The CPT® Code 95957 refers to the digital analysis of an electroencephalogram (EEG), specifically utilized for tasks such as epileptic spike analysis. An electroencephalogram is a diagnostic test that measures electrical activity in the brain through electrodes placed on the scalp. The digital analysis process involves advanced computational tools that enhance the interpretation of the EEG data. This includes the ability to modify filtering settings, adjust horizontal and vertical display scales, and reformat the montage, which is the arrangement of electrodes used to capture the brain's electrical signals. In this procedure, the EEG is recorded with minimal analog filtering, ensuring that the data captured is as accurate as possible. A single common reference is used for all electrodes, which simplifies the analysis. The technician employs a computer to reformat the EEG recording into various montages, either referential or bipolar, depending on the clinical needs. This digital reformatting is crucial as it allows for the application of different filters to segments of the EEG that exhibit abnormalities, enabling a more detailed examination of the brain's electrical activity. The ability to reformat the EEG multiple times with different montages and filters enhances the visualization of abnormalities, which is essential for distinguishing between epileptiform brain wave patterns—indicative of epilepsy—and nonepileptiform patterns. After the digital analysis is completed, the physician reviews both the original and the digitally reformatted EEGs, leading to a comprehensive evaluation. The findings from this analysis are then documented in a written report, which is critical for guiding further clinical decisions and treatment options.

The digital analysis of an electroencephalogram (EEG) using CPT® Code 95957 is indicated for various clinical scenarios, particularly when there is a need to assess and differentiate brain wave patterns. The following conditions may warrant this procedure:
The procedure for the digital analysis of an EEG involves several key steps that ensure accurate and detailed evaluation of the brain's electrical activity. The following outlines the procedural steps:
Post-procedure care following the digital analysis of an EEG typically involves the physician discussing the findings with the patient. The written report generated from the analysis may include recommendations for further testing or treatment options based on the results. Patients may be advised on any necessary follow-up appointments or additional evaluations needed to address their neurological health. It is important for the physician to ensure that the patient understands the implications of the findings and the next steps in their care plan.

| 26 | Professional component: certain procedures are a combination of a physician or other qualified health care professional component and a technical component. when the physician or other qualified health care professional component is reported separately, the service may be identified by adding modifier 26 to the usual procedure number. | 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. | XU | Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service | GV | Attending physician not employed or paid under arrangement by the patient's hospice provider | TC | Technical component; under certain circumstances, a charge may be made for the technical component alone; under those circumstances the technical component charge is identified by adding modifier 'tc' to the usual procedure number; technical component charges are institutional charges and not billed separately by physicians; however, portable x-ray suppliers only bill for technical component and should utilize modifier tc; the charge data from portable x-ray suppliers will then be used to build customary and prevailing profiles | GC | This service has been performed in part by a resident under the direction of a teaching physician | KX | Requirements specified in the medical policy have been met | GW | Service not related to the hospice patient's terminal condition | 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. | GA | Waiver of liability statement issued as required by payer policy, individual case | GY | Item or service statutorily excluded, does not meet the definition of any medicare benefit or, for non-medicare insurers, is not a contract benefit | Q6 | Service furnished under a fee-for-time compensation arrangement by a substitute physician or by a substitute physical therapist furnishing outpatient physical therapy services in a health professional shortage area, a medically underserved area, or a rural area | XE | Separate encounter, a service that is distinct because it occurred during a separate encounter | XP | Separate practitioner, a service that is distinct because it was performed by a different practitioner | XS | Separate structure, a service that is distinct because it was performed on a separate organ/structure |
