Before entitlement to DIB can begin, the number holder (NH) must have served a waiting
            period consisting of 5 full calendar months unless the NH meets the condition found
            in DI 10105.075.
         
         This period is long enough to permit most temporary disabilities to be corrected or
            for the individual to show definite signs of probable recovery.
         
         The waiting period begins in the first month, no earlier than 17 months prior to the
            month of filing, (18 months prior to January 1973), in which:
         
         
            - 
               
                  • 
                     The NH has been under a disability for the entire month; i.e., the date of onset is
                        on or before the first day of the month; and
                      
 
 
- 
               
                  • 
                     The NH has DIB insured status. 
 
 
- 
               
                  • 
                     See RS 00301.120 for the effect which the freeze provisions have upon DIB insured status when the
                        date of onset occurs more than 17 months prior to the month of filing, (18 months
                        prior to January 1973).
                      
 
 
Entitlement to the DIB begins with the first full calendar month after the waiting
            period in which all other requirements are met, except where the NH limits the retroactivity
            of the application. For cases involving statutory blindness, see DI 10105.070D.
         
            
               IMPORTANT: See NOTE: in DI 11015.020C.2. regarding a circumstance that does not require disability to exist throughout the
                  month.
