For context: Our providers regularly do Brainscopes (EEGs 95816 and Neuro Psych testing 96132) on patients who have had auto accidents or other reasons why a patient might have gotten a concussion. On one particular patient, the EEG portion was attempted twice, but the MA couldn't get any results because the patient couldn't relax due to pain. I had coded the EEG with modifier 52 due to that and received this rejection by our biller. Does anybody know what that rejection means and how it could be fixed?
