Can you tell me more about hyperventilation and/or photic stimulation in relation to codes 95816 and 95819?
According to information in the American Medical Association (AMA) CPT® Assistant Newsletter (July 2000), hyperventilation and/or photic stimulation are not a mandatory part of EEG testing in the case of codes 95816 and 95819. They are performed only when medically necessary and not contraindicated by the patient’s other medical circumstances. It is not appropriate to report these services separately, as they are considered to be an integral part of the EEG service performed. The absence of hyperventilation and/or photic stimulation does not preclude the use of codes 95816 and 95819.
