A Reminder About Anatomic-Specific Modifiers

In order to ensure that your office is correctly billing modifiers, we encourage you to review the Blue Cross and Blue Shield of North Carolina (BCBSNC) Corporate Medical Policy addressing Modifier Guidelines, which was last revised in December 2013 and available online at:

 As a reminder, anatomic-specific modifiers designate the area or part of the body on which the procedure is performed.  These modifiers allow for automated, accurate processing of claims by BCBSNC.

Specifically, we'd like to remind you of the following guidelines:

  • There are specific anatomic modifiers for eyelids (E1-E4), fingers (FA-F9), toes (TA-T9), and coronary arteries (RC, LC, LD, RI, LM).
  • Modifiers RT and LT designate right and left, respectively.
  • Modifier 50 is used when bilateral procedures are performed on both sides.
