I'm not real strong in my understanding of coding when it comes to residents so I reached out to my friend Suzan who is. Here s her reply.

When is the proper time to use the GC modifier? The GC modifier is applied to ALL services billed to Medicare and done by Residents. This would be used for both outpatient/inpatient services and also office services. I code for Inpatient Medicine doctors. I am aware that the initial admission requires an AI Modifier. When there's a resident with the Attending, the AI/GC is used on the initial as well. Do we use the GC modifier only for Inpatient follow up when the residence has seen and examined the patient? If there is an appropriate note (along with an attestation) done by the attending physician, then the GC would be added to those services. I know Medicaid does not use the GC modifier. I don’t believe so. What other insurances do not use this?
Thank you,
