When the review component makes a probability of reversal (POR) determination that
obtaining missing medical or vocational documentation is unlikely to reverse the disability
determination or to change the length of the period of disability, the review component
does not return the case for the missing documentation unless returning the case to
the adjudicating component for another deficiency.
For an explanation of a medical or vocational documentation TCA, see DI 30005.127.
For an explanation of the POR rule and classifying documentation deficiencies, refer
