Why do hospital bed counts differ between lists?

Lists count different beds. This one uses staffed beds: beds set up and staffed for patients during the cost report year, as each hospital reports them to Medicare. Licensed beds, the most a state allows, are usually higher, and some lists add up every campus or every hospital in a health system, so the same hospital can rank differently from one list to the next.
