Modifier 59 is used to indicate that two or more procedures were performed at different sessions, different procedures or surgeries, different sites or organ systems, or involved separate incisions or excisions. In this case, since the procedures are performed via separate incisions at two connecting interspaces, modifier 59 is the appropriate choice to denote that these are distinct procedural services.
