Official Description

Electroencephalogram (EEG), without video, review of data, technical description by EEG technologist, each increment of 12-26 hours; unmonitored

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 95708 refers to the technical aspects of an electroencephalogram (EEG) performed without video monitoring, specifically focusing on the review of data collected over an extended period of time, which ranges from 12 to 26 hours. This procedure is essential for capturing and analyzing brain wave activity, particularly in patients who may be experiencing seizure disorders or other neurological conditions. The EEG is a non-invasive test that records electrical activity in the brain, and the long-term monitoring allows for a comprehensive assessment of brain function over an extended duration. The time counted for this procedure begins when the actual recording starts and continues for the entire duration of the recording session. The primary purpose of conducting a long-term EEG without video is to diagnose specific types and locations of seizures, evaluate the effectiveness of current treatments, and differentiate between seizure disorders and other neurological abnormalities. Additionally, this procedure can be crucial for identifying new adverse neurological changes in seriously ill patients. The technical components of this service include the EEG technologist's responsibilities, which encompass uploading the data generated by the EEG equipment, reviewing the raw data with necessary annotations, and editing recognized events—both those generated by the patient and those detected by the machine. Furthermore, the technologist is responsible for storing or archiving the reviewed data for future analysis by a physician or qualified personnel, as well as preparing a written report that documents the review process and any technical interventions that were performed during the recording. This code is specifically used for unmonitored technician services, distinguishing it from other codes that involve varying levels of monitoring and oversight during the EEG recording process.

1. Indications

The procedure associated with CPT® Code 95708 is indicated for various clinical scenarios where long-term monitoring of brain activity is necessary. The following conditions and symptoms may warrant the use of this procedure:

  • Seizure Disorders - To diagnose specific types and locations of seizures, aiding in the determination of appropriate treatment options.
  • Monitoring Treatment - To evaluate the effectiveness of current treatment regimens for epilepsy or other seizure-related conditions.
  • Distinguishing Conditions - To differentiate between seizure disorders and other neurological abnormalities that may present with similar symptoms.
  • Surgical Evaluation - To assess whether a patient’s epilepsy may be amenable to surgical intervention based on the data collected.
  • Neurological Changes - To screen for new, adverse neurological changes in seriously ill patients, providing critical information for ongoing care.

2. Procedure

The procedure for CPT® Code 95708 involves several key steps that ensure the accurate collection and analysis of EEG data over an extended period. The following procedural steps are outlined:

  • Step 1: Setup and Initiation - The EEG technologist prepares the patient for the EEG by placing electrodes on the scalp according to standardized protocols. Once the electrodes are securely attached, the technologist initiates the recording process, marking the start time for the duration of the EEG.
  • Step 2: Continuous Recording - The EEG records brain wave activity continuously for a period of 12 to 26 hours. During this time, the technologist monitors the equipment to ensure proper functioning and data collection, although this specific code does not involve real-time monitoring of the patient.
  • Step 3: Data Upload and Review - After the recording period concludes, the technologist uploads the collected data from the EEG equipment. This data is then reviewed for quality and accuracy, with the technologist annotating any significant events that occurred during the recording, including both patient-generated and machine-detected activities.
  • Step 4: Data Archiving - The reviewed data is stored or archived for further analysis by a physician or other qualified personnel. This step is crucial for ensuring that the data is accessible for future reference and evaluation.
  • Step 5: Report Generation - Finally, the technologist prepares a written report documenting the review of the EEG data, including any technical interventions that were performed. This report serves as a critical component of the patient's medical record and is essential for subsequent clinical decision-making.

3. Post-Procedure

After the completion of the EEG procedure coded as CPT® 95708, the patient may be monitored for any immediate effects of the test, although no specific post-procedure care is typically required for this unmonitored service. The technologist's report, which includes the reviewed data and any annotations, is forwarded to the physician for interpretation. The physician will analyze the findings and determine the next steps in the patient's care, which may include further diagnostic testing, adjustments to treatment plans, or referrals to specialists based on the results of the EEG. It is important for the healthcare team to communicate any significant findings to the patient and discuss potential implications for their ongoing management.

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.
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
GC This service has been performed in part by a resident under the direction of a teaching physician
