Wiki X modifer for 70544/73110

[TSHCOLEMAN]

Will someone please help me with these new "X" modifiers? Which one should I use for 70554 and 73110 for the hospital side? I code ED's for the hospital.

Thanks,

Tamara

X modifiers instead of 59

To start, let?s quickly define the four newest HCPCS modifiers, also commonly referred to as -X{EPSU} modifiers. The acronym*EPSU is made up of the last letter of the new modifiers.
Modifier XE
Separate Encounter: A service that is distinct because it occurred during a separate encounter.
Modifier XP
Separate Practitioner: A service that is distinct because it was performed by a different practitioner.
Modifier XS
Separate Structure: A service that is distinct because it was performed on a separate organ/structure.
Modifier XU
Unusual Non-Overlapping Service: The use of a service that is distinct because it does not overlap usual components of the main service.
