A HI record showing entitlement to Part A and Part B benefits is automatically established
            for all individuals who are on the MBR and,
         
         
            - 
               
                  • 
                     have been entitled to disability benefits for 21 months, or, 
 
 
- 
               
                  • 
                     reach the 3rd month prior to their attainment of age 65. 
 
 
At this time, a HI card is mailed showing an effective date for Part A and Part B
            entitlement. Instructions tell the beneficiary who does not want Part B to:
         
         
            - 
               
                  • 
                     check the appropriate box, 
 
 
- 
               
                  • 
                     sign where indicated, and, 
 
 
- 
               
                  • 
                     return the card to SSA before the effective date shown on the card. 
 
 
When SSA receives a card from a beneficiary who does not want Part B, Part B entitlement
            is removed from the MBR and HI record. A new card showing Part A entitlement only
            is then issued to the beneficiary.
