New Specific Modifiers for Distinct Procedural Services

Thursday, September 18, 2014  

The Centers for Medicare and Medicaid Services (CMS) is establishing four new Healthcare Common Procedure Coding System (HCPCS) modifiers to define subsets of the -59 modifier, a modifier used to define a “Distinct Procedural Service.” The new modifiers will go into effect as of January 1, 2015 and are as follows:

  • XE - Separate Encounter, A Service That Is Distinct Because It Occurred During A Separate Encounter
  • XS - Separate Structure, A Service That Is Distinct Because It Was Performed On A Separate Organ/Structure
  • XP - Separate Practitioner, A Service That Is Distinct Because It Was Performed By A Different Practitioner
  • XU - Unusual Non-Overlapping Service, The Use Of A Service That Is Distinct Because It Does Not Overlap Usual Components Of The Main Service
