What describes a procedure modifier that denotes a service performed independently?

The correct answer is related to the use of the XP modifier, which is used to denote a service that is performed independently of any other services that are being billed. The XP modifier specifically indicates that a procedure was performed on a separate structure or in a distinct anatomical site and is considered to be independent of other services performed that day.

In practice, this means that when you see the XP modifier applied to a CPT code, it enables coders to clarify that the procedure is separate and distinct from other actions, aiding in proper billing and reimbursement. This is particularly significant in scenarios where multiple procedures are billed for the same patient on the same day but should be recognized as independent activities.

Understanding the correct use of modifiers like XP is crucial, as it helps reduce the risk of claim denials by clearly indicating that the services provided are not overlapping or duplicative. Each modifier serves a unique purpose, ensuring that medical billing reflects the actual services performed accurately.
