A range means this hospital published different amounts on matching machine-readable-file lines. We show the lowest–highest posted amount because we cannot tell from the published file which line would apply to a particular visit.
As a Critical Access Hospital, Medicare pays this facility about 101% of its own costs. The × Medicare column compares the cash price against that cost-based benchmark, not a standard rate.
