When is modifier -G2 required?

Modifier -G2 is specifically required for time-sensitive surgical procedures that must be performed under certain protocols. This modifier indicates that the procedure was carried out in a timely manner according to the guidelines set for that particular surgery, which is crucial in contexts where delays can impact the patient's outcome. It ensures that the healthcare provider is recognized for complying with standards that prioritize prompt treatment, especially in urgent cases.

In contrast, modifier -G2 is not related to follow-up care, outpatient procedures, or preventive care scenarios, as those situations do not emphasize the need for timing protocols associated with surgical procedures. Thus, the focus of modifier -G2 on timeliness in surgical interventions distinguishes it from the other options presented.
