What CPT 96133 covers
96133 is reported in addition to 96132 for each further hour of neuropsychological testing evaluation work. It cannot be billed without 96132 for the same evaluation.
Evaluation time stays separate from administration time (96136–96139), and total documented time supports the number of add-on hours reported.
It fits neuropsychological evaluations whose interpretation and reporting extend beyond a single hour.
