Showing every price this hospital published. Say how you are paying and we will mark the one that is yours.

Two things are happening. Rates differ between insurers and plans, as you would expect — and the same plan also appears more than once at different prices. Each rate below is shown with the hospital's own line-item description, so you can read how its file labels them. The file does not say which one you would be billed under, so we show every figure rather than pick one.
Rate by insurer, plan and line item
What each insurer pays
Sorted cheapest first, grouped by plan and then by the hospital's own line item. Plan names and line items are written exactly as the hospital wrote them. A plan that carries more than one price gets one row per price; line items the hospital priced the same are listed together once, because the file gives no reason to show one price as several.
