This change affects only organizations that chose the X modifier set in place of modifier 59.
Modifier 59 stays on the lines CMS excludes. Per CMS guidance (MLN1783722), modifier 59 and its X modifier subsets identify services other than evaluation and management. E/M services use modifier 25 instead. The autocoder no longer converts a 59 into XE or XS on an E/M line, an anesthesia line, or a qualifying circumstance line. A modifier 59 that arrives on one of those lines stays 59.
The catch-all XU rule already worked this way. The XE rule (return to the operating room) and the XS rule (separate structure) now follow the same exclusion.
What to look out for: if your organization uses the X modifier preference, expect 59 to remain on E/M, anesthesia, and qualifying circumstance lines. Other lines still receive the X modifiers as before. Organizations that bill with modifier 59 see no change at all.
