I am a pro fee auditor and know little to nothing about hospital billing. We have a client, hospital, that would like to contract providers to read their EKGs. This would be a purchased service. They, hospital, want to know how would they bill this. Since I know nothing about hospital billing I do not know what to tell them and cannot find anything in research. Would they use the same code as a practice, 93000? How would they acknowledge the read/interpretation was a purchased service? Any help would be greatly appreciated.
