What these three numbers mean
Self-pay price is what the hospital says it charges someone paying directly. It is the number to ask for by name. List price is the undiscounted charge almost nobody pays. Insurers pay is the range of procedure-specific negotiated rates in the file — useful mainly to see whether the self-pay price is above or below what insurers get.
Some hospitals attach one flat rate to nearly their whole price list. Those are excluded here, because a number identical for a colonoscopy and a blood test says nothing about either. More on that →
