I need to have clarification on billing for supplies to insurance carrier. I have always been told and instructed that we must bill the same way for all insurance carriers. This means even though we know that a carrier will not cover a certain procedure or supplie if it is being used we must bill for it. Does anyone have anything in writing on this issue. The example we have we know that one insurance company will pay for surgical tray and another won't . On the insurance that will not pay for the tray do we have to bill the procedure code. If anyone has anything in writting to help me please send to me as I think we need to bill everyone the same and I do not want to do anything that will harm my provider.
