across 16 hospitals in the Chicago metro. Lowest at Louis A. Weiss Memorial Hospital, highest at Central DuPage Hospital. Both are figures those hospitals published themselves — nothing here is averaged, estimated or rounded.

Every figure above comes from the 16 hospitals listed below and from the single billing code hospitals use for it. Each is that hospital's own published figure.

Sorted cheapest first. A published figure that behaves like a placeholder rather than a real price — one cent, or a figure orders of magnitude below what other hospitals publish for the same billing code — never leads this order. It stays listed, after every other figure, ordered by its own amount among the others like it.
