  • Modifier for Injection Performed During Global Period

    During the global period where the injection is performed for a diagnosis that differs from the surgery, is modifier -58 or -79 appropriate?

    If the diagnosis is completely unrelated to the reason for the surgery, then modifier -79 is correct. Just because there is a different diagnosis, this does not necessarily mean it is unrelated.

    If it is related and considered therapy following the major surgery, report modifier -58. 

    See the modifier reference guides provided on the Coding Resources by Topic webpage.
