Question: How should I code for 95920 during spinal surgeries?
Answer: If during a spinal surgery, the only modality you are using is screw stimulation, you should report 95920 only for the time spent to interpret to collect this data. You should not report 95920 for the duration of the surgical procedure (i.e. skin incision to skin closure). You can report 2 units of CPT 95870(Needle EMG; limited study of muscles in one extremity or non-limb (axial) muscles (unilateral or bilateral), other then thoracic paraspinal, cranial nerve supplied muscles or sphincter) if performed in each leg. However, if five or more muscles are stimulated, then CPT 95861 (Needle electromyogrphy;2 extremities with or without related paraspinal areas) should be reported.
