A sleep-deprived/induced EEG is an EEG recording (with or without video monitoring) performed after: a. an overnight period of sleep deprivation of greater than 4 hours; or b. the administration of a sedative/hypnotic agent prior to the EEG recording for the purposes of sleep induction.
G543 is only eligible for payment if the EEG recording includes all of the following:
a. at least 60 minutes of EEG recording time;
b. a minimum of 16 channels of EEG; and
c. recordings of at least two physiological parameters.
The amount payable for a sleep-deprived/induced EEG that does not meet the above requirements will be reduced to that for a routine EEG fees (i.e. G414 and G415/G418).
Examples of physiological parameters include ECG, respirations, EMG, extra-ocular movements, oxygen saturation, and temperature.
G415 and G418 are not eligible for payment with G543.
EEG services (i.e. G414, G415, G418, G541, G543, G540, G545, G542, G546, G554, G555, or G544) are not eligible for payment with any overnight or daytime sleep study (i.e. J898, J899, J990, J896, J897, J895, J890, J889, J893 or J894).
