After you begin receiving your retirement pension benefit, if you believe an error was made in calculating the creditable service, you may request an examination of the benefit. Once a review has been done and a determination has been made, you may appeal the determination. However, according to Indiana Administrative Orders and Procedures Act, you can only appeal the determination decision if the appeal is requested within six years after the determination of your creditable service or benefit.
