I just ran across this myself. You need to do the resumption oasis. If it is within that 5 day window then the resumption oasis will generate a 485 for the new cert period. But you will still need to do a resumption order to cover the changes in the current cert period if you are going to be seeing the patient more than once before the new cert starts. Hospital resumption orders only cover the initial resumption visit. Hope this helped!
