CPT 92541: Electronystagmography / Videonystagmography Eye Movement Recording
CPT code 92541 documents diagnostic recording of rapid eye movements using electronystagmography electrodes or infrared videonystagmography while the head is held static. The procedure provides objective measurement of ocular motor function and is commonly used in the evaluation of dizziness, vertigo, balance disorders, and certain neuro-ophthalmologic conditions. Nationally, this code matters because it captures specialized vestibular/ocular motor testing that can influence diagnostic pathways, referrals, and utilization of downstream services.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical context for CPT code 92541, typical sites of service, and what to expect in coverage and billing discussions. The publication also summarizes national benchmarks where available, common billing modifiers and coding considerations, and how CPT 92541 fits within related vestibular testing codes and clinical workflows.
This overview is intended for clinicians, coding professionals, and policy analysts seeking a clear, national-level summary of the code’s clinical purpose, service setting, and relevance to payer coverage and utilization management. Data not available in the input will be noted where applicable.
