My mum is on long-term outpatient Specialist care at TTSH and there are scheduled appointments like quarterly or bi-monthly. The next appointment is always pre-scheduled in advance. Todate for the last few years we have been able to keep to appointment dates, but only this time, a re-scheduling had to be made. I requested the change more than a week prior to that appointment, so that gives them sufficient time for whatever is needed. But I was surprised when I was told that they are charging $10 admin fee for the change.
