I would recommend referencing Appendix J of the CPT code book which provides a breakdown of motor and sensory nerves. Based on review of the report, I am counting 4 sensory (median-D1, median-D4, radial-D1, ulnar-D4) + 3 motor (median-APB, ulnar-APB, ulnar-ADM) = 7 studies (95910). On the motor nerves, you would not count the 2nd point stim on the median-APB nor the 2nd and 3rd stims in the ulnar-ADM. Your 95886 is correct.
