Which term denotes an additional code attached to a procedure to reflect special circumstances?

• A. Prefix
• B. Suffix
• C. Modifier
• D. Descriptor

Answer: (C)

In coding, the extra information that signals special circumstances attached to a procedure is conveyed by a modifier. A modifier is appended to the main procedure code to indicate changes like bilateral performance, separate or distinct services, or specific modalities of delivery, without changing the base procedure code itself. Examples include bilateral procedures (modifier 50), multiple/distinct procedures (modifier 59), or left/right differentiation (LT/RT). Prefixes and suffixes are general language terms and don’t represent coding modifiers, while a descriptor is simply the text that explains what a code means, not an added code to reflect special conditions.
