Colonoscopy cost in Oregon
Astoria, OR has 47 filings for Diagnostic colonoscopy. We need 100 before we will publish a market figure, so this page shows Oregon 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.

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. Statewide peer distribution, not a single-city sample. 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 $225 to $586, a 2.6x difference for the same procedure code in the same city. That gap is between contracts, not between quality.
Against Medicare
Medicare pays $373 for this service at its Rest Of Oregon locality. We do not turn that into a percentage here, because the price above is Oregon 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 $922. 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
The carriers that filed for this procedure in this market. What each plan has agreed to pay, side by side. These are prices, not bills, so they do not show how often anyone needs it.

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.
