Great TotalHealth to Great TotalCare (Autochange?)

I have received a notification from GE saying that the Great TotalHealth will be automatically changed to Great TotalCare and that from the new renewal date onwards, my deductibles and co-insurance will now be subjected to 5% co-payment. I used to pay for riders that cover this option but it seems like there is not such option that will cover 100% of deductibles even though I am a existing since Y2015. It seems like this change is coming out from MOH. I will like to know if other insurers such as Prudential, AIA, AXA etc are also likewise having such changes? Is there anyway to continue with the old plans?
