Hello All, I am trying to find a list of how ESI resources are grouped/classified. For instance CT and X-ray are 2 different resources, all labs are 1 resource and CT and MRI are 2 different resources, is an EKG considered its own resource or is it included with say radiology (an x-ray and ekg = 1 resource or 2 resources? Is an US its own resource or included with radiology, etc.? I have searched everywhere and cannot seem to find a list showing how resources are grouped. Thanks!
