Summary & Overview
CPT 95930: Visual Evoked Potential Testing
CPT code 95930 is the Current Procedural Terminology designation for visual evoked potential (VEP) testing, a diagnostic neurophysiology procedure that records the brain’s electrical response to visual stimuli and includes interpretation and report. The code is used nationally to document objective visual pathway assessment for conditions affecting the optic nerve and visual cortex, excluding glaucoma-specific VEP applications. Its inclusion of interpretation and reporting affects billing workflows and bundling rules.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context and typical sites of service, an outline of common modifiers and billing considerations, and an explanation of what is and is not included in the CPT code description. The publication highlights national implications for claims processing and coding compliance, as well as practical points about where the service is typically performed—outpatient hospital clinics, ambulatory neurodiagnostic labs, and neurology specialty settings.
This coverage is intended to orient clinicians, coding staff, and policy stakeholders to the code’s clinical purpose, reporting scope, and payer relevance. Data not available in the input will be noted where applicable.
Billing Code Overview
CPT code 95930 describes a visual evoked potential (VEP) test in which the provider measures the brain's electrical response to a visual stimulus. The procedure includes the interpretation and reporting of results as part of the service and is explicitly not used for VEP testing for glaucoma.
Service type: Diagnostic neurophysiology testing (visual evoked potential)
Typical site of service: Outpatient hospital clinic, ambulatory neurodiagnostic laboratory, or specialty neurology clinic

Clinical & Coding Specifications
Clinical Context
A 38-year-old patient is referred by a neurologist for 95930 visual evoked potential (VEP) testing after new onset blurred vision and an afferent pupillary defect on exam. The patient arrives at an outpatient neurodiagnostic laboratory or hospital outpatient department. A neurodiagnostic technologist prepares the patient: explains the test, confirms informed consent, checks vision correction, places scalp electrodes over the occipital region, and positions the visual stimulus (pattern-reversal or flash) at the appropriate distance. The technologist runs the VEP protocol while monitoring impedances and patient fixation. The provider (neurologist or neuro-ophthalmologist) reviews waveforms, performs the official interpretation and documents findings in a report; interpretation and report are included in 95930 and must not be billed separately. Typical sites of service are outpatient neurodiagnostic laboratories, hospital outpatient departments, and ambulatory surgical centers when diagnostic testing is performed. Common clinical indications include demyelinating disease evaluation (suspected optic neuritis/multiple sclerosis), unexplained vision loss, non-organic visual loss assessment, or neurologic conditions affecting the visual pathway.
