Item Provided Prior to Surgery
  • Prior to surgery, item can be provided and billed when it is medical necessary and coverage criteria is met and documentation is included in ordering physicians medical record. If there is no medical necessity until after surgery, do not provide item prior to surgery
RT/LT Modifiers
  • Effective for claims with dates of service (DOS) on/after 03/01/19, suppliers must bill each item on two separate claim lines using the RT and LT modifiers and 1 UOS on each claim line. Claim lines for HCPCS codes requiring use of the RT and LT modifiers, billed without the RT and/or LT modifiers or with the RTLT on a single claim line, will be rejected as incorrect coding.
