In case of long-term disability, the duration of the benefit (number of months) cannot be determined in advance when the claim is assessed. In these cases, the benefit is granted for a period of 6 months and the case is reviewed by a senior claims officer every 6 months in order to determine if the benefit should be extended. If the benefit is not extended the client is send a notification about the termination of the benefits. Otherwise, for some benefit renewal cases a simple check is sufficient to determine the benefit entitlement and continue with the process as usual. In other cases, the senior claims officer requires a new medical report, which means that the whole process of obtaining a medical report has to be repeated, except for the letter of authorization signed by the customer.
