Some drug benefit changes went into effect July first and now one legislator wants to know more about those changes. House Speaker Rick Thompson is concerned because he is hearing from staff members and consitiuents costs have dramatically increased. He's asking the head of the state Public Employees Insurance Agency for answers. Under the former plan, participants were charged $50 co-pays for certain brand-name prescriptions; the new plan requires them to pay 75 percent of the cost for those drugs. He's especially concerned about those with chronic conditions who may cut or stop treatment because of the costs.
