The first row is the one used above. A price for one code usually covers the hospital's facility charge only; the doctor, anesthesia, pathology and other services can be billed separately. Ask the hospital for a good faith estimate before a scheduled service: if you pay yourself and the bill comes in $400 or more above the estimate, you can dispute it under the No Surprises Act.
