without saying the procedure was completely canceled. Other modifiers serve different purposes: modifier 50 is for bilateral procedures (service performed on both sides), modifier 51 is for multiple procedures performed in the same session, and modifier 53 is for a discontinued procedure (started but not completed). The question asks specifically about reporting reduced services, which is why the appropriate modifier is 52.
