Each step is documented — miss one and the claim is denied.
What CPT 96139 covers
96139 is reported in addition to 96138 for each further 30 minutes of technician test administration and scoring. It cannot be billed without 96138 for the same session.
Administration time stays separate from evaluation time (96130–96133), and total documented administration time supports the number of add-on units reported.
It fits longer test batteries administered and scored by a technician that run past the first half hour.
