Negotiated rates published

$1.49 – $8,500

across 48 hospitals in the Chicago metro. Lowest at MacNeal Hospital Gottlieb Community Health Services Corporation, highest at Ann & Robert H. Lurie Children's Hospital of Chicago. Both are figures those hospitals published themselves — nothing here is averaged, estimated or rounded.

Every figure above comes from the 48 hospitals listed below and from the single billing code hospitals use for it. Each is that hospital's own published figure. 3 other hospitals publish only a formula for this — a percentage of some other number rather than a price — so they are not in these figures at all.

Written by an AI model (lmstudio google/gemma-4-26b-a4b) on 21 August 2026, from the published figures on this page. Every figure in it is one of theirs.

48 hospitals publish a negotiated rate for Kidney function test in an outpatient setting, and the dearest of those figures is $80.22, though the cheapest sits far enough below the middle of what the others publish that this summary does not state it as the bottom of a range. 16 of those hospitals published a figure unlike what its peers published for the same thing. 18 hospitals publish a negotiated rate for Kidney function test in an inpatient setting, and their figures run from $2.44 to $525.62, with 7 of those hospitals publishing a figure unlike what its peers published for the same thing. 4 hospitals publish only a formula for Kidney function test — a percentage of some other number rather than a price — so they are in none of these figures.

48 hospitals · 1665 published rates Cheapest first

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.

Not one hospital — 3 facilities in one file This is not a single hospital. Endeavor Health Clinical Operations publishes one price file for 3 of its facilities — Endeavor Health Evanston Hospital, Endeavor Health Glenbrook Hospital and Endeavor Health Skokie Hospital — and names all 3 without saying which of them any price belongs to, so these figures cannot be split between them. The address we show for it — 2650 Ridge Ave, Evanston, IL 60201 — is the one this file gives for Endeavor Health Evanston Hospital, one of the 3, and not an address of its own. We list it under "Endeavor Health Skokie Hospital", the name that publisher's own index of its files gave this one; the file's own header calls it "Endeavor Health Clinical Operations". The prices are served in full, exactly as published; what no file here can tell you is which of the 3 you would be charged at.
