Has anyone heard of practices purposely unbundling surgical charges just to track statistical data? Our practice may be interested in doing this so as to be able to negotiate better rates with the insurance companies. I am extremely uneasy with this practice. Can anyone point me in the direction of some kind of documentation to make my case? They don't seem to want to listen that even if they expect to get denied and write off the charge, it is still wrong to bill for the service.
