A previously entitled beneficiary may become eligible for EXR if their medical condition
            no longer permits them to perform substantial gainful activity (SGA) within 60 months
            of their prior termination. If an individual does not request EXR within the consecutive
            60-month period beginning with the month that entitlement or eligibility terminated,
            the individual can ask for an extension of time to request reinstatement. An individual's
            request for an extension of time must be in writing and must give the reason(s) why
            the EXR request was not made within the stated time period. If the reason(s) shows
            that the individual has good cause for missing the deadline, then an extension of
            time for requesting EXR can be given. Note: Granting good cause for late filing has no effect on the 12-month maximum retroactivity
            for reinstatement. In the example below, the earliest possible EXR month of entitlement
            would be July 2021, even though SGA ended in 2020. For more information on examples
            of good cause requests see, GN 03101.020 and SI 04005.015.
         
         EXAMPLE:  In July 2022, the field office (FO) makes a work CDR determination which terminates
            an individual’s entitlement back to 2016 (date of benefit cessation (DBC) of 04/16).
            The individual has not engaged in SGA since 2020. The individual files for EXR in
            July 2022. As the individual was not notified that their benefits were terminated
            until July 2022, the FO establishes good cause for the late filing and processes the
            EXR request with a filing date of July 2022.
