What is the main use for modifier -57?

Modifier -57 is primarily utilized to signify a key pre-operative decision for starting surgery. This modifier is applicable when an evaluation and management (E/M) service is performed on the same day as a surgical procedure, indicating that the E/M service led directly to the decision to perform the surgery.

In this context, the use of modifier -57 highlights that the physician's assessment and the subsequent decision to undertake surgery are both critical elements of the patient's care on that day. This ensures that the E/M service is appropriately reimbursed in addition to the surgical procedure, acknowledging the important role it plays in the overall treatment plan.

The other options do not correctly capture the essence of the modifier’s specific purpose. While consultation and distinct services are certainly important considerations in coding practices, they are not the central focus of modifier -57. Similarly, although there are modifiers indicating repeated procedures or distinct services, they pertain to different coding scenarios and do not relate to the pre-operative decision-making process emphasized by modifier -57.
