Cash price: the hospital's posted discounted price for people paying themselves. Gross charge: its list price before any discount. Insurer rates: the lowest and highest rates it says it negotiated with any insurer. When the file lists a service on several rows, this page shows one (the facility row for the usual setting); the service's own page lists every row.
