Modifier RT

Right side (Used to identify procedures performed on the right side of the body)

Instructions

Used to identify procedures performed on right side of body. Be sure to determine if HCPCS modifier RT is applicable to a particular procedure code.

Correct Use

  • Append to appropriate code when body contains a right and left anatomical part of body and a service is performed on right anatomical part
  • Bilateral - when using both RT and LT modifiers, bill on two separate claim lines and one unit of service on each line

Incorrect Use

Note: Modifier RT does not affect allowed amount on a claim; however, lack of modifier can cause denials or development to occur
