A Plan shall provide a grievance form for any enrollee, employer, insurer, insured or provider who wishes to file a written grievance. The form shall include information about the grievance system to help the person in completing and filing the form. Nothing in OAC 310:657 prevents a Plan from using other methods, such as a toll-free telephone line, to correct problems before the employee files a written grievance.
