If the claimant meets the requirements for entitlement to ESRD, we must determine
                  whether he or she is currently entitled to Medicare under a RLCN. A claimant will
                  have Medicare under an RLCN only if he or she:
               
               
                  - 
                     
                  
- 
                     
                        • 
                           has received a disability benefit from RRB for 24 months. 
 
 
A Medicare record is established if an RRB claimant is age 64 and 8 months or in the
                  20th month of disability.
               
               Secure an MBR and HI/SMI Query Response (HIQR) printouts on the claimant’s own SSN
                  or any other SSN’s involved, such as those indicated in the answer to item 9(c) of
                  the CMS-43 (Application for Health Insurance under Medicare for Individual with Chronic
                  Renal Disease). Review the printouts to determine whether the:
               
               
                  - 
                     
                        • 
                           MBR establishes Medicare entitlement under RRB; 
 
 
- 
                     
                        • 
                           HIQR on the RLCN shows Medicare entitlement for the claimant; or 
 
 
- 
                     
                        • 
                           XCN field of the HIQR on the claimant’s SSN shows a cross reference to an RLCN (six
                              or nine digit number preceded by one, two, or three alpha characters, e.g., WA 123456;
                              A 123456789).
