Physician fee in a facility
Read this carefully. The facility figure is the physician fee only. When the same service happens in a hospital outpatient department, the hospital bills its own facility payment on top, and that amount is not in this dataset. So the lower number here does not mean the hospital is the cheaper site. It usually is not. We will not publish a total cost by site of service until we hold the facility payment.
Negotiated prices from published filings, reported only where the sample supports it. For your city, not a statewide average. What plans have agreed to pay, not what a patient is billed. Filings as of July 20, 2026.
Reading it
What this distribution actually says.
The spread
The middle half of this market runs from $129 to $168, a 1.3x difference for the same procedure code in the same city. That gap is between contracts, not between quality.
Against Medicare
The middle price sits at 91% of what Medicare pays for the same service at its Rest Of Missouri locality. Medicare is a fixed reference line most finance teams already have a feel for, which is why we print it beside every figure. It is not a fair price and not what anything should cost.
The expensive end
One in ten filings sits at or above $280. 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
