I don't see documentation on coding of an EEG where all 16 channels were not able to be placed....only 12 channels. I don't think it is a reduced services because the EEG was still completed and I can't find documentation that requires all 16 channels. This particular EEG ran several hours, so I would like to use the 95813 (EEG greater than one hour) but wanted to confirm that there is no # of channel requirement. Your input is appreciated.
