What is represented by modifier -11?

Modifier -11 is used to indicate that a service has been performed more than once on the same day by the same provider. This modifier is important in situations where a procedure is repeated or when multiple procedures are performed during a single session. By using modifier -11, the healthcare provider communicates that there are additional services provided that may require separate consideration for payment purposes.

This modifier is typically used in conjunction with other procedural codes to clarify that these services are not duplicates but rather necessary components of patient care on that particular date. Understanding this modifier is crucial for accurate billing and ensuring that providers are appropriately reimbursed for their services.

The other options do not align with the function of modifier -11. For example, reducing a service or indicating a preventive nature does not convey the repetition of a service, nor does it indicate a surgical procedure specifically. Each of these other options pertains to different modifiers that serve distinct purposes in the context of medical coding and billing.
