If an individual inquiring about HI filing is currently entitled to an RR annuity
            or is being considered in computing an annuity under the SSA guaranty provision, inform
            the individual that shortly RRB should send notification they are automatically entitled
            to HI as a QRRB. However, if an individual could be entitled to an RR annuity or could
            be considered under the SSA guaranty provision but has not filed application with
            RRB, advise them to apply at the servicing RRB district office. Where there is any
            question about an individual's RR status and is not eligible for monthly RSDI benefits,
            obtain an SSA-18F5.
         
         When an application for deemed insured HI is accepted but the individual is eligible
            for HI as a QRRB, the claim must be formally disallowed. The notice of disallowance
            will explain why ineligible for HI with SSA. If the claims file does not indicate
            the individual has filed an application with RRB, advise them to contact the servicing
            RRB district office; they should be instructed to present the disallowance notice
            to that office. Include in the notice a reference to the date the individual filed
            HI application since this date may establish an earlier filing date for the RR benefit.
            If one requested enrollment for SMI, also refer to the date of the filed request.
            The processing center will retain all claims material in the claims folder although
            photocopies of this material may be prepared and sent to RRB upon request.
