Separate Procedures: Modifier 59 must be used to bypass payment consolidation for separate procedures. Modifiers XE, XS, XP and XU will not bypass consolidation for Separate Procedures.
Distinct Medical Visits: Modifiers 25, XE, XS, XP and XU can be used to identify distinct medical visits for separate payment when reported with a significant procedure. The X modifiers are not required so you can choose to always use modifier 25 in this scenario.
