The Bluegrass State is trying to make health insurance more transparent for big employers.

Kentucky has a new law that will require insurers to give specific premium, enrollment and utilization data to any sponsor of a large group with 51 or more enrolled employees that asks for the data, according to regulators in the Kentucky Office of Insurance.

An insurer must provide a large-group utilization report within 30 calendar days after receiving a written request, but it need not produce the reports more than twice annually, regulators write in Kentucky Bulletin 2007-02, which describes several new insurance laws adopted recently by the Kentucky General Assembly.
