Is it cheaper to pay cash than use insurance?

Sometimes. Several hospitals publish discounted cash prices below the rates insurers negotiate. If you haven't met your deductible, ask for the self-pay price.

Why do prices differ so much between hospitals?

Each hospital negotiates rates separately with each insurer, and hospitals in the same health system usually share one contract. The same procedure with the same insurer can cost several times more across town.
