Reading it
What this distribution actually says.
The spread
The middle half of this market runs from $1,411 to $2,269, a 1.6x 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 156% of what Medicare pays for the same service at its San Luis Obispo-Paso Robles 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 $3,620. 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.
