2025 CPT code 95829
(Active) Effective Date: N/A Revision Date: N/A Neurology - Electroencephalography (EEG) and related procedures Medicine Services and Procedures > Neurology and Neuromuscular Procedures Feed
Electrocorticogram (ECoG) interpretation and report during surgery; separate procedure.
Modifiers 26 (professional component) and TC (technical component) may be applicable depending on who performed each component of the service. Consult the CPT manual for appropriate modifier use.
Medical necessity for an intraoperative ECoG is established when there's a need for real-time monitoring of brain function during complex neurosurgical procedures to guide surgical resection, minimize neurological deficits, or ensure patient safety.This is often necessary in cases of medically refractory epilepsy, brain tumors located near eloquent areas, or complex vascular malformations.
The physician or qualified healthcare professional is responsible for the interpretation and reporting of the ECoG results.This includes analyzing the recorded brainwave patterns, identifying any abnormalities, and preparing a detailed report to be used by the surgical team.

In simple words: This code covers the doctor's work in analyzing the results of a special brainwave test (ECoG) done during brain surgery.The test uses electrodes placed directly on the brain to record its electrical activity.The doctor interprets the results and writes a report to help with the surgery.
This CPT code reports the interpretation and report of an electrocorticogram (ECoG), also known as intracranial EEG (iEEG), performed as a separate procedure during brain surgery.The ECoG involves recording brain electrical activity from the cerebral cortex using electrodes placed on the brain's surface. The interpretation and report are conducted by a physician or qualified healthcare professional and should be reported in addition to the code for the brain surgery itself.The procedure involves surgically implanting electrodes, analyzing cortical potentials and brain waves, and preparing a comprehensive report detailing the findings.
Example 1: A patient undergoing surgery for medically refractory epilepsy has intracranial electrodes placed to monitor brain activity during resection. Code 95829 is used to bill for the interpretation and report of the electrocorticogram (ECoG) obtained during this procedure., A patient with a brain tumor undergoes surgery for resection.Intraoperative ECoG is used to map eloquent brain areas to minimize neurological deficits. Code 95829 is reported for the interpretation and report of the ECoG, separate from the surgical codes., During a craniotomy for the removal of an arteriovenous malformation (AVM), ECoG is used to monitor brain function and ensure the safety of the procedure. Code 95829 is used to bill for the interpretation and report, distinct from the surgical procedures performed.
Complete operative report detailing the placement of electrodes, duration of recording, and specifics of the surgical procedure.Detailed interpretation of ECoG findings, including location, frequency, amplitude, and clinical significance of any abnormalities.Correlation of ECoG findings with other diagnostic data (e.g., MRI, EEG).Final report summarizing the results and their implications for surgical management.
** The accurate reporting of this code requires careful documentation and appropriate modifier application to ensure correct reimbursement.Always verify coding guidelines and payer-specific requirements to ensure compliance.

- RVU: Information not available in provided text.Refer to the CMS Physician Fee Schedule for the most up-to-date RVU values and reimbursement rates.
- Global Days: Not applicable. This is a separate procedure reported in addition to the surgical procedure. Global days would pertain to the surgical procedure itself.
- Payment Status: Active
- Modifier TC rule: Modifier TC applies to the technical component of the ECoG if the technical component is billed separately from the professional component (interpretation and reporting). This generally means the technical component was provided by a facility or lab, and not by the physician reporting the code 95829.
