across 45 hospitals in the Chicago metro. Lowest at UChicago Medicine Adventhealth La Grange, highest at Children's Hospital of Illinois. Both are figures those hospitals published themselves — nothing here is averaged, estimated or rounded.
Every figure above comes from the 45 hospitals listed below and from the single billing code hospitals use for it. Each is that hospital's own published figure. 3 further hospitals publish a figure for this and are withheld below, because what they published is too incomplete to line up fairly against the rest. Those figures still count as peers wherever a comparison appears beside a price, which is why a comparison can be drawn from more hospitals than this page counts — how completely a hospital published says nothing about whether its price belongs in the comparison.
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.
2 published figures excluded: each is at least three orders of magnitude below what its peers publish for the same billing code, which this product treats as a placeholder rather than a real price. Prices that are merely unusual — not placeholders — are never excluded by this filter; ask without plausibleOnly to see them.
Comparisons against other hospitals were computed on 2 November 2026. Each price carries its own fetch date; a comparison is a snapshot of what other hospitals had published when it ran, not a standing fact.

These publish a price for this service, but what they published is too incomplete for us to line up fairly against the rest. They are listed so you know they exist, and each opens to its full prices and the exact parts of its disclosure that are missing — this is about their paperwork, not their care.
