What does modifier -52 signify?

Modifier -52 is used to indicate that a procedure was performed but with limitations or that the service provided was reduced or less extensive than the usual service. This may apply when a provider performs a procedure, but the circumstances prevent the full procedure from being accomplished, perhaps due to patient factors or logistical issues.

By utilizing modifier -52, it communicates to payers that the procedure was partially completed or that a portion of the service was omitted, which can affect reimbursement rates accordingly.

The other options, while relevant to different coding scenarios, do not align with the specific purpose of modifier -52. For instance, bundling of services is generally indicated by other modifiers, and pre-operative care and preparation for surgery usually have distinct modifiers to describe those procedures accurately. Therefore, recognizing the specific usage of modifier -52 in cases of limited procedure performance is essential for proper coding practices.
