The 1965 amendments removed the requirement that the claimant’s condition is disabling
            at the time the claimant files the application, and allowed for a closed period of
            disability if the disability ceased no earlier than 12 months before the month of
            the application file date.
         
         The 1967 amendments provided for the extension of the 12-month requirement to 36 months
            in situations where the claimant was physically or mentally incapable of filing the
            claim in the 12-month period after his disability ceased. Since the number holder
            (NH) was not under a disability during the 12-month retroactivity limitation for monthly
            benefits, a denial of the disability insurance benefits (DIB) claim is appropriate.
            Under this section, a closed period of disability freeze might be established.
         
         Disability Determination Services (DDS) jurisdiction cases referred to the examiner
            where the DDS does not determine whether the claimant’s failure to file a timely application
            (within 12 months of disability cessation) was due to physical or mental incapacity
            the Disability Examiner /Disability Processing Specialist (DE/DPS) will make the determination.
         
         The field office may route the case directly to the Office of Disability Operations/Processing
            Center-Disability Processing Branch (ODO/PC-DPB) in which the claimant filed after
            12 months but within 36 months of the month of the alleged cessation.
         
         If it is determined that the claimant's failure to file a timely application was not
            due to physical or mental incapacity, prepare a determination of denial and personalized
            letter to the claimant.
         
         If it is determined that the claimant's failure to file a timely application was due
            to physical or mental incapacity, route the case to the DDS using Form SSA-847 (SSA
            Request for Case Action), for preparation of the determination.
         
         If the case is electronic, the PCs DE/DPS input a “No Determination” decision code
            in MIDAS using the instructions in DI 81020.127 and route the claim to the appropriate DDS, using the instructions in Electronic
            Case Routing before Final Determination in DI 81020.125.
