A disabled individual between ages 50-65 who is entitled to mother's or father's insurance
            benefits and who files for HI is deemed, for HI purposes only, to have filed as a
            disabled widow(er) upon furnishing proof of disability and meeting all other requirements
            for eligibility to DWB (follow RS 00207.007 ff.). He or she is deemed to have been entitled to these benefits, for HI purposes
            only beginning with the first month for which he or she could have been entitled based
            on deemed filing as a disabled widow(er).
         
          
         Entitlement to Medicare begins with the 25th month of deemed, actual or deemed plus
            actual DWB entitlement.
         
          
         EXCEPTION: Effective July 1, 2001, a disability beneficiary diagnosed with Amyotrophic Lateral
            Sclerosis (ALS), better known as Lou Gehring’s disease will not have to serve the
            24-month Medicare waiting period. The date of entitlement to Medicare is the date
            of entitlement to disability (DOED) benefits or July 1, 2001, whichever is later.
            The Diagnosis code (either primary (DIG) or secondary (SDIG) will be 3350. (See DI 45605.001)
         
          
         Unless declined, entitlement to SMI begins the same month as HI. (See HI 00801.146 ff. for discussion.)
         
          
         “Child-in-care” deductions apply for any month in which a child is not in care. If the claimant wishes
            to become actually entitled as a DWB, he/she must file an SSA-10-BK indicating the
            first month within the retroactive life of the application, entitlement is to begin.
            Usually this will be the first month in which the child is not in care. Failure to
            file the SSA-10-BK will not affect Medicare entitlement. Since the widow(er)'s disability
            and other factors of entitlement will already have been established, no additional
            proofs will be needed.
