When a case does not contain complete medical or vocational documentation the SSA
disability program policy requires, the quality reviewer must decide whether to cite
a group I or group II documentation deficiency and return the case for correction
or cite a technical corrective action (TCA). The quality reviewer employs the probability
of reversal (POR) rule to classify medical and vocational documentation deficiencies
as either a group I or group II deficiency, or a TCA.
For a further explanation of the POR rule and classifying documentation deficiencies,
see GN 04440.110.
