Consider evidence “missing” in this context if required and material evidence (such
as evidence required by the Listing of Impairments) was not obtained.
Do not develop just to obtain the missing evidence. However, include the missing evidence
in file if received during routine current development.
NOTE: If the individual medically equaled a listing at the time of the prior determination
or decision, do not substitute judgment in applying the error exception. Do not apply
the required and material evidence error for the absence of a particular test required
at the time of the prior determination if the overall evidence supported that the
impairment(s) were at least equal in severity and duration to the criteria of any
listed impairment. If a specified medical finding was missing in a medical equals
decision at the time of the prior determination, the other medical findings of greater
or equal significance relating to the same impairment should be present in the evidence
and explained in the rationale content, see DI 28090.040.
