PHOENIX (AP) _ A new study shows most states provide their employees with health insurance that most private workers would envy _ and Arizona is no exception. 

The study by the Pew Charitable Trusts and the MacArthur Foundation released Tuesday shows the vast majority of Arizona employees are enrolled in a zero-deductible plan that would be considered a ``platinum'' plan under the Affordable Care Act. 

The state plan covers an estimated 94 percent of members' medical costs. That's compared to a typical ``silver'' plan on the federal health insurance exchange that pays just 70 percent and the average private employer-provided plan covers about 80 percent. 

Arizona is among the states that pay the largest share of insurance costs, covering all but 7 percent of the premium for single employees.
