Wiki modifier GC

[LScoder2016]

Are there any CPT codes that modifier -GC should not be applied? We use modifier GC for our one specialty, but I wasn't sure if it could cause denials on certain CPT codes. I apply it to our e/m codes and CPT codes for surgery. I understand it's applied when the resident performs a service under the direction of a teaching physician, any other information/guidelines would be greatly appreciated

Per CGS Medicare, it is applicable to all services:
GC Modifier

• Definition: Service has been performed in Part by a Resident under the Direction of a Teaching Physician
• Submit this modifier with all services that are performed by a resident in a teaching facility under the direction of a teaching physician.
  • This modifier is for informational use only and may be submitted with all procedure codes.
  • If other modifiers also apply, submit the other modifiers first, followed by HCPCS modifier GC.
