What modifier is used to report reduced services?

The correct modifier used to report reduced services is 52. This modifier indicates that a procedure or service was partially reduced or eliminated at the physician's discretion. It is commonly applied in situations where the service is performed, but less than the usual amount or complexity of the service was provided.

For instance, if a surgical procedure is performed but requires less work than what is typically expected or is partially completed, the use of modifier 52 communicates to payers that the service rendered was diminished compared to what is standard for that code. This is important for accurate billing, as it helps ensure that reimbursement is aligned with the actual level of service provided.

The other modifiers listed serve different purposes; for example, modifier 51 denotes multiple procedures, modifier 53 indicates a discontinued procedure due to extenuating circumstances, and modifier 54 refers to the surgical care aspect when a procedure is split between different providers. Each modifier has a specific context, which is why modifier 52 is the appropriate choice in this case.
