The DDS will determine whether an attempt should be made to create a replacement folder,
and what portions of that missing file are relevant to the most recent favorable determination/decision
(e.g., work history, medical evidence from treating sources, school records, and the
results of consultative examinations). The DDS will consider the potential availability
of old records in light of their age, and whether the source(s) of the evidence is/are
still in operation, and whether reconstruction, in the form of a replacement folder,
is needed. Regardless of the DDS decision to pursue reconstruction, SSA will not find that the individual has medically improved based solely on the original
medical evidence being lost, but SSA can redevelop that missing medical evidence and
make a MIRS determination.
