Official Description

Electroencephalogram (EEG), without video, review of data, technical description by EEG technologist, each increment of 12-26 hours; with intermittent monitoring and maintenance

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 95709 refers to an electroencephalogram (EEG) procedure that involves a long-term continuous recording of brain wave activity without video. This procedure is specifically designed to capture and analyze brain electrical activity over an extended period, ranging from 12 to 26 hours. The recording time is measured from the moment the actual EEG recording begins and continues for the duration of the recording session. The primary purpose of conducting a long-term EEG is to diagnose various neurological conditions, particularly seizure disorders. It helps in identifying the specific type and location of seizures, monitoring the effectiveness of ongoing treatment, and determining the potential for surgical intervention in cases of epilepsy. Additionally, long-term EEGs can be crucial for seriously ill patients, as they allow healthcare providers to screen for new or adverse neurological changes that may arise. The technical aspects of this procedure include the EEG technologist's responsibilities, which encompass uploading the data generated by the EEG equipment, reviewing the raw data, annotating 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 further analysis by a physician or qualified personnel. A comprehensive written report is also generated, documenting the technologist's review of the data and any technical interventions performed during the procedure. This code is specifically used when intermittent monitoring and maintenance are provided, ensuring that the quality of the EEG recording is overseen, with real-time data reviews conducted at least every two hours throughout the entire recording period.

1. Indications

The procedure associated with CPT® Code 95709 is indicated for various neurological assessments and monitoring. The following conditions and situations warrant the use of this extended EEG service:

  • Seizure Disorders The procedure is performed to diagnose specific types and locations of seizures, aiding in the differentiation between seizure disorders and other neurological abnormalities.
  • Monitoring Treatment It is utilized to monitor the effectiveness of current treatment regimens for epilepsy and other seizure-related conditions.
  • Surgical Evaluation The procedure helps determine if a patient’s epilepsy may be amenable to surgical treatment, providing critical data for surgical planning.
  • Neurological Changes Extended EEG services may be conducted on seriously ill patients to screen for new or adverse neurological changes that could impact their treatment and care.

2. Procedure

The procedure for CPT® Code 95709 involves several key steps that ensure the accurate recording and analysis of brain wave activity over an extended period. The following procedural steps are explicitly outlined:

  • Step 1: Setup of EEG Equipment The EEG technician prepares the patient by applying electrodes to the scalp in accordance with standardized placement protocols. This setup is crucial for capturing accurate brain wave data.
  • Step 2: Initiation of Recording Once the electrodes are securely in place, the technician initiates the EEG recording. The time is recorded from this point onward, marking the beginning of the continuous monitoring period.
  • Step 3: Intermittent Monitoring Throughout the recording period, the technician performs intermittent monitoring and maintenance of the EEG equipment. This includes ensuring that the electrodes maintain good contact with the scalp and that the equipment is functioning correctly.
  • Step 4: Data Review The technician conducts real-time data reviews at least every two hours. This involves analyzing the recorded data for any significant events, both patient-generated and machine-detected, and making necessary annotations.
  • Step 5: Data Upload and Archiving After the recording session concludes, the technician uploads the collected data for further analysis. The reviewed data is archived for future reference by the physician or other qualified personnel.
  • Step 6: Documentation A comprehensive written report is generated, documenting the technician's review of the data, any technical interventions performed, and the overall findings from the EEG recording.

3. Post-Procedure

After the completion of the EEG procedure coded as CPT® 95709, several post-procedure considerations are important. The patient may be monitored for any immediate effects or reactions following the EEG. The archived data will be reviewed by a physician or qualified personnel to interpret the findings and determine the next steps in the patient's care. The written report generated by the technician will serve as a critical component of the patient's medical record, providing insights into the brain activity observed during the recording period. Follow-up appointments may be scheduled to discuss the results and any necessary adjustments to treatment plans based on the findings from the EEG.
