What modifier do you use to support a 56605?

To support a 56605 procedure code, you typically use modifier -50 for bilateral procedures if applicable, indicating that the procedure was performed on both sides. If the procedure was performed on a single side but under unique circumstances, other modifiers like -51 for multiple procedures or -59 for distinct procedural service may also be appropriate based on the specific situation. Always ensure to check the guidelines and payer policies for the correct application of modifiers.
