The Stieberger settlement agreement provides special development and payment rules
            for use in reopenings. How these special rules affect title II cases is discussed
            below. A complete discussion of the special  Stieberger rules may be found in DI 12586.020 - DI 12586.090.
         
         It is not usually necessary for the DDS to develop disability for the entire period.
            Rather, the settlement agreement permits the DDS, subject to certain exceptions explained
            below, to develop for a limited period, usually beginning 48 months prior to SSA's
            receipt of the request for review. (See B. for instructions on computing the  Stieberger DEVELOPMENT PERIOD).
         
         The Stieberger PAYMENT PERIOD may also be limited, but usually begins earlier than
            the DEVELOPMENT PERIOD. (See DI 42586.065 for instructions on computing the title II PAYMENT PERIOD).
         
         The FO computes the DEVELOPMENT PERIOD and PAYMENT PERIOD prior to sending a case
            to the DDS.
