When modifier 54 is assigned payment---------- portion of the surgical procedure is being requested?

Modifier 54 is used to indicate that only the surgical portion of a procedure is being billed separately, while the preoperative and postoperative care is not included. This modifier is typically applied when a surgeon performs a procedure but the patient will receive follow-up care from another provider. By using modifier 54, the billing reflects that the payment requested is specifically for the surgical services rendered, excluding any associated care outside of that procedure.
