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.

The electrocorticogram (ECoG) procedure is indicated for various clinical scenarios where monitoring of brain electrical activity is essential. The following conditions may warrant the use of this procedure:
The procedure for conducting an electrocorticogram (ECoG) involves several critical steps to ensure accurate data collection and interpretation. The following outlines the procedural steps:
Post-procedure care for patients who have undergone an electrocorticogram (ECoG) includes monitoring for any potential complications related to the electrode placement and the implanted device. Patients may be advised to avoid certain activities that could risk dislodging the electrodes or causing injury to the surgical site. Follow-up appointments are typically scheduled to review the findings from the ECoG and to discuss any necessary treatment plans based on the results. Additionally, healthcare providers may provide instructions on managing the surgical site and recognizing signs of infection or other complications.

| 59 | Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25. | 95 | Synchronous telemedicine service rendered via a real-time interactive audio and video telecommunications system: synchronous telemedicine service is defined as a real-time interaction between a physician or other qualified health care professional and a patient who is located at a distant site from the physician or other qualified health care professional. the totality of the communication of information exchanged between the physician or other qualified health care professional and the patient during the course of the synchronous telemedicine service must be of an amount and nature that would be sufficient to meet the key components and/or requirements of the same service when rendered via a face-to-face interaction. modifier 95 may only be appended to the services listed in appendix p. appendix p is the list of cpt codes for services that are typically performed face-to-face, but may be rendered via a real-time (synchronous) interactive audio and video telecommunications system. | CR | Catastrophe/disaster related | GC | This service has been performed in part by a resident under the direction of a teaching physician | Q1 | Routine clinical service provided in a clinical research study that is in an approved clinical research study | XU | Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service |
