BCBSNC Claim Filing Guidelines for New CMS “X” Modifiers

CMS has created four new “X” modifiers that will function just as the modifier -59 currently does. Both modifier -59 and these new modifiers are functioning as of January 1, 2015. The new modifiers, which are -XE, -XP, -XS, and –XU, provide more specificity as to the reason for its usage. In order to facilitate correct claims processing, Blue Cross and Blue Shield of North Carolina is requesting that all professional providers submit both the modifier -59, as well as, the “X” modifiers on claims until further notice. The modifier -59 should be listed in the first position and the “X” modifiers should be listed as an additional modifier, which will process as informational only.
