When collateral estoppel applies, the DDS may, with some exceptions, make the determination
without medical consultant (MC) or psychological consultant (PC) review. For additional
information, see DI 24501.001B.2 and DI 24501.002A.
When the potential onset date (POD) in the new claim is earlier than the EOD in the
prior favorable determination or decision, the DDS must complete development for the
period not previously adjudicated to determine the established onset date (EOD). This
will require adjudication in the usual manner for the earlier period, including MC
or PC review and signature. For information on medical evaluation, see DI 24501.002.
When a diary was never scheduled on the prior favorable determination or decision,
the diary is due, or the diary is past due, or will be due within 3 months, set a
MIE diary on the new claim to mature in 1 year unless the diary was MIP or MINE. When
the diary on the prior determination or decision was MIP or MINE, and no CDR issue
is raised, set a MIP or a MINE diary based on the individual case facts. For more
information on diaries, see DI 26525.000.
Enter the primary and secondary impairment codes used in the adopted prior favorable
determination or decision in Items 16A and 16B of the SSA-831. For more information
on completing Item 16A and 16B, see DI 26510.015.
Enter the regulation basis code “CE” for title II claims and “ACE” for title XVI claims
in Item 22 of the SSA-831. For more information on completing Item 22, see DI 26510.045.
NOTE: Because eCAT functionality requires an MC/PC signature, the DDS may process collateral
estoppel determinations that do not require an MC/PC signature outside of eCAT.
