Monitoring for localization of cerebral seizure focus by cable or radio, 16 or more channel telemetry, electroencephalographic (EEG) recording and interpretation, each 24 hours, attended by a technologist or nurse

An electroencephalogram (EEG) is a diagnostic procedure that measures and records the electrical activity of the brain. This specific procedure, identified by CPT® Code 95956, involves monitoring for the localization of cerebral seizure focus using advanced telemetry techniques. The EEG captures electrical current potentials generated by nerve cells in the brain, which are essential for understanding brain function and diagnosing conditions such as epilepsy. The procedure utilizes either cable or radio telemetry to transmit the recorded electrical signals from the EEG leads, which are strategically placed on the scalp, to a digitized receiver. This receiver processes the data, allowing for real-time monitoring and interpretation of the EEG recordings. The entire process is attended by a qualified technologist or nurse, ensuring that the recordings are accurately captured and monitored throughout the duration of the test. The EEG is conducted over a specified period, typically 24 hours, during which the technologist or nurse oversees the collection of data. After the monitoring period, the physician reviews the recorded data and generates a comprehensive report detailing the findings, which is crucial for diagnosing and managing seizure disorders.
