Northwestern Medicine McHenry Hospital
for CT scan of the head · McHenry 60050
One file, 3 locations. These prices come from a file that covers 3 locations — Northwestern Medicine McHenry Hospital, Northwestern Medicine Huntley Hospital and Northwestern Medicine Woodstock Hospital — and the file does not say which of them any price belongs to. Every figure here is that whole file's rather than this one address's. The file's own header names it "Northern Illinois Medical Center DBA Northwestern Medicine McHenry Hospital".
The facilities this file names, exactly as it names them: Northwestern Medicine McHenry Hospital · Northwestern Medicine Huntley Hospital · Northwestern Medicine Woodstock Hospital.
Paying with
You told us you have Aetna. Their rates are marked as yours; the rest are here so you can see the whole file.
The same procedure, at this one hospital, ranges from $682.26 to $3,535. That is not an error, and it is not our arithmetic — it is what the hospital published.
The difference is between insurers and plans. Each negotiates its own rate, so which figure applies to you depends on the card in your wallet.
Your insurer
What Aetna pays here
Every rate this hospital published under a name we recognise as Aetna, cheapest first, grouped by plan and then by the hospital's own line item. Which one is yours depends on your plan and on which line item this hospital bills the service under — the file does not know which card you carry, and does not say which line item it would use.

How complete the paperwork is
What Northwestern Medicine McHenry Hospital published — and what it left out
Federal law tells hospitals what to publish. This score is our reading of how much of that Northwestern Medicine McHenry Hospital actually did publish. It is a measure of their paperwork, not their care. We hold no clinical, safety, or outcome data about any hospital, and nothing here should be read as a comment on the medicine.
0.88/ 1.00
At or above our 0.50 threshold, so this hospital appears in comparisons. A passing score means the file is complete enough to compare, not that it is complete.

Each part is scored from 0 to 1 and multiplied by its weight; the four add up to the total above. Every count in the right-hand column came from the hospital's own file — we did not estimate, impute, or fill a gap on their behalf. Where the file is thin, the score is thin, and the gap belongs to the publisher.
