Neurology & Pain Management Coding Alert

The answer to the reader question "Use 95951 for 'up to' 24 Hours" (Neurology Coding Alert, October 2003, page 79) contained an error.
 
As printed, the answer stated, "You do not need to append modifier -52 (Reduced services) for fewer than 15 hours of [EEG] monitoring, although you should append the modifier for 15 hours or less."
 
The answer should have stated that you do not need to append modifier -52 if you are reporting 15 or more hours (up to 24 hours) of electroencephalographic monitoring (95951, Monitoring for localization of cerebral seizure focus by cable or radio, 16 or more channel telemetry, combined electroencephalographic [EEG] and video recording and interpretation [e.g., for presurgical localization], each 24 hours), but that you should append modifier -52 when reporting fewer than 15 hours of monitoring, according to the advice of the American Clinical Neurophysiology Society, which many insurers follow.
