She completed IU C&P exams back in Feb 2019 we checked ebenefits today and Noticed she’d been increased to 100% SC MDD P&T ... and an extra special “S” compensation benefit ...my question is how long until she receives back pay?... her effective date is October 8, 2018 to be exact and does she receive back pay in the amount of 100% plus the extra special pay times October 2018 to today March 5, 2019 when her case was completed and closed ?
