As we all probably know, EEG leads are typically used during a sleep study to measure body and brain activity to assist in diagnosing sleep disorders. One of our Neurologists is not only an Epileptologist, but he is also boarded in sleep medicine. He will when indicated, order a sleep study with "seizure montage". Additional electrodes are placed beyond the 'norm'. The physician is not only looking to diagnose sleep disorders but also suspects seizures and is looking for data related to the same. It will take the doctor three times as long to interpret. I know we cannot bill a 'standard' EEG with a sleep study, but does anyone have any experience/information regarding regulations and reimbursement related to a sleep study with seizure montage?
