CPT® Code 95836

Electrocorticogram from an implanted brain neurostimulator pulse generator/transmitter, including recording, with interpretation and written report, up to 30 days

An electrocorticogram (ECoG) is a specialized procedure that involves the recording of electrical activity in the brain. This is achieved through the use of electrodes that are strategically placed under the dura mater, which is the outermost layer of the meninges surrounding the brain, allowing for direct contact with the cerebral cortex. The electrodes are connected to a neurostimulator or pulse generator that is implanted above the dura mater, positioned flush with the skull. This setup not only facilitates the continuous monitoring of brain electrical activity but also enables the device to be programmed to deliver electrical stimulation in response to abnormal signals that may indicate seizure activity. The data collected from the ECoG is transmitted wirelessly to a patient data management system, where it can be reviewed and interpreted by healthcare providers. The CPT® Code 95836 specifically reports the comprehensive process of ECoG data collection and recording for a duration of up to 30 days, which includes the interpretation of the data and the provision of a written report by the healthcare provider.
