SUBSET OF NEW MODIFIERS FOR MODIFIER 59

CMS implemented four new modifiers as subsets of Modifier 59, effective January 1, 2015. The new modifiers were created to help reduce existing errors associated with the current use of Modifier 59, which indicates distinct and separate procedures performed on the same day by the same provider. Beginning February 16, 2015 CIGNA’s code editing system, ClaimsXtenTM, will recognize the four new modifiers as being valid for claims. Although Cigna and CMS will continue to accept Modifier 59, you are encouraged to use the most specific appropriate modifier available.

The new modifiers are:

• XE (Separate Encounter)
• XS (Separate Structure)
• XP (Separate Practitioner)
• XU (Unusual Non-overlapping Service)
