Two procedures usually bundled by NCCI are performed as truly distinct services with clear independent documentation. Which modifier family is used only when distinct-service criteria are met?
Select an answer to reveal the explanation.
Short Explanation
Modifier 59 (or the XE/XP/XS/XU cousins) is a scalpel, not a butter knife—only for truly distinct services that NCCI would otherwise glue together. Documentation has to prove independence.
Full Explanation
Modifier 59 and the XE/XP/XS/XU subset communicate a distinct procedural service that would otherwise be bundled under NCCI PTP edits, and they require documentation of independent encounters, sites, or practitioners as applicable. Modifier 24 concerns unrelated E/M in a global period; 57 marks decision for surgery; 26 marks professional component—not NCCI distinct-procedure unbundling.
