The Centers for Medicare & Medicaid Services (CMS) collects Supplementary Medical
                  Insurance based on ESRD(R-SMI) premiums in the same manner as other SMI premiums.
               
               R-SMI coverage ordinarily begins with the first month of hospital insurance based
                  on ESRD (R-HI). If the beneficiary’s R-HI is retroactive, the R-SMI can also be retroactive
                  causing difficulty in paying the retroactive R-SMI premiums. The equitable relief
                  provisions apply to premium arrearage situations of six or more months of retroactive
                  R-SMI coverage. The Social Security Administration (SSA) informs the beneficiary,
                  or his or her responsible representative, when there appears to be a six or more month
                  premium arrearage because he or she has an option of when the R-SMI begins. The beneficiary
                  has the following options for the R-SMI effective date:
               
               
                  - 
                     
                        •
                        
                           first month of R-HI if the enrollee elects and is able to pay all the past-due premiums,
                           
                         
                      
                   
                  - 
                     
                        •
                        
                           the month of filing for R-HI/R-SMI, or
                           
                         
                      
                   
                  - 
                     
                  
 
               
               If any of the above situations apply, the equitable relief item on the HIHI screen
                  in MCS must be “Y”.
               
               If the file does not reflect a clear election for the R-SMI effective date when retroactive
                  coverage applies, the SMI coverage is prospective (i.e., coverage begins with the
                  month of processing) and the claimant is notified of his/her right to have earlier
                  coverage.
               
               SSA can amend the SMI award to give retroactive coverage if we receive a timely request
                  and payment.
