CPT 95967: MEG Evoked Brain Activity, Additional Functional Modality

CPT code 95967 designates an add-on magnetoencephalography (MEG) procedure in which the clinician records and analyzes evoked brain magnetic activity for an additional functional modality such as language, sensory, or motor testing. Nationally, this code matters because MEG add-on testing supports presurgical planning, functional brain mapping, and advanced neurologic assessment where noninvasive localization of cortical function influences clinical decisions. Payers often evaluate coverage based on clinical indication, setting, and documentation of the additional modality testing.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical role of this add-on MEG modality, typical sites of service, and common billing modifiers associated with advanced neurodiagnostic procedures. The publication also summarizes benchmarking considerations, payer policy themes relevant to MEG add-ons, and practical coding context to support accurate claim submission. Data not available in the input is noted where specific payer policy details, taxonomies, ICD-10 pairings, or related codes would normally be listed.

Billing Code Overview

CPT code 95967 is an add-on neurodiagnostic procedure that records and analyzes evoked brain magnetic activity using magnetoencephalography (MEG). In this procedure, the provider assesses an additional brain functional modality — for example, language, sensory, or motor function — during the MEG study to localize and characterize brain activity associated with those functions.

Service type: Evoked brain magnetic activity testing (magnetoencephalography), additional modality added to primary MEG study

Typical site of service: Hospital outpatient department or dedicated neurophysiology/advanced neuroimaging center

Clinical & Coding Specifications

Clinical Context

A 34-year-old right-handed patient with medically refractory focal epilepsy is referred for pre-surgical functional brain mapping. The neurology team orders magnetoencephalography (MEG) with additional language and motor task paradigms to localize eloquent cortex and to delineate the epileptogenic zone prior to epilepsy surgery. The patient arrives to the outpatient neuroimaging center on the scheduled day, completes safety screening for ferromagnetic implants, and is positioned comfortably under the MEG sensor array. Baseline resting-state recordings are obtained, followed by task-based stimulation: a language paradigm (receptive and expressive naming tasks) and a motor paradigm (finger tapping). Continuous MEG signals are recorded, event-related responses are marked, and simultaneous video-EEG (if available) is time-synced. The interpreting neurophysiologist reviews sensor-space and source-space analyses, annotates evoked responses for the additional brain modality (language or motor), and produces a clinical report describing localization relative to anatomical MRI. The report is used by the multidisciplinary team (neurology, neurosurgery, neuroradiology) to inform surgical planning or further management.

Coding Specifications

Modifier	Description	When to Use
`26`	Professional component	When billing only the physician interpretation portion of the MEG study.
`TC`	Technical component	When billing only facility/technical services for MEG equipment and technologist.
`59`	Distinct procedural service	When MEG add-on is performed separate and independent from another procedure on the same day and not ordinarily bundled.
`62`	Two surgeons	When two surgeons from different specialties are jointly performing related surgical procedures and MEG guidance is part of the surgical episode (rare for MEG alone).
`78`	Return to operating room after prior procedure	Applicable if MEG-guided repeat operative intervention occurs during the postoperative global period (procedural episode context).
`80`	Assistant surgeon	When an assistant surgeon participates in a procedure that used MEG for intraoperative guidance and assistant billing is appropriate.
`82`	Assistant surgeon (when qualified resident unavailable)	Alternate assistant surgeon reporting when a qualified resident is not available.
`22`	Increased procedural services	When the MEG study required substantially greater work, time, or complexity than typical (documented in report).
`52`	Reduced services	When the MEG study is partially reduced or not completed for clinical reasons (document reason).
`53`	Discontinued procedure	When the MEG study is started but terminated due to patient intolerance or safety concerns.
`59`	Distinct procedural service	When an add-on MEG modality is distinct from another billed neurophysiology test on same day (ensure correct use with NCCI guidance).
`23`	Unusual anesthesia	When general anesthesia is required for patient tolerance during the MEG recording (rare).
`76`	Repeat procedure by same physician	When the MEG modality is repeated by the same physician on the same day (if applicable).

Taxonomy Code	Specialty	Notes
207RE0101X	Neurology	Neurologists specializing in clinical neurophysiology frequently interpret MEG studies.
2084P0800X	Neurological Surgery	Neurosurgeons use MEG for pre-surgical functional localization in epilepsy and tumor cases.
207RH0002X	Clinical Neurophysiology	Physicians with specialty in clinical neurophysiology commonly perform and interpret MEG source analyses.

`G40.912`	Localization-related (focal) symptomatic epilepsy and epileptic syndromes with simple partial seizures, intractable, with status epilepticus	Focal epilepsy with intractability is a primary indication for MEG mapping to localize epileptogenic focus and eloquent cortex.
`G40.909`	Epilepsy, unspecified, not intractable, without status epilepticus	MEG may be used in selected epilepsy evaluations when localization is uncertain.
`G44.1`	Vascular headache, not elsewhere classified (migraine)	MEG can be used in research or diagnostic evaluation of cortical excitability in headache disorders (less common).
`C71.9`	Malignant neoplasm of brain, unspecified	Preoperative functional mapping with MEG is used for tumor resections near language or motor cortex.
`R51`	Headache	Symptom that may prompt neurophysiologic evaluation including MEG in select cases.
