95951

Monitoring for up to 24 hours, electroencephalography (EEG) only, or alternatively, and/or simultaneously, video and EEG

CPT code 95951 describes prolonged electroencephalographic (EEG) monitoring, which may include simultaneous video recording, performed for up to 24 hours. This service is utilized for continuous observation and recording of brain electrical activity, often combined with visual documentation of patient behavior. It is typically employed for patients presenting with suspected seizure disorders, unexplained paroxysmal events, or other neurological conditions requiring extended assessment of brain activity to correlate with clinical manifestations. The service encompasses the technical recording component and the professional interpretation of the acquired data.

Clinical Indications

  • Differential diagnosis and characterization of epileptic seizures, distinguishing them from non-epileptic events (e.g., psychogenic non-epileptic seizures, syncope, movement disorders).
  • Localization of seizure onset zones in patients with intractable epilepsy being considered for surgical intervention.
  • Quantification of seizure frequency and assessment of treatment efficacy for anti-seizure medications.
  • Evaluation of unexplained transient neurological symptoms or episodes where an epileptic etiology is suspected.
  • Investigation of paroxysmal sleep disorders when associated epileptic activity is a concern.

Procedure Steps

  1. Patient preparation, including explanation of the procedure, obtaining informed consent, and preparing the scalp.
  2. Application of multiple scalp electrodes according to the international 10-20 system or an expanded montage, ensuring proper impedance.
  3. Connection of electrodes to EEG recording equipment for continuous data acquisition.
  4. Initiation and maintenance of continuous EEG recording for the specified duration, up to 24 hours.
  5. Setup and synchronization of video recording equipment for simultaneous capture of patient behavior (if applicable).
  6. Instruction of patient/caregiver on event logging, where clinical events (e.g., seizures, abnormal movements) are marked in the recording.
  7. Technical monitoring by a qualified technologist for data quality, patient comfort, and safety.
  8. Disconnection of equipment and removal of electrodes upon completion of the monitoring period.
  9. Professional review and interpretation of the entire EEG and video data by a qualified physician, identifying epileptiform discharges, correlating findings with observed events, and generating a comprehensive report.

Coding Guidelines

  • CPT code 95951 includes both the technical and professional components of prolonged EEG-video monitoring for a period of up to 24 hours.
  • This code should be reported once per monitoring session of up to 24 hours. For monitoring sessions exceeding 24 hours, add-on codes (e.g., 95953 for each additional 24 hours) may be utilized.
  • Documentation must clearly state the start and end times of the monitoring, a detailed description of any recorded events, and the comprehensive physician's interpretation and report.
  • The service may include EEG only, or simultaneously, video and EEG. The code is appropriate for either scenario within the 24-hour timeframe.
  • This code should not be reported in conjunction with routine EEG codes (e.g., 95816, 95819) for the same monitoring period.
  • Technical supervision and professional interpretation must be performed by appropriately qualified healthcare professionals, often a neurologist or epileptologist.
