Polysomnography is distinguished from sleep studies by the inclusion of sleep staging that includes a 1‑to 4- lead electroencephalogram (EEG), electro-oculogram (EOG), and a limb or submental electromyogram (EMG).
For a sleep study to be reported as a polysomnography, sleep must be recorded and staged. Use the following procedure codes to bill for polysomnography studies: 95782, 95783, 95808, 95810, and 95811.
Documentation of the polysomnography testing must be maintained in the client’s medical record at the sleep facility and include approximately 1,000 pages or the electronically-stored equivalent of data during a single nighttime recording. Each record must be for sleep-wake states and stages, cardiac arrhythmias, respiratory events, motor activity, oxygen desaturations, and behavioral observations.
Interpretation and treatment recommendations must be completed by a sleep specialist. The physician’s professional interpretation and report must include inspection of the entire recording, examination of the technologist’s analysis and observations, and integration of the information gathered from all physiological systems. Documentation of the interpretation must be maintained in the sleep facility and by the interpreting physician.
