Hi Guest! Great question. I know this isn”t exactly the question you asked, but for the two codes you listed: 95851 – range of motion measurements & report, extremity or trunk only 95831 – muscle testing, manual, extremity or trunk only As you see above, both of these codes specify in the description they are for extremity or trunk only, so may not be appropriate for muscle testing of the TMJ”s. If used, I am not aware of a standard modifier that is required. Hope this helps!
