Abdominal CT cost in Illinois
No plan has filed CT abdomen and pelvis, with contrast in Sterling, IL in a form we can read, so this page shows Illinois instead and says so. These are the rates plans published under federal law. Not billed charges, and nothing here is scaled, adjusted or estimated to stand in for the market we do not hold.

Reading it
What this distribution actually says.
The spread
The middle half of this market runs from $221 to $601, a 2.7x difference for the same procedure code in the same city. That gap is between contracts, not between quality.
Against Medicare
Medicare pays $282 for this service at its Rest Of Illinois locality. We do not turn that into a percentage here, because the price above is Illinois and that Medicare figure is one locality inside it. Two different maps do not divide.
The expensive end
One in ten filings sits at or above $1,033. If a plan's network is weighted toward that end, the difference does not show up in a premium quote. It shows up in the claims.
How wide the data runs

Every figure on this page carries its source, its scope and the date the corpus was built, so it survives being forwarded to someone who was not in the meeting.
