EMG and Nerve Conduction Studies

Melissa Posted Sat 25th of January, 2020 12:11:24 PM
Hi, I am new to Neurology coding; can you advise how I would code the following dictation: "Bilateral EMG/NCS ; temp for NCS maintained at 33 degrees C. I have personally performed the NCS along with the technologist. Bilateral sural and superficial peroneal SNAPS are unobtainable; bilateral common peroneal at EDB, bilateral tibial and right common peroneal at TA have slow conduction velocity. In addition, right common peroneal proximal conduction velocity across fibular head is slower than distal segment instead of being faster and 29.9 m/s value crosses the threshold of being demyelinating range ( 30 and below ) Only the left common peroneal at TA has normal conduction velocity. bilateral tibial and common peroneal at TA have low amplitudes as well; H waves are absent on either side. Needle examination of selected myotomes of L2-S1 along with lumbar paraspinals were tested. There is finding of chronic denervation in the right TA, Gastroc and PL and left VL and also in paraspinals"

Hello Melissa,

Thank you for your question.


As per the above presented documentation, it’s unclear to distinguish the number of muscles and nerve being tested through EMG and NCS respectively.


Kindly provide us with some more details of the nerve(s) and muscle(s) being tested via each method on the same day. Based upon the same, we’ll be able to provide you with the most appropriate CPT® code (s).


Note: As per CPT® guidelines, use 95885, 95886, and 95887 for EMG services when nerve conduction studies (95907-95913) are performed in conjunction with EMG on the same day.
