This is from a press release from Blue Cross:

Care Comparison allows [patients] to evaluate total treatment costs as well as quality, safety and accessibility information for dozens of common elective procedures….. Five Blue Cross companies have collaborated to make this tool available to 22 million members throughout the country….. Care Comparison takes unique "packaged" events of care and provides data on all related services and not just the cost of the procedure itself. For example, a package of care for surgery could include charges for the surgeon's services, lab work performed, anesthesia and use of the facility.
