Here is guidance on when and how to use the GV and GW medical coding modifiers in hospice work for attending physicians.
Question: When and how do we use the GV and GW modifiers in hospice work?
Answer: The GV modifier is placed in field 24D on the CMS 1500 claim form. This is the modifier used when a physician is the attending physician for a hospice patient and not associated with the hospice in any way (employed, contracted, or volunteering), but who is providing a service that is related to the diagnosis for which a patient has been enrolled into hospice.
The GW modifier, on the other hand, is used when a physician is the attending physician for a hospice patient and not associated with the hospice in any way (employed, contracted, or volunteering) who is providing a services that is not related to the diagnosis for which a patient has been enrolled onto hospice.
