New data released by the nation’s largest nurses’ organization reveals that Nevada hospitals are among the most costly in the nation, helping fuel a growing scandal of high hospital charges and costs. Nevada ranks fourth nationally in how high it sets its charges over its costs, with a statewide average charge of 448 percent as a percent of total costs. In other words, the average Nevada hospital charges $448 for every $100 of its total costs. That’s well above the national average of 331 percent.
